Research on Electromagnetic Electromechanical Hybrid Simulation of Multi Fed DC Power Grid with CLCC Converter Station

The structure and working principle of CLCC are analyzed, the simulation software E-Tran Plus is used as the interface, combined with the mature software PSCAD and PSSE to form an electromechanical-electromagnetic hybrid simulation platform, the functions and principles of the simulation software are introduced in detail, and a simple electromechanical-electromagnetic hybrid simulation is carried out through a small system to compare with the pure electromagnetic simulation study. The theoretical and simulation results show that the electromechanical-electromagnetic hybrid simulation model using E-Tran Plus interface software is characterized by high accuracy and fast speed, which can better reflect the dynamic characteristics of the AC system and is closer to the actual engineering, and it provides an important reference value for the future large-scale electromechanical-electromagnetic hybrid simulation study of AC and DC power grids.
