中文摘要：

基于SVC和STATCOM的混合无功补偿系统结合了SVC和STATCOM两种技术的优点，可有效消除补偿成本和补偿装置类型之间的壁垒，但在实际应用中，由于补偿容量配置不当，混合补偿系统会出现装机容量过度冗余、补偿装置工作状态混乱、工作效率低下等问题。提出一种基于历史状态的选择性配置策略，通过对历史无功需求量的分析，在既定的分配规则基础上，对补偿额度进行合理分配，有效地提高了补偿装置的工作性能和供电质量。

英文摘要：

Based on SVC and STATCOM and combined the advantages of two kinds of compensation technology, the hybrid reactive power compensation system could effectively eliminate barriers be- tween compensation cost and compensation device types, however, in practical application, because of the improper allocation of compensation capacity, problems such as over redundancy of installed ca- pacity, confused operating state of compensation devices, and low efficiency were caused. A selective allocation strategy was proposed in this paper based on the historical state, and through the analysis of the history of reactive power demand, we allocated rational compensation capacity based on the estab- lished distribution rules and effectively improved the quality of power supply as well as performance of compensation device.
