基于九区图的变电站电压无功控制策略研究

Strategy Research of Substation Voltage Reactive Control Basing on the Ninth Region Plot

电压和无功调节是各级变电所要承担的重要任务,为保证电压质量、无功平衡和电网安全可靠经济运行,对变电站实行电压无功自动控制已成为一项重要的控制措施。文章对基于九区图的各种变电站电压无功控制原理和策略进行了综述,介绍了其演变过程,详细分析了其存在的主要缺陷及在使用中可能会出现的问题,并对VQC的发展方向做一概述。

Every substation should undertake the Voltage and re active regulation a s an important task, in order to ensure the voltage quality, reactive balance, a nd the safe and reliable operation of power grid, it becomes an crucial control measure for the substation adopts the voltage reactive automation control. The p aper introduces the evolvement process of the substation reactive control princi ple and strategy basing on the ninth region plot, and analyses its existing bug and th e problem which may be occurred in the application course, as well as makes a br ief introduction about the VQC development direction.
