Abstract :
Both the security of the whole network and the operating characteristics of a DC system need to be simulated in detail for a large-scale AC/DC power system. Through transient hybrid simulation, virtues of electromechanical-electromagnetic can be achieved simultaneously. Based on mechanism analysis of electromechanical-electromagnetic transient hybrid simulation, three operation modes of Shandong Power Grid in 2010 are analyzed. Various HVDC faults and the AC faults near the point of fall for HVDC are simulated by the electromechanical transient simulation and the electromechanical-electromagnetic transient hybrid simulation based on ADPSS. Simulation results from two different simulation methods are compared. The superiority of hybrid simulation is demonstrated convincingly through the simulation of commutation failure.
