Research on Neutral Grounding Reactance Allocation with MCR

Abstract:

For the arc current generated during the reclosing of the high-voltage transmission system, small reactance configuration compensation and control strategy. By the magnetically controlled reactor is researched. First analyzing the principle that high-pressure single-circuit and double-circuit on the same pole line suppresses arc current, then establishing the magnetron controlled reactor equivalent model in PSCAD, on this basis, establishing simulation using magnetron reactors to suppress secondary arc current circuit under the conditions of high voltage transmission lines , designing and implementing of a magnetic valve controllable reactor inhibition of arc current physics experiments under of a low-voltage experimental conditions analoging high-voltage actual line condition. At last, the comparison of PSCAD simulation waveform and physics experiments of Power Quality the analyzer topas2000 and oscilloscope output verify the magnetic valve controllable reactor to suppress the arc current theory feasibility and effectiveness.
