摘要：
There is not a photovoltaic array(PV array) electrical model in PSCAD/EMTDC power system electromagnetic transient simulation software standard library,while it is complicated for engineers to write an electrical model in PSCAD/EMTDC. To solve this problem, a user-designed PV array control model is presented using PSCAD/EMDC simulation software based on the mathematical models of PV array, and a constant-current source electrical model can be driven by the current output signal of the PV array control model, by which a real PV array equipment can be simulated. Meanwhile, a MPPT control model is developed and a three-phase grid-connected photovoltaic generation system(GCPS) is simulated in PSCAD/EMTDC. This paper analyzes the effects of sudden changes in solar irradiance on power transmission of the three-phase GCPS, and proves the correctness of the designed control model as well as its availability for engineering simulation analysis.
