谐波电流继电器研究

The Research of the Harmonic Current Relay

谐波电流继电器是交流滤波装置的保护电器。有源电感带通滤波器是电子式谐波电流继电器的核心电路。为了满足电子式谐波电流继电器的两项重要技术指标的要求,必须解决有源电感带通滤波器级联时的参数配合问题。本研究解决了这一问题。

The harmonic current relay is the protect relay for the harmonic filtration equipments. The active inductance band pass filter is the key device for the electronic harmonic current relay. In order that the requirements of two important technical targets of the electronic harmonic current relay be met,the Coordination problem of the parameters of the active inductance band pass filter when they are linked each other. The cooraination problem was solved by the research.
