【Abstract】 The optimal design of HVDC control and protection parameters in the case of large-scale AC and DC power system network is a valid measure to ensure achieving good transient and stable performance.Real-time simulation is unsuitable for this case due to its limited network node and high cost.According to the hardware configuration used for HVDC control and protection system and operation mechanism of modular advanced control for HVDC and SVC(MACH2)from ABB company,the realization principle and method for non-real time simulation to obtain the same effect compared with the real time operation is presented.The validity is demonstrated by comparing the non-real time simulation results with actual ones.The method proposed is also used to realize the current control function of HVDC in practice.The results show that the simulation results can agree well with real time simulation ones and the optimal design of HVDC with high efficiency can be realized by using the method in commercial common software environment.更多还原
