摘要
论述了 WFH- 3B/ 2型微机式发电机匝间保护装置在原理方面的设计思想 ,主要讨论了负序功率方向元件的实现过程及差分算法在本装置中所起的作用 ,并且简单介绍装置的动作判据和功能。
The paper states the principle that generator main protection-micro-processor is based on type WFH-3B/2 inter-turn protective device. The implementation of negative-sequence power direction component is mainly discussed, the mathematic algorithm applied is simply explained and the protecting functions of the device are introduced as well..
