Abstract:In order to solve the problem of reactive power regulation, transient overvoltage, light load loss and other issues of the EHV long distance grid, the dynamic characteristics of one product level 800kV EHV magnetically saturation controlled reactor using self-power supply control system are analyzed, and the harmonic suppression method by adding 5th and 7th filters between the control system and the energy supply coil is proposed. Firstly, the mechanical structure and operating principle of the MSCR are analyzed in detail. Then, the body characteristics, control characteristics and step properties of the MSCR are expounded. Finally, the harmonic suppression is analyzed by experimental method. The dynamic characteristics are studied by experimental method, and the correctness of the proposed harmonic suppression method is verified. The theoretical basis for the analysis of dynamic characteristics and harmonics suppression of the EHV MSCR are provided by the study results.
