单周控制的四相补偿APF在煤矿电网的仿真研究

Simulation Research of Four-phase Compensation APF Based on One-cycle Control in Coal Mine Power Grid

针对近年来煤矿提升、通风以及运输设备中广泛使用变频器、整流器等电力电子装置所产生的大量谐波问题,提出一种性能优越、实用前景很强且较为先进的单周控制四相补偿APF。把单周控制原理与APF理论相结合,从而推导出该APF控制方程,并设计出相应的单周控制器,最后对此APF在煤矿电网进行了仿真研究。

For a large number of badly harmonic problem produced by widely using power electronic equipments including frequency converter and rectifier in field of hoisting,ventilation and transport system,This article put forward a kind of superior performance,good practical prospect and advanced four-phase compensation active power filter based on One-Cycle Control.Through combination of OCC principle and APF theory,we have deduced the APF control target equation,and according to control target equation,we have designed OCC controller.Finally,we have done research on simulation of four-phase compensation APF based on OCC in coal-mine power grid.
