In this paper

a kind of reactive power voltage characteristics existed in power grid of a typicalregional is analyzed.For the existed issue of reactive power voltage

the inductive reactive compensationscheme is proposed.On the basis of the evaluation model of reactive power voltage regulation

thecomparison analysis formula for high and low voltage inductive compensation and voltage regulation resultis deduced.The above two kinds of reactive power compensation plan result is analyzed from multipleaspects（voltage regulation efficiency

suitability of development trend of grid in the future

economy andfeasibility on installing compensation device for substation）.It is shown through comprehensive comparisonof above two compensation schemes from above aspects by way of calculation that the voltage regulationestimation formula for high and low inductive compensation which is deduced from this paper has highaccuracy

can be used in the prior estimation of high and low inductive compensation and

at the same time

that in the 220 k V power grid the low inductive reactive power compensation is in general superior to highinductive reactive power compensation.
