Suppression Metlad of New Magnetic Controlled Reactor to Transient Voltage Rise of DC System
摘要
Abstract
With the rapid development of DC transmission technology in China,a number of DC transmis-sion projects have been put into operation,forming a "strong DC weak AC"grid feature.The bipolar blocking of DC transmission line will cause the bus voltage of converter station in the sending end system to rise,and the magnitude of the voltage rise is related to the DC transmission capacity.Therefore,the transient voltage rise of the sending end system will cause the actual DC transmission capacity to be less than the rated value.The auhtor proposes a method to suppress the transient voltage rise of the sending end system based on a new type of magnetic controlled reactor,and conducts simulation tests with Lugu DC as the test object.The simulation results show that the maximum DC transmission capacity is 7500 MW when the new type of magnetic control reactor is not connected.After the new type of magnetic con-trolled reactor with appropriate capacity is connected,the maximum DC transmission capacity is increased to the rated capacity of 10 000 MW.关键词
