Abstract-Skill training of UHVDC Operators is becoming increasingly important with the rapid construction of UHVDC projects. It is necessary to build a simulation system to meet the training needs. This paper presents a fully digital software simulation program. The entire system can run on a computer, which includes the Operators Work Station system, the primary equipment and the second equipment scene simulation, while in the background of AC/DC hybrid power grid and control & protection system simulation. This simulation system provides training for the operation of the UHVDC converter station with the simulation of the whole scenes of Jinping -Suzhou UHVDC transmission project as the prototype of the training system.
Abstract. The protection system simulation is an important part of the simulation training system for the UHVDC converter station. It is an important indicator of the fidelity of the training system to accurately simulate the protection action after the fault. In this paper, a simulation method for protection based on logic judgment method is proposed. According to the fault information, the protection strategy is searched and implemented from the protection strategy library, which avoids the complicated fault power flow calculation and the protection start judgment calculation. In this way, the simulation system of Jinping -Suzhou UHVDC transmission is developed. The actual effect shows that the protection simulation method based on logic judgment method can meet the needs of the operator training.
