The conclusion has directively meaning to APF exploitation and application.
上述结论对有源电力滤波器的开发与应用有指导性意义。

The control strategy of active power filter APF has low accuracy and bad robustness.
有源电力滤波器已成为解决这一问题得关键性技术。

But the cost of APF is expensive, so this disadvantage restricts the practical application.
但有源滤波器的成本太高, 这缺点又限制了其实际应用。

One key problem with APF application is how to accurately calculate harmonic currents for compensation.
有源滤波器得应用中要求补偿电流得指令值计算要准确。
