摘要/Abstract

摘要：

目前针对新一代智能变电站二次安措操作的可靠性综合评估仍未有较好的方案，并且缺乏对二次安措操作先后顺序最优执行策略的研究。针对这一问题，从二次安措操作入手，搭建安措链路矩阵，利用模糊综合评价法（fuzzy synthetic evaluation，FSE）量化并综合二次安措执行校核和隔离校核的可靠性数据，将可靠性数据从多维度转化为单一维度。同时量化二次安措操作可靠性和复杂度数据，利用改进贪心算法通过分配两者权重计算各链路安措断开方式的综合评分，按照评分从大到小进行排序，得到各链路最优二次安措执行策略。算例验证，最优二次安措策略较典型的二次安措策略在相同检修次数下各链路未成功断开次数能够降低20%，具有更高的可靠性。

关键词: 二次安措, 可靠性评估, 最优执行策略

Abstract:

Current solutions lack comprehensive reliability assessment for secondary safety measures in next-generation smart substations, particularly regarding operational sequence strategy. This paper addresses this by, first, building an secondary safety measures linkage matrix and using fuzzy synthetic evaluation (FSE) to quantify and integrate multi-dimensional reliability data (execution & isolation verification) into a single metric; second, quantifying secondary safety measures operation reliability and complexity. An improved greedy algorithm, weighting these factors, then calculates a comprehensive score for each linkage's disconnection method. Secondary safety measures execution sequences are prioritized based on these scores. Case verification shows that under identical maintenance conditions, the optimal secondary safety measures strategy can reduce link disconnection failures by 20% compared to typical secondary safety measures strategies, demonstrating higher reliability.

Key words: secondary safety measures, reliability assessment, optimal operational sequence strategy
