评估电气主接线可靠性的专家系统

Expert System for Reliability Evaluation of Power Station and Substation Bus Arrangements

提出了一个考虑元件相关故障和其他多种复杂因素影响的评估电气主接线可靠性的专家系统。该系统以紧凑型数据库为中心，通过一一模拟与辨识电气主接线系统在故障前→故障→故障修复全过程中的各种状态实现可靠性评估。可靠性判据采用“字母－数字码”形式，可输出可靠性及经济损失指标，适用于各种规模和型式的电气主接线形式。大量算例及实际应用的结果令人满意。

: An expert system for evaluating reliability of powerstati on and substation bus scheme arrangements with consideration of relevant failures of elements and various influence is presented in this paper. The core of the expert system is a compact data base. By simulating and identifying the system's state model which consists in operating states, failure states, states between the fault and switching and repair states, we have realized reliability evaluation according to various creteria. Numerical example shows that the expert system gives satisfactory results.
