摘要
Abstract
In the neutral ungrounded power distribution system, ferroresonance is easy to occur in certain conditions due to the nonlinear characteristic of excitation inductance of three-phase potential transformer (PT), and this phenomenon may decrease the security of power system. In this paper, simulation analysis and comparison are performed via ATP-EMTP software for the ferroresonance and various ferroresonance elimination methods. Combining the simulation analysis and practical application, it is concluded that of many ferroresonance elimination methods, connection of ferroresonance eliminator to the neutral point of PT's primary side and 4PT connection are the best ones.关键词
