Research On Energy Saving Optimization Of Plant Power System For Double 125MW Units In Jixi Thermal Power Plant

Since the reform and opening to the outside world,China's economy has developed rapidly,and GDP has grown at an annual rate of 8%.But at the same time of economic development,environmental problems are becoming increasingly serious.China is a big country of energy consumption,and energy development and utilization are directly related to the lifeblood of China's economy.Although we are a resource based country with a large variety and huge reserves,our country has a large population,and the per capita resources are quite different compared with those of developed countries.Moreover,many energy resources are seriously wasted due to lack of scientific planning.Therefore,how to use energy efficiently and realize energy conservation and emission reduction is a problem that our country pays more attention to.As a large energy producer and resource,China's thermal power plants are especially waste of resources,and their operation efficiency will directly affect the use of resources in our country.Therefore,the research on reducing the power consumption of power plants is the key to energy conservation and emission reduction in China,and also the key to building a green China and taking the road of sustainable development.In this paper,the present situation of domestic and international thermal power plants is studied,and the gap between the domestic and foreign power plants and the necessity of the study are analyzed.Double 125 MW plant in Jixi thermal power plant unit power system as an example,analysis of the electricity rate at home and abroad to understand the power of the factory,analyzes the reason for the high rate of electricity in Jixi cogeneration power plant,points out that the current Jixi thermal power plant auxiliary power system of the pain problem.Explores the influencing factors of electricity rate of Jixi thermal power plant the.Study the basic measures to reduce the power consumption and reduce the coal consumption of power supply.The energy saving technology of Jixi thermal power plant is studied from the aspects of fan,pump,capacity auxiliary machine and motor frequency conversion speed regulation.And according to the energy-saving technology research,formulate the energy saving technology transformation plan which conforms to the Jixi thermal power plant.Optimize the operation mode of the plant,transform the auxiliary motors of the Jixi cogeneration power plant to achieve the best power matching;select the energy-saving transformer and optimize the lighting system of Jixi thermal power plant to achieve the purpose of reducing the power consumption.The design of the optimization scheme will greatly saving Jixi thermal power plant power,reduce the power consumption rate of Jixi thermal power plant factory of Jixi thermal power plant to create objective economic benefits,is of great significance to optimize the ecological environment.
