Aiming at the problem that the transient process cannot be reflected in great detail during the fault by using electromechanical transient simulation and electromagnetic transient simulation cannot describe AC system. Data exchange of the electromagnetic-electromechanical hybrid simulation was analyzed for subnet of electromagnetic transient and electromechanical transient. The ADPSS software,the principle and process of electromagnetic-electromechanical transient hybrid simulation were introduced in detail. Electromagnetic transient simulation,electromechanical transient simulation and electromagnetic-electromechanical transient hybrid simulation are performed respectively based on Debao ± 500 k V HVDC system,the simulation result shows that electromagnetic-electromechanical transient hybrid simulation can effectively analyze local electromagnetic transient process and AC system for large scale power grid. The simulation speed is fast,and the result is accurate and reliable.
