摘要
Abstract
Based on the mathematical model of 500 kV autotransformer derived in this paper, a simulation model is built up by using power system block set (PSB) in MATLAB software. With the simulation model, anlysis on the 500 kV autotransformer in Qidian substation, as an example, is carried out, and the results show that the no-load closing inrush current may reach upto 1.9 times of the rated current value when transformer is in closing operation. Therefore, the over current protection (such as charging protection) should not be put in during the operation as to avoid possible closing failure.关键词
