Abstract:

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.

Key words: Quasi-Monte Carlo simulation    substation system    basic network model    seismic reliability    key equipment identification
