the business opportunities brought by the Beijing Olympic Games to the emergency power industry

At present, the Beijing Olympic Games has entered a real countdown stage, a lot of related preparatory work are highly carried out and improved, and every link about the Olympic Games is taken seriously by people. The recent power outage in Jinmao Tower in Shanghai has raised people's view of emergency power to a higher level and paid special attention to the emergency power system for the Beijing Olympic Games.

There may be many people who are a little unfamiliar with the concept of emergency power, but EPS emergency power is an emergency power device (EPS:EmergencyPowerSupply) that allows short-term power outages. As a fire emergency power supply system, when a fire breaks out in a building, it provides centralized power supply as evacuation lighting and other important primary power supply loads. when the AC municipal power supply is normal, the AC municipal power supply is supplied to the important load through the mutual switching device. when the AC municipal power is cut off, the mutual switching device will immediately switch to the inverter for power supply, and the power supply time is determined by the capacity of the battery. The emergency power supply will be restored to municipal power supply.

The EPS emergency power supply mainly adopts SPWM (AC Pulse Band Modulation) technology, which mainly consists of rectifier charger, battery pack, inverter, mutual switching device and so on, in which the inverter is the core, and the function of the rectifier is to turn AC into DC, to supply power to the battery and to the inverter module. The function of the inverter is to convert the direct current into alternating current to supply the stable and continuous power of the load equipment, and the mutual switching device ensures the smooth switching of the load between the city power and the output of the inverter; the system controller monitors the whole system in real time and can send out alarm signals. at the same time, it can be connected with the computer or Modem through the serial port to realize the microcomputer monitoring and remote monitoring of the power supply system.

At present, the EPS fire emergency power supply specially designed and developed by some enterprises for fire emergency measures has a certain advance and practicability. It can completely realize microcomputer monitoring and processing, all of which are automatic and modular, and can realize automatic control of fire emergency lighting, rolling shutter doors, fire elevators, water pumps, smoke exhaust fans and other fire fighting facilities. At present, the product is mostly used in some large high-rise buildings, airports, telecom office buildings, important venues and other projects. It has the following characteristics: 

When there is electricity in the ● power grid, it is static, noise-free, less than 60db, does not need smoke exhaust and shockproof treatment, and has the characteristics of no pollution and no fire hazard.

● automatic switching, can achieve unattended, energy saving, the switching time between power grid power supply and EPS power supply is 0.1mur0.25s.

● has strong load capacity, EPS is suitable for inductive, capacitive and comprehensive load equipment, such as fire elevator, water pump, fan, emergency lighting, etc., especially in the case of accident or fire, the power supply can work at 120% overload until the battery is completely exhausted. 

● can be used reliably and can be used in important occasions to ensure reliable power supply in case of accident and fire. at the same time, the life of the main engine can be more than 20 years, and the battery can last more than 10 years.

● adapts to the harsh environment and can be placed in the basement or power distribution room, or even in the building shaft. It can be set up on the spot close to the emergency load and reduce the power supply line. Can be controlled on the spot, can also be controlled by the fire linkage.

● for some high-power electrical facilities, such as fire pumps, fans, EPS can also be directly connected to the motor after frequency conversion start, and then enter the normal operation state, can save the motor soft start and control box and other settings.

● emergency standby time: the standard type is 60 minutes (with delay interface), which can be long or short.

● when talking about fire emergency power supply, many people will think of UPS power supply, yes, UPS has many advantages, but also used in a lot of fire work, but compared with EPS, it is not the best. The use of uninterruptible power supply (UPS) power supply mode can make the load "foolproof", but UPS is expensive, especially in winding UPS, its conversion efficiency is low, long-term continuous operation, will inevitably lead to a waste of electric energy, in fact, UPS is widely used in information loads, in emergency, accident lighting occasions to use UPS is undoubtedly "overqualified".

The arrival of ● Beijing Olympic Games will bring many business opportunities to emergency power manufacturers and enterprises, and will also lead the emergency power industry to a healthy development. Next, let's take a look at the business opportunities behind this industry from the relevant situation in Beijing.

First, Beijing Olympic fire emergency will promote the development of emergency power supply.

