摘要
无功测量在电力系统中有着重要的地位和作用。本文分正弦和非正弦两种情况,论述了包括移相法,积分法,Hilbert法等在内的几种主流各种无功测量方法,对现有方法的精度和误差进行了分析,探讨了各种方法下的误差应对策略。并简要介绍了各种方法的软硬件实现的可行性。
The reactive energy measurement plays an important role in power system. Several prevalent methods such as digital phase shift method, integration method and Hilbert transform method for reactive power measurement are introduced in this paper. The measuring error and the methods of correcting the error are also analyzed. The feasibilities of the hardware and software based on these methods are discussed simply.
