配电网中三相不平衡动态功率调节装置的应用研究

Study of the Dynamic Power Regulator for Three-phase Voltage Unbalance in Distribution Network

配电网中三相负荷不平衡给设备及用户造成了很大的影响与危害,本文结合配电网系统结构,分析了三相不平衡问题产生的原因及传统的抑制方法,在此基础上研制出了三相不平衡动态功率调节装置,提出了一种特有的智能半自冷的散热方式,同时介绍了该动态功率调节装置的工作原理和全封闭的整体设计方案,并进行了相关的性能测试实验,实验结果验证了该装置应用的可行性和有效性。

By analyzing the influence and harms, caused by unbalance of three-phase load in distribution network, structure of the distribution network, based on the causes and solutions of this unbalance problems, the thesis proposed the Dynamic Power Regulator（DPR） for threephase voltage unbalance and one intelligent thermal mode which is semi self-cooling. At the same time, the working principle and the overall plans of the DPR is introduced. The related performance test is carried out. The experimental results verify the feasibility of the scheme.
