摘要
采用新的有源无功补偿与滤波器原理方案,通过信号采集电路采集电网信息,然后通过高性能的TMS320F2812智能控制系统对电力系统信号进行检测、数据处理及计算,得到有关高次谐波的信息,产生控制信号到IPM驱动电路中,控制有源滤波器组对电网中的无功电力与谐波进行补偿,达到预定的效果。并对电网的实时监测、对滤波器监控与电网动态信息实时在LCD上显示出来。此系统在理论仿真与实际电网电力系统无功电力与谐波补偿中取得了良好实验的效果。
A new approach of reactive power compensation and filter principle is provided, which is used to compensate reactive power and different harmonic. This model mainly includes signal-collected circuit, TMS320F2812, intelligent power module（ IPM）, LC filter and LCD. F2812 is regarded as the CPU of this system, which detects signals, carries out calculation, data analysis and gains necessary information. Through IPM drive circuit and LC filter, the control signals compensate the electric net. Meanwhile, the rela- tive information can be displayed on LCD. This system shows good performance not only in the theory simulation, but also in the real harmonic compensation of the electric power system.
