摘 要：A power quality analysis method based on electromechanical-electromagnetic hybrid simulation is proposed.The hybrid simulation for power quality analysis can not only enhance the simulation accuracy,and can realize power quality simulation of large scale power system.Then power quality simulation and assessment system is developed based on ADPSS.The system provides plenty of power quality models and achieves power quality simulation based on electromechanical-electromagnetic hybrid simulation.It will provide guidance and reference for power quality study.The hybrid simulation model of an actual large scale power system is built and voltage sag problems caused by short circuit tests are simulated based on the developed system.Simulation result shows the practicality and effectiveness of power quality simulation and assessment system.
