The use of electricity information acquisition system can obtain the electricity consumption information of the users in real time and provide data source for the related work of the power system.In view of lack of effective index for quantitative comparison of different types of reactive power compensation schemes

in this paper

a kind of evaluation system of reactive power compensation in low pressure area considering comprehensively voltage quality and economic efficiency on the basis of such related data as real time voltage and power factor which is obtained by the electricity information acquisition system.The evaluation system can be used for a low pressure platform area in a certain region and its rationality is verified.It is proved that this method can evaluate the comprehensive benefits of different reactive power compensations schemes.
