Study on electromagnetic transient simulation model of Shandong power grid with HVDC

摘要

Based on the parameters of the Shandong power grid and the Ningdong-Shandong HVDC system, an electromagnetic transient model of the Shandong power grid, which includes generators, transformers, transmission lines, reactive power compensation devices etc., is constructed in the PSCAD/EMTDC environment. The electromagnetic transient model of the HVDC system includes the converter stations and the control systems. By adjusting the power flow distribution of the grid and three-phase short-circuit currents of the buses in main substations, the dynamic characteristics of grid are proved to be nearly equal under the program of PSCAD and PSASP.
