摘要:With the development of power system, the safe and reliable operation of power grid is the most important. It is impossible for the actual system to conduct experiments on every operation condition of the power grid, simulation software is used to simulate possible faults in the system and to build components or control systems to avoid serious faults. Compared with electromechanical transient, electromagnetic transi-ent simulation software can simulate the actual working conditions more accurately. Based on the electro-mechanical transient PSASP simulation model and component parameters of an actual UHVDC transmissi-on system, the electrical parameters are converted to RTDS, and the electromagnetic transient simulation model is built in this article. In order to keep the steady state of the two stable operating conditions, the p-ower flow of each branch is calculated through the PSASP power flow calculation function module, and the output of the generator in RTDS is adjusted, so that the power flow on the line is basically the same as that of the generator. The short-circuit current of the outlet bus of the equivalent machine is calculated by the PSASP transient calculation, and the reactance of the generator in the RTDS is adjusted to allow the short-circuit current to be within the allowable range of the engineering error.
