Holographic multi-scenario UHVDC converter station anti-accident deduction platform can analyze the cause of fault quickly and it is an indispensable means of fault analysis. But for the converter station, because of its model is not suitable to be built, the logic of the protection program is complex, and the simulation workload is large, so far there is no converter station anti accident deduction system. A holographic multi scene UHVDC converter station anti accident platform is developed, including PSCAD model calculation engine, simulation control system, converter station operator workstation and 3D virtual reality server. For the first time, the automatic conversion technology of converter station control and protection program is used to reduce the modeling workload while ensuring the accuracy of simulation; through the automatic test technology, various operation modes and fault types of model simulation are carried out in batches to improve the efficiency of simulation test; at the same time, the platform display system adopts the holographic three-dimensional technology to realize the visual display of the primary and secondary equipment of the whole converter station operation. In the process of anti accident simulation and verification, the earth fault of pole bus is simulated and inverted, the result is consistent with the action result of field protection device, and the accuracy is high. The platform can provide effective technical support for operators and maintenance personnel to carry out anti accident deduction, fault simulation preview and control and protection strategy analysis.
