摘要
随着不对称大负荷增加,三相不平衡电流对系统的稳定性影响也日益严重。本文在阐述不对称负载平衡化原理的基础上,分别介绍了基于STATCOM和SVC的三相不平衡负载的平衡化补偿方法,从技术性、经济性和实用性对二者做了对比分析。通过对基于SVC的几种补偿控制算法从原理上进行介绍、分析和比较,使得SVC在应用中可以根据实际情况,考虑各算法优缺点,选择合适的方法。
In order to make solutions for system stable influence of the three phase unbalance current by the increasing of unbalance load, the unbalance load integrated theory is described and the balance compensation algorithm based on STATCOM and SVC has been adopted. Then the technology, economy and utility nature of the two ways are contrasted. Through the introduction, analysis and comparing of the compensation controlling algorithms based on SVC, suitable means could be chosen in application with consideration of actual situation and advantage of different methods.
