Abstract：Ultrahigh voltage(UHV) and extra-high voltage (EHV) have been widely used in power system，so the requirement for technology of operation management, as well as the accident analysis and disposal are more pressing. Based on the theory of Newton-Laphson power flow method, this simulation system imitates the primary device and secondary circuit, together with the normal, the abnormal and accidents in operation. Through simulation in various situations, it validates that this design is capable of simulating the complicated faults in UHV and EHV accurately and in real time. In addition, it can analyse and dispose them efficiently.
Key words：ultrahigh voltage (UHV); extra-high voltage (EHV); fault simulation