Security is the fundamental guarantee and main symbol of the success of the Beijing Olympic Games, and it is also a priority for the preparation, organization and implementation of various actions for the Beijing Olympic Games. Fire safety is a very important aspect of Olympic safety goals and tasks. There have been many fire tragedies in sports venues in the world, which can be taken as a warning. We should also attach great importance to the terrorist attacks of the 1972 Munich Olympic Games and the bombing of the 1996 Atlanta Olympic Games. After the 9 / 11 incident in the United States, high-tech vicious terrorist crimes have become more important. In addition, during the Olympic Games, people gather in various places such as hotels, big business markets, transportation hubs, entertainment places, and so on, and fires will cause panic and confusion, and even casualties; lifeline facilities such as urban gas, electricity, communications, and so on, its fire safety needs to be absolutely sure.

In order to further improve the quality and level of fire protection and security preparations for the Olympic Games, effectively ensure fire safety during the 2008 Olympic Games, and create a good fire safety environment for successfully hosting a "distinctive and high-level" Olympic Games, to lay a good fire safety foundation for the realization of the strategic concept of "New Beijing New Olympic Games" In accordance with the working thinking of the Beijing Municipal Public Security Bureau's "overall prevention and control, accurate guidance" and the Beijing Fire Corps's "long-term plan and short-term arrangement, while grasping the root cause and treating the symptoms at the same time," the policy of early intervention, high starting point, high quality, orderly progress, and gradual implementation ", the Beijing Fire Corps is actively conducting a survey on the basic situation of fire safety in the places involved in the Olympic Games, and has achieved phased results.

The Beijing Fire Corps placed the fire and security preparations for the Olympic Games in the overall work of building a harmonious and safe society in the capital, considered and planned the work before 2008 as a whole, and established that the preparatory work for the Olympic Games should be taken as the leader to drive and promote the daily work. The daily work should take the Olympic requirements as the standard, realize the quantitative change to the qualitative change, and achieve the "three combinations". That is, to combine the preparation for the Olympic Games with the improvement of working ability. Combine the preparation for the Olympic Games with the improvement of the overall quality of the troops, and the preparation for the Olympic Games with the improvement of work quality and work efficiency. To do a good job in daily work as the basis for solving the fire safety environment of the Olympic Games.

According to the overall plan of the security preparations for the Olympic Games, up to now, the Olympic Games Office of the Fire Protection Department of the Beijing Fire Corps and the relevant fire prevention departments, departments and brigades have successively completed 6 Olympic Games reconstruction and expansion competition venues, 41 Olympic Games independent training venues, 88 contracted hotels and 20 designated hospitals. Investigation on the basic situation of fire safety Completed a total of 77 Olympic Games competitions, training venues and related facilities and venues within 200 meters around the three categories of fire safety investigation, including Fengtai, Xuanwu, Shijingshan Fire Protection Department research content is rich and accurate, high quality Finally, the Olympic Games Office of the Ministry of Fire Protection will comprehensively study and analyze the current situation of public fire-fighting facilities, key fire safety units and whether there are dangerous sources of flammable and explosive dangerous goods within 200 meters around all kinds of places. to form a "fire safety risk assessment report". The research results and research reports have laid a foundation for a more scientific and reasonable formulation of fire safety and security plans, fire-fighting plans and fire supervision, inspection and management of places involved in the Olympic Games. In addition, the relevant research reports were also promptly provided to the Beijing Olympic Organizing Committee, the Beijing Municipal Government's "2008" Project Construction headquarters, the Olympic Security Coordination Group, and other relevant units, playing an important role in the preparations for the Olympic Games.

Olympic power supply has become the top priority of Beijing's Eleventh five-year Plan.

According to forecasts, Beijing's electricity consumption in 2010 is between 75 billion kWh and 82 billion kWh. It is estimated that the power load in Beijing will reach about 15000 megawatts in 2008 and 16700 megawatts in 2010.

The new plan proposes that during the Eleventh five-year Plan period, Beijing will strengthen power construction and improve supply capacity; formulate safeguard measures to ensure the safety of power supply for the Olympic Games; eliminate hidden dangers in power grid security and ensure the safe operation of power grid; establish and improve emergency management system; improve emergency response mechanism and other nine key development tasks.

Among the nine tasks, "formulating safeguard measures to ensure the safety of power supply for the Olympic Games" has become a crucial one. Beijing Electric Power Company has launched the "Beijing Electric Power Grid '0811' Project" on September 28, 2006. With reference to the international advanced power grid structure, the "0811" project of the power grid will implement four major projects: "Olympic supporting Project", "Power Grid Security Project", "Power Grid Emergency Project" and "Power Grid blanking Project".

1. Characteristics of Power supply and demand and load status in Beijing during the Tenth five-year Plan period

Due to regional resource constraints and environmental protection requirements, it is not suitable to build a large number of power plants within Beijing. 2/3 of the power of Beijing power grid is supplied from outside the region, and the proportion of external power transmission is relatively high, which is a typical receiving end power grid. The construction of outgoing telecommunication channels and contact lines plays an important role in Beijing's power supply.

