摘　　要：新能源电站在无功补偿装置配置设计上普遍执行冗余配置原则,如控制策略不当,运行中易出现无功功率过剩的问题。研究了一类风光互补新能源发电系统内联络线无功传输问题,通过无功功率传输本质原理分析、光伏电站系统无功配置冗余度校核及基于BPA的新能源系统建模仿真分析,明确了此类系统内联络线无功功率过剩的主要原因,并提出了系统策略及装置性能等方面的改进建议。In the configuration design of reactive power compensation devices of new energy power stations,the principle of redundant configuration is generally implemented. If the control strategy is not appropriate, the problem of excessive reactive power is easy to occur during operation. This paper studies a class of reactive power transmission of tie-line in a wind-solar hybrid new energy power generation system. Through the analysis of the essential principle of reactive power transmission,the redundancy check of reactive power allocation in photovoltaic power station system and the modeling and simulation analysis of new energy system based on BPA,the main reasons for excessive reactive power of tie-line in the system are clarified. Some suggestions for improving the system strategy and device performance are put forward.
