Electrical Design Of Flue Gas Desulfurization Unit For 2*300MW Supercritical Unit In A Power Plant

In today's society,environmental protection has been deeply rooted in the country,while China is a big country of coal,the use of limited water resources,resource structure to determine the energy structure.Therefore,the power supply of our country is still mainly based on thermal power,but the thermal power will bring serious pollution of the flue gas,the flue gas desulfurization equipment is very important at this time.Thermal power generation is an important way to obtain electrical energy in China.Under the background of the national haze burst table,the Electric power tech should be improved.For a long time,China's power progress lags behind the economy.And the control of air pollution lags behind the industrial development.In order to have more places with the "APEC blue",the construction process of electric power is being accelerated while the power plant emissions requirements are also more and more strict.This design briefly introduced the process and characteristics of the limestone-gypsum wet flue gas desulfurization(WFGD)and the electrical design of the flue gas desulfurization device of 2 * 300 MW supercritical unit.By selecting the electric connection mode,load calculation and calculation of the short-circuit current,the design of the desulfurization device of low-voltage distribution system,DC system,UPS system,lightning protection system and emergency security system have been compeleted,and the electrical equipment were layout.Finally related drawings were drawn by using CAD software.
