基于二十一区图的农网变电站无功优化控制策略研究

Research on Reactive Power Optimization Control Strategy of Substation in Rural Power Network based on Twenty-one District Circuit Diagram

阐述农村配电网变电站中无功优化的重要性,同时指出农村配电网变电站无功控制策略缺乏全局性观念,在此基础上利用二十一区图控制策略,并制定二十一区图参数整定方法。该控制策略加强了在极端运行的方式下变压器两侧配电网之间的协调控制,可作为常规运行方式下的有益补充。

The article expounds the importance of reactive power optimization of substations in rural power distribution network.Meanwhile,it points out that the reactive power control strategy of substations in rural power distribution network is lacking of overall concept,and base on this,it makes the method of parameter tuning of twenty-one district circuit diagram.The control strategy strengthens the coordination control between power distribution network of transformers＇ sides under extreme running,it can be used as useful complement to the normal operation mode.
