Abstract

Distribution network single-phase grounding fault fault point may ignite the grounding arc, the current use of arccanceling coil arc-canceling traditional arc-canceling method of arc-canceling effect is not ideal, and the current active arc-canceling method because of the arc-canceling path of the arc-canceling effect of the theoretical existence of certain differences. In view of the above problems, this topic uses the hybrid arc elimination method combining active inverters and grounding transformers, and according to the different arc elimination ideas to develop two arc elimination schemes, Scheme 1 for the use of active arc elimination devices to force the neutral voltage to change opposite of target phase voltage, Scheme 2 for the measurement of the parameters of the ground, to the neutral point of the injection of the compensation current of the hybrid current calculation Because the control objective of both schemes is that the bus voltage of the faulted phase is zero, they are all active voltage arc extinction in nature. Using Matlab to simulate the difference between the traditional arc elimination method and the hybrid arc elimination method under different fault conditions and compare the arc elimination effect of the two hybrid arc elimination schemes, the simulation results show that the hybrid arc elimination method can eliminate the arc quickly compared with the traditional arc elimination method, and the arc elimination effect of the hybrid voltage arc elimination scheme is better than that of the hybrid current arc elimination scheme under different fault conditions.
