Description

technical field [0001] The invention relates to a hybrid simulation physical simulation device of a flexible DC converter, which belongs to the technical field of electrical automation equipment. Background technique [0002] At present, the simulation research of flexible DC converter and transmission system control and protection generally adopts theoretical analysis, offline PSCAD simulation / MATLAB simulation and RT-LAB / RTDS real-time simulation platform. Compared with digital simulation, the physical characteristics of the dynamic model physical simulation system are consistent with those of the prototype, and the changes in the relative values ​​of physical quantities such as current, voltage, and power in the model can be compared with those in the simulated prototype system. The process is the same, and the effects such as saturation, hysteresis, and eddy current are often ignored or approximated in theoretical analysis or offline simulation. In dynamic simulation, th...
