湖南电网短路电流分析计算及抑制措施研究

Short Circuit Current Analysis Calculation and Limiting Measures Research of Hunan Power Grid

随着电网规模持续扩大和特高压输电工程的投产,湖南电网短路电流逐年增长。本文计算2018—2020年短路电流情况,分析短路电流抑制措施效果和可行性,提出了湖南电网短路电流抑制措施。

With the development of network and the commission of UHV transmission project, the short-circuit currents in Hunan power grid increase. This article analyzes short circuit current from 2018 to 2020 in Hunan power grid, and propose the limiting measures are proposed through comparing limiting effect and feasibility.
