基于ADPSS的直驱风机半实物仿真研究OA

A high proportion of new energy equipment brings problems such as increased power supply uncertainty and weakened rotational inertia to the power grid.By simulating a large-scale power grid with refined models of new energy equipment,the operational control characteristics of the equipment can be fitted,control strategies can be verified,potential risks of the power grid can be prevented in advance,and the safety of the power grid can be effectively improved.In order to solve the accuracy problem of the new energy equipment model,a semi-physical simulation platform close to the actual equipment was used to carry out high and low voltage ride through and other working condition simulations.By using ADPSS technology,a DC unloading circuit was established using relevant basic components.Combined with the relevant two-level converter control strategy,a detailed semi-physical simulation electromagnetic model of a single-motor dual-power unit two-level direct-drive fan was built.And by optimizing the model through direct frequency control method,the stability of semi-physical simulation was enhanced.The comparison of results shows that the direct frequency control method optimizing the model reduces the volatility of the simulation and greatly improves the accuracy of the simulation.
