寺河矿110KV变电站电能质量研究

摘要

With the coat mine continuous improve the level of automation; power quality becomes more and more important in mine. Any problem caused by power quality will lead to production stopped, even accident. From actual power grid accident of sihe mine, make power quality test and analysis,from the result of test to analysis of three phase unbalance and harmonic.at last to prove the right of analysis through simulation.%随着煤矿自动化水平的不断提高,煤矿用户对电能质量越来越敏感,任何电能质量问题都将导致煤矿生产停顿,甚至发生煤矿安全事故,给用户造成不可估量的损失.文章从寺河矿电网发生的电网事故出发,对其进行电能质量测试,并对测试发现的三相不平衡及谐波超标问题进行分析.通过仿真分析证实了分析结果的正确性.
