摘要

考虑到插头设置（PS）、时间乘数设置（TMS）和继电器特性系数（λ和γ），定向过电流继电器（DOCR）的操作时间可以通过用户定义的继电器特性来缩短。本研究对继电器协调与标准和用户定义的继电器特性进行了比较分析。所提出的继电器协调方案被公式化为一个非线性约束优化问题。灰狼优化（GWO）算法用于确定DOCR的最佳继电器设置和总操作时间。在标准的8总线、9总线和15总线系统上测试了所提出方案的性能。结果表明，具有自定义继电器特性的DOCR的总工作时间优于具有标准继电器特性的DOC。将GWO算法的结果与文献中用于解决继电器协调问题的优化技术的性能进行了比较。

Optimal Relay Coordination for DG-Based Power System Using Standard and User-Defined Relay Characteristics

The operating time of directional overcurrent relays (DOCRs) can be reduced with user-defined relay characteristics considering plug setting (PS), time multiplier setting (TMS), and relay characteristic coefficients (λ and γ). This study presents a comparative analysis of relay coordination with standard and user-defined relay characteristics. The proposed relay coordination scheme is formulated as a non-linear constraint optimization problem. The grey wolf optimization (GWO) algorithm is used to determine the optimal relay settings and total operating time of DOCRs. The performance of the proposed scheme is tested on the standard 8-bus, 9-bus, and 15-bus systems. The results show that the total operating time of DOCRs with user-defined relay characteristics is better than that with standard relay characteristics. The results of the GWO algorithm are compared with the performance of optimization techniques used in literature to solve the relay coordination problem.
