摘要
随着我国新颁布的火电厂大气污染物排放标准(GB13223-2003)的实施,对电除尘器高压电源在节能与优化控制方面提出了更高的要求。根据电除尘器典型运行工况要求,建立了电除尘器高压供电优化控制数学模型。以这些数学模型为基础,采用遗传算法进行了电除尘器高压供电优化控制的仿真研究,最终开发出能指导电除尘高压电源的设计与运行的优化控制仿真软件。分析和数值仿真结果表明,通过实施从后级电场向前级电场逐级调节供电参数的方法,可使电除尘器高压电源的节能与优化控制性能达到最佳状态。
Since the emission standard of air pollutants for thermal power plants （GB13223 - 2003） was put into effect in China Jan. 1st , 2004, strict voltage optimization control demands have been put forward for ESP. Based on the discussion of the voltage control demands, a mathematical model of voltage optimization control for ESP is proposed. The simulation of the voltage optimization control for ESP is completed with genetic algorithm. The optimization simulation software is developed, which can offer references for power supply of electrostatic precipitator. Theoretical analysis and simulation results show that there is an optimum point between high overall efficiency and low power consumption, and the optimum voltage control for ESP can be achieved by auto regulating the running parameters of the electric fields from rear to front.
