摘　　要：针对变电站系统后评估过程中的计算效率问题,提出基于邻接矩阵的可靠性评估流程用以分析变电站系统.邻接矩阵所建立的边权模型能够直观地反映系统单元和设备间的逻辑关系,拟Warshall算法通过对邻接矩阵元素的布尔运算高效求解连通性矩阵,从而以Quasi-Monte Carlo模拟方法计算出整个系统的功能状态.基于此评估流程研究了一个典型的6进线10出线220/110/10 kV变电站,计算其抗震可靠性并确定了抗震关键设备.案例分析结果表明,基于邻接矩阵的系统评估思路是可行的,220 kV的电压互感器、断路器、隔离开关及110 kV的隔离开关被评定为变电站系统中最关键的功能设备,提高它们的抗震性能可以显著提高整个变电站系统的抗震可靠性.A reliability evaluation process based on adjacency matrix was proposed to analyze substation system,aiming at the problem of computational efficiency in the post evaluation of substation system.The edge weight model established by the adjacency matrix can intuitively reflect the logical relationship between the system units and the equipment.The quasi-Warshall algorithm efficiently solves the connectivity matrix by Boolean operations on the adjacency matrix elements,thereby calculating the functional status of the entire system by the Quasi-Monte Carlo simulation method.A typical 220/110/10 kV substation with 6 incoming lines and 10 outgoing lines was studied based on this evaluation process.Its seismic reliability was calculated and the key seismic equipment was determined.The case analysis results showed that the system evaluation idea based on adjacency matrix was feasible.220 kV voltage transformers,circuit breakers,isolating switches and 110 kV isolating switches were assessed as the most critical functional equipment in the substation system.Improving their seismic performance can significantly improve the seismic reliability of the entire substation system.
