三相不平衡的危害及解决方法

Harm and Solution of Three Phase Unbalance

分析电网三相不平衡运行愈发严重问题产生的原因,并总结归纳其在发电、输电、配电以及用电环节造成的危害。通过探讨无功补偿、拓扑重构以及换相调节等解决措施得知,换相调节是未来解决三相不平衡问题的重要研究方向。

This paper analyzes the causes of the increasingly serious problem of three-phase unbalanced operation of power grid,and summarizes the harm caused by it in power generation,transmission,distribution and power consumption.Through the discussion of reactive power compensation,topology reconstruction and commutation regulation,we know that commutation regulation is an important research direction to solve the three-phase imbalance problem in the future.
