Abstract: In order to weaken the dependence on fossil energy and develop renewable energy sources, the installed capacity of wind power in Xinjiang in China has been increasing year by year. At the same time, the impact of large-scale wind power integration on the traditional distribution network is increasingly significant, especially the short-circuit current when the short-circuit fault occurs,which reduces the reliability of the relay protection and result in instability of the power system. The 110 kV artificial short-circuit test of Xinjiang Power Grid not only carries out the preparation of detailed test plan, but also analyzes the influencing factors of short-circuit current. The analysis of calculated value and test value error based on PSASP power flow mode is implemented. At last, the degree of fit between the different types of wind turbine calculation models of the current power system and the actual situation of the power grid. The error ratio between the calculated current and the measured current with different fault types are obtained, and the influencing factors of the calculated values and the measured values are summarized.
