摘要
本文提出了一种新的电网实时结线分析方法，这种方法借助人工智能的知识表示及推理技术，对电网结构进行符号化表示，避免了传统方法对设备端点进行手工编号的工序，并省去了许多关联表。这种方法具有编程简单、易于调试等优点，已被成功地应用于我们所开发的电网事故处理专家系统，以借助传统计算程序解决棘手的环网过负荷问题。本文还提出了紧急状态下过负荷校正的简易算法，此算法将有功分量校正同无功分量校正分解进行，提高了求解效率，并减小了求解空间。
This paper proposes a new method for the realtime topology analysis on power systems,which is based on the representation and inference techniques of artificial intelligence. The representation of electric network configuration is symbolized,so the conventional manual procedure to number equipent terminals is eliminated,and many tables related to the power system connectivity are not necessary. Thus this method is simple and efficient in writing and debugging the programme to determine the network topology.It has been successfully applied to our expert system for power systems restoration.Furthermore,a simplified algorithm for overloads relief is presented,which is basedon the decoupling of active and reactive optimal power flow corrections. It can solve the overload problem in loop power systems efficiently with less computer memory.