With Beijing's economic and social development and the improvement of people's living standards, Beijing's electricity demand has maintained a high growth rate during the 10th five-year Plan period. From 2001 to 2005, the electricity consumption of the whole society in Beijing increased from 39.994 billion kilowatt hours to 57.054 billion kilowatt hours, with an average annual growth rate of 9.3 percent. The maximum load on the hour increased from 6994 megawatts to 10538 megawatts, with an average annual growth rate of 10.7 percent.

As the proportion of air conditioning load has increased year after year (it has accounted for more than 40% of the peak load), the peak load in this city has increased significantly, the peak-valley difference rate of the power grid has been close to 50%, and the pressure of power supply during peak hours is relatively high. It can be predicted that if effective DSM measures are not taken, with the continuous increase of power demand, the peak-valley difference of power grid will continue to expand, and the difficulty of power balance will increase year by year.

With?? Some changes have taken place: the proportion of electricity consumption in the primary industry has continued to decline slowly, from 3.3% in 2001 to 2% in 2005; the proportion of electricity consumption in the secondary industry has decreased slightly, from 51.65% in 2001 to 49% in 2005; the growth momentum of electricity consumption in the tertiary industry is good, with the proportion of electricity consumption rising from 28.26% in 2001 to 33.41% in 2005 The domestic electricity consumption of urban and rural residents has increased rapidly, with the proportion of electricity consumption rising from 5.90% in 2001 to 15.59% in 2005.

During the 10th five-year Plan period, while carrying out the construction and transformation of the power grid and strengthening the management of production and operation, Beijing comprehensively investigated the hidden dangers existing in the Beijing power grid, and carried out the rectification of the hidden dangers offline and "three lines". The external environment of power grid operation is improved. At the same time, the research and formulation of electric power emergency disposal plan and the organization of emergency exercises have further enhanced the ability of Beijing power grid to deal with emergencies.

two。 Development Environment and demand Forecast of Beijing Electric Power during the Eleventh five-year Plan

Beijing is the national political and cultural center and the center of international communication. The positioning of Beijing's national capital, world city, cultural city and livable city has special requirements for the safety and reliability of power supply.

During the Eleventh five-year Plan period, on the basis of optimizing the structure, improving efficiency and reducing resource consumption, Beijing will achieve the goal of an average annual GDP growth of 9 per cent and a doubling of per capita GDP by 2010 compared with 2000. The rapid economic growth will lead to a sustained increase in power demand and create good conditions for the development of Beijing's power industry.

According to the analysis of load characteristics and growth trend in Beijing area, it is estimated that the maximum load in Beijing area in 2008, 2010 and 2020 will reach 13556 MW, 15833 MW 16700 MW and 26870 MW 29130 MW respectively. Taking into account the moderately advanced development of electric power and the requirements of the high security margin of the capital power grid, in 2010, according to the 16700 megawatt plan, the load grew at an average annual rate of 9.6% during the Eleventh five-year Plan period. In 2020, the load is planned according to the load demand of 29000 megawatts, with an average annual growth rate of 5.6%.

According to the load forecast and the analysis of electricity demand growth, it is estimated that the electricity consumption of the whole society in Beijing will reach 695-74.5 billion kWh, 750-82 billion kWh and 1327-148.5 billion kWh in 2008, 2010 and 2020, respectively. In 2010, according to the plan of 75 billion kilowatt hours, electricity consumption grew at an average annual rate of 5.6% during the Eleventh five-year Plan period.

3. Formulate safeguard measures to ensure the safety of power supply for the Olympic Games

After such a great effort in electricity, there should be very little shortage of power supply during the Olympic Games, but some unexpected events make it impossible for anyone to guarantee the sudden power outage. "Don't be afraid of 10,000, just in case." No one dares to make such a big bet. Therefore, the preparation of emergency power supply is very important. The electric power emergency mechanism needs to be further improved, the social electric power emergency mechanism is not perfect, and the emergency power supply for important users is insufficient. It is necessary to conscientiously study and establish an effective emergency mechanism of the capital electric power, so that in the event of serious and serious power security accidents, we can efficiently organize and coordinate central and local resources, unified command and joint action, and jointly carry out emergency rescue work.

Here, we can boldly predict that the preparation and holding of the Beijing Olympic Games will bring unexpected harvest to the manufacturers and enterprises of emergency power supply.
