摘要: Summary In nonsolidly grounded systems, 3-phase voltage imbalances endanger the system safety. On basis of principle unbalanced control through injecting current, variation along with injected current's amplitude and phase was studied. Three practical closed-loop methods are given, such as 2-point method, tracking synthetic method. The method combines advantages is fast to a high precision. Compared traditional methods, proposed advance in means higher precision, more flexible control, less investments, better adaptation systems dynamic changes. verified designed simulation.
