Abstract

As for the reactive power compensation control method for the present distribution network which only compensates reactive power but not effectively adjust and compensate three-phase unbalanced load

in this paper

the symmetrical component method is used to transform and analyze the load current and the comprehensive compensation model of reactive power and load unbalance is set up. The capacity of the elements which need compensation is obtained and calculated by way of measuring both active and reactive power of the three-phase load before compensation to control and switch the element group of corresponding externally connected △

Y wiring compensation network and achieve simultaneous compensation of reactive power and three-phase unbalance of the distribution network and

on this basis

the compensation controller is designed to complete comprehensive compensation function of the three-phase unbalance of reactive power and load. It is shown by the simulation analysis and test that the comprehensive compensation method of the reactive power and load unbalance proposed is correct and the designed controller is effective and practical.
