The motor direct-drive operating mechanism directly drives the high-voltage circuit breaker to realize the opening and closing actions by controlling the motor to run according to the travel curve.Ai-ming at the lack of a systematic planning method for the travel curve of the direct-drive operating mecha-nism,which cannot match the operating characteristics of the mechanism,has a long planning,validation and optimization period,and has poor portability,a travel curve planning method for the direct-drive op-erating mechanism was proposed by combining the polynomial model and the load characteristic model.Based on the kinematics and dynamics analysis,a mathematical model of the load characteristics of the direct-drive operating mechanism was established.The polynomial model was used to generate travel curve clusters,and a multi-objective optimization algorithm was established by combining the characteris-tics of the motor direct-drive operating mechanism and the high-voltage circuit breaker to screen out the optimal travel curves.Simulation and experimental results show that the proposed scheme can achieve stable and reliable operation of the motor direct-drive operating mechanism and high-voltage circuit break-er,and compared with the traditional travel curve planning method,it can optimize the energy consump-tion by 10.3%,which can further improve the overall power density of the control system.
