Research Of Control Method In High Voltage Electrostatic Precipitation Power Supply With High Performance

With the implementation of the national energy conservation and emission reduction policy,the emission of waste gas from thermal power plants is more stringent,and the existing dust removal equipment is difficult to meet the emission requirements of thermal power plants.When the ESP power supply works,it needs to generate enough charged particles to realize the charged dust.At the same time,in order to avoid flashover,arc and anti-corona phenomena of ESP power supply,it is necessary to optimize the structure of ESP power supply and improve the control mode of ESP power supply.Based on this,the system structure and control mode of high voltage electrostatic dust removal power supply are studied in this paper.Through theoretical analysis and operation of equipment,the control method of high voltage electrostatic dust removal equipment is studied.In this paper,the existing electrostatic precipitation equipment and control technology are studied,the current structure of electrostatic precipitation power supply is analyzed,and the control mode of common electrostatic precipitation power supply is studied.The overall structure of high voltage electrostatic precipitation system is introduced,and the working principle of high voltage power supply is analyzed.The overall structure of the high voltage electrostatic precipitator power supply is introduced in detail.The functions of each part of the power supply system are described in detail in combination with the schematic diagram of the power supply structure.The PWM control mode of power converter is introduced,and the PWM control mode of high voltage electrostatic precipitation power supply is selected and...
