基于电压无功象限分布的系统电压控制研究

A Method of Voltage Control Decision for Gird Based on Voltage and Reactive power Distributed on Quadran

系统电压控制涉及发电出力、负荷情况、功率因素、主变档位、无功分布等因素,然而目前并没有适用于系统运行人员对电压控制较为易于理解的决策支持方法。为解决此问题,对影响电压、无功的诸多因素进行统筹分析,依托电压无功象限分布情况,制定了基于电压、无功象限分布的系统电压控制决策方法,并应用于实际运行管控中,取得了一定的效果。

The voltage control of gird always involve crew output, area load, power factor, transformer ratio, reactive power distribution etc. but now haven’t a easy to understand voltage control method for System operator. So we should to analysis factors which inlfuenced voltage and reactive power to solve the problem. Rely on the voltage and reactive power distribution situation, we formulated a method to decision the voltage control of gird, and applied to Operation management, and achieved a certain effect.
