Research Of Voltage And Reactive Power Auto Control In Substations Based On The Factor Of Harmonic

Along with the widely use of power electronic equipments,the damage causedby harmonic becomes worse to power system.The harmonic likely results in parallelvibration or series vibration in partial power syetem,the harmonic is magnified.Theexcess current caused by harmonics possibly brings damage to capacitors and electricequipments.This paper will restrain the harmonic and optimize the control strategy ofVQC through taking full advantage of capacitors and inductors.With the simulationanalysis of MATLAB, based on hormonic,the function of VQC will be improved and theequipments will be effectively protected,ajusting the voltage and reactive at the sametime.
