Analysis and Countermeasures to the Reactive Voltage Operation of Regional Power Grid

This article introduces the operation status of reactive voltage and existed problem of regional power grid,and analyzes in two aspects: the rate of qualified voltage and reactive power.It points out 5 features of reactive operation at present regional power grid such as 500 kV,220 kV and 110~35 kV main transformer′s reactive power,rural power grid's reactive power and partial reactive power,conducts analysis of the reactive power balance and voltage.It finally describes the countermeasures on improving the management of grid reactivity and voltage.
