摘要
本专家系统采用了以开关跳闸信号为主进行故障判断的新方法,并通过了以东北辽西电网为对象的离线测试。同国外用保护动作信号进行故障判断的专家系统相比,本专家系统的应用范围更广,既适用于保护信号和跳闸信号都具备的电网调度中心,也可用于只具备跳闸信号的调度中心;它的知识库具有更深层的知识,电网保护的配置原则被隐含在故障模型之中,从而取消了庞大的电网保护数据库,为本专家系统移植到其它高压输电网带来了方便。另外,本专家系统对各种保护动作的可靠性按照运行经验进行了区分,增强了故障判断的准确性。
It is a new way applied in this expert system that breaker tripping signal is used to diagnose the failures. The system has passed the off-line test taking Liao Xi network of northeast of China as the object. Compared with the overseas expert system diagnosing failures by the signal of protecting operation; the system can be used more widely, it can be used in the net dispatching centers providing both protecting' signal and tripping signal or the only tripping signal. In order to disannul the enormous net protecting data base, the rule of net protecting configuration is laid in the failure model. This makes it convenient for the system to be used in other high voltage power transmission network.
