一种新型故障定位方法的研究

RESEARCH ON A NEW FAULT LOCATION METHOD

论述了利用因果网技术进行故障定位的方法。因果网描述了故障元件、继电器、开关之间内在的动作关系，利用了比传统专家系统更深的知识，简单、明确。提出了利用面向对象技术形成因果网的方法，所形成的因果网能适应各种不同的网络，通用性强，且能考虑故障扩大的情形。

Conventional expert systems applied to fault location need to manually build complicated knowledge databases and can not satisfy real-time demand. This paper describes a new method for fault section estimation using cause-effect network technique. Cause-effect network represents causality between the faults and the actions of both relays and circuit breakers. In addition, this paper shows how to use object-oriented technology to automatically form cause-effect networks. The formed networks don't need to consider specific relays and can fit in all kinds of power networks.
