Development And Intelligent Optimization Of Control System For Electrostatic Dust Removal High Frequency High Voltage Power Supply

In recent years,the rapid development of industrial level led to more and more serious environmental pollution problems,especially air pollutant emissions have seriously affected people's health.In order to control air pollution and improve air quality,a variety of dust removal technology applicate to industrial production more and more,electrostatic dust removal technology has significant advantages,but now widely used traditional power frequency electrostatic precipitator on the market due to its limitations is difficult to meet the requirements of the relevant indicators.In this case,with the output voltage ripple small,adaptable,small volume easy to install and transport characteristics of high-frequency electrostatic dust power came into being,has been widely used.This paper do the following aspects about high frequency and high voltage electrostatic dust power supply system development and optimization:Firstly,the circuit topology and working principle of LCC resonant converter of high frequency electrostatic precipitator are expounded.The mathematical model and loss equation of LCC resonant converter are established.The LCC resonance based on genetic particle swarm algorithm in continuous and discontinuous mode is studied emphatically The optimal design method of the converter parameters is compared with the genetic algorithm results,and the results of the genetic particle swarm optimization algorithm are better.Then,the rationality of the design is verified according to the field experiment results.Secondly,the mathematical model of electrostatic precipitator with high power and high frequency and high voltage transformer is analyzed.The optimization design method of high frequency transformer based on genetic particle swarm optimization is studied emphatically,and the concrete design process and optimization result are given.Finally,the field experiment shows that the algorithm has certain guiding significance.Then,carried out the control system hardware,software design.Hardware circuit includes DSP board,analog board,power board,digital board,driver board and ARM as the master chip communication hardware design.The software design mainly includes system initialization,self-test program,fault judgment and spark detection.The realization of the power supply system with Modbus / TCP protocol as communication method is described.In addition,the design of supervisory software based on MCGS is designed.Finally,the field simulated load test of high frequency and high voltage electrostatic precipitator is carried out in the field.The experimental waveform is given and analyzed.The results show that the system design has reached the expected requirement.
