摘要
有源电力滤波器是一种对有害电流进行动态补偿的装置,其有害电流检测电路是决定补偿性能好坏的关键环节。只有迅速准确地检测出有害电流才能产生补偿电流。谐波电流的检测方法有许多种,所以有必要对各种检测方法做一比较以便充分利用每一检测法的特点。
Active power filter is a kind of device used for dynamic compensation of harmful current. Harmful currents detecting circuits are essential and indispensable parts of active power filters that determine their compensating characters. There are so many harmonic current detecting methods that it is necessary, to compare various methods in order to take full advantage of the characteristics of each method.
