摘要:
A PI automatic adjustment method based on phase deviation fault residual voltage control is proposed to automatically and stably control the amplitude and phase of controllable voltage sources, achieving fast and effective arc suppression of grounding faults in distribution networks. Abstract Aiming at the problem that the current arc suppression method of coil cannot achieve full compensation. First, the calculation model of the full compensation parameters of the controllable voltage source is established by analyzing the grounding fault arc ...
