摘要
高压静电除尘器具有数学模型复杂、易闪络等特点,传统的控制器效果不尽如人意。在分析几种常用控制器的基础上,提出了一种不依赖于确切的数学模型而又能随着工况迅速反应的电流滞环控制器。滞环环宽与除尘器电信号是一种映射关系,理论表明,所提出的控制器可以更好地满足除尘器在闪络和反电晕工况下的快速响应需求。PSIM仿真和工程试验证明,采用该控制器的除尘电源充分增强了粉尘粒子的荷电能力,明显提升了平均电晕功率和除尘效率。
High voltage electrostatic precipitator has the characteristics of complex mathematical model,easy flashover. The traditional control strategy is unsatisfactory in control effect. Established on the basis of the analysis of several common control strategies,a current hysteresis controller which did not depend on accurate mathematical model was proposed in complicated operating conditions. There was a relationship of mathematical model between hysteresis-band and electrical signals of electrostatic precipitator,hysteresis-band could be adaptively changed according to different conditions instead of the traditional fixed band,theoretical analysis results showed that this controller can be better to meet the demands in flashover and anti corona conditions with the adaptive control method. PSIM simulation and engineering test results show that electrostatic precipitator using this controller can enhance the charging capacity of dust particles fully,and enhance the average corona power and efficiency markedly.
