The report of the 17th National Congress of the Communist Party of China puts forward: "We must put a resource-conserving and environment-friendly society in a prominent position in the industrialization and modernization development strategy and implement it in every unit and every family"; "Developing clean energy and renewable energy Protect land and water resources, build a scientific and rational energy resource utilization system, and improve energy resource utilization efficiency." In the days of earnestly studying, propagating, and implementing the spirit of the 17th National Congress of the Communist Party of China, Shanghai Electric Power Company played a combination of energy-saving and emission-reduction punches. The company's energy-saving and emission-reduction work has penetrated into the details of various tasks. Recently, the energy-saving renovation project of the company's office building has been completed. The glass curtain wall energy-saving film, the non-working time of the corridor energy-saving lamp will be reduced by half, the central air-conditioning energy-saving renovation, and the underground garage lighting energy-saving will save about 30%.
Carefully dispatched economic operation
Energy conservation and emission reduction is the systematic engineering of the whole society. In the energy field, it involves all aspects of production capacity, energy transmission and energy use. The dispatching and communication center of Shanghai Electric Power Company is responsible for the safe and reliable operation of Shanghai Power Grid. The center carefully dispatches and services the power plant to ensure the economic operation of the power grid and promote energy conservation and emission reduction.
According to reports, when the Shanghai Power Grid has a small power load, the power company dispatching communication center will transfer the same unit of Waigaoqiao Power Generation Company twice according to the actual situation of the power grid operation. After the unit was shut down, the company issued 800,000 kilowatts of power planned by four units with three units without reducing the total power generation, which improved the monthly power generation utilization rate of the unit. If four units are started at the same time, the coal consumption will increase by 8.46 g/kWh, which will consume more than 3,693 tons of standard coal. This alone will save the power plant 1.6 million yuan. At present, the experts of the power dispatching communication center and the power trading center have completed the project of “replacement of the power generation of the Daidai oblique power generation, and new measures to play an active role in further energy conservation and emission reduction will be introduced soon.
Building a strong grid in Shanghai
In recent years, a large number of major projects such as the “third channel†of the Shanghai power grid, energy conservation and environmental protection – the environmentally friendly 220 kV revitalization station have been completed, making the Shanghai power grid “received, fallen, and steadily deliveredâ€. Out, use," laid a solid foundation for building a strong grid in Shanghai
Shanghai's electricity demand is growing at a rate of about 10% per year. By 2010, the power load will reach 28 million kilowatts. With the current 13 million kilowatts of power generation capacity and 8 million kilowatts of foreign calls, it will still leave about 7 million kilowatts. gap. The Sichuan-Shanghai ±800 kV UHV DC transmission demonstration project with a maximum transmission capacity of 7 million kilowatts has become an important part of Shanghai's best solution for solving energy problems. The Municipal Electric Power Company established the "UHV Office", which is responsible for the preparation of the UHV project. In May of this year, the groundbreaking ceremony for the Sichuan-Shanghai ±800 kV UHV DC transmission demonstration project was held in Shanghai.
Southwestern hydropower green energy is transported to Shanghai, greatly reducing environmental pollution and coal transportation pressure, and promoting the adjustment of China's energy structure. According to estimates, after the project is completed, it can replace more than 6 million kilowatts of coal-fired thermal power units, replacing about 15 million tons of coal, reducing annual sulfur dioxide emissions by 200,000 tons, nitrogen oxides of 40,000 tons, and reducing coal transportation by 15 million tons.
Demand side management and innovation
It is of great significance for energy conservation and emission reduction to use low valley electricity and cut peaks and fill valleys. Since 2000, Shanghai Electric Power Company has actively implemented demand side management and implementation of time-of-use electricity price policy. Promote residents' time-sharing electricity meters. At the same time, Shanghai Southern District Power Saving Technology Development Co., Ltd. was established to try to use technology to implement demand side management, promote scientific electricity use, and guide users to change electricity usage patterns and electricity usage habits. The water-cooled central air-conditioning renovation carried out in 2004 is a typical case of a power-saving company. The so-called water storage air-conditioning system is to store the low-altitude electricity of the power grid at night in the form of cold water, and provide air-conditioning service with cold water during peak hours during the day. The water-storage central air-conditioning retrofit project will transfer nearly 600 kilowatts of peak power during the month of operation, saving nearly 70,000 yuan in electricity costs.
In the past seven years, the power-saving company has transformed air-conditioning equipment for nine users using cold storage technology, and signed energy management contracts with 83 users to transform electrical equipment. Now, in addition to using cold storage and heat storage technology in the end users, the Shanghai Electric Power Company will reduce the daily or seasonal peak load, and also guide enterprises to adopt non-efficient energy-saving equipment, implement energy-saving operation, and adopt energy substitution. Power-saving control technologies and products such as power compensation and high-efficiency transformers, comprehensively implement various measures for energy conservation, loss reduction, emission reduction, and efficiency improvement.
