有源电力滤波器与高压变频器结合应用研究

Active Power Filter and the High Voltage Inverter Combined Research

根据目前很多大中型企业使用的高压变频器存在的问题,如电网的谐波污染、电网功率因数低,提出了将有源电力滤波应用在高压变频器上。将有源电力滤波器和高压变频器结合起来应用,能很好地实现节能减排,还能减小用电设备对电网的谐波污染和提高自身的功率因数。

At present, according to many large and mediumsized enterprises use high voltage inverter of existing problems, such as the power grid harmonic pollution, power grid power factor low, and puts forward the application of active power filter in the high voltage inverter. The active power filter and the high voltage inverter combined to use, can well realize energy conservation and emission reductions, still can reduce power consumption equipment to power of the harmonic oollution and imnrove their own nower factor
