Field Debugging of UHV AC Extension Project in China

摘要

To make sure that the UHV AC extension project can be carried out successfully, a software for power system simulation is used to analyze system commissioning tests, including the switching test of the low-voltage reactive-load compensation equipment, the switching test of 1000kV no-load line with series capacitors, the switching test of series compensator, the artificial earth short circuit test etc. The simulation results are compared with the measured data in tests. Research results show that the simulation results are basically consistent with the field measured data. Moreover, the simulation calculation model, the calculation parameters, and the calculation tool can meet the demand of the engineering research. It provides the reliable technical basis for future analysis and control of the interconnected network operation.
