Research on Electromechanical Transient-Electromagnetic Transient Hybrid Simulation Algorithm for Power System

With the increasing scale of power grids, traditional electromechanical transient or electromagnetic transient simulation software has begun to reveal its own limitations when analyzing the operating characteristics of the power grid. Realizing the hybrid simulation of electromagnetic transients and electromechanical transients in the power system has expanded the scale of electromagnetic transient simulation. On the other hand, it also provides the necessary system background for the electromagnetic transient network simulation analysis. This paper uses electromagnetic transient-electromechanical transient hybrid simulation technology for engineering analysis and application, which can avoid the system equivalent workload due to the limitation of electromagnetic transient simulation scale, and can greatly improve the accuracy of system analysis and research. For the study of AC and DC systems, DC multi-infeed systems and high-power electronic equipment, the dynamic impact of system operations will effectively play a role, so the electromagnetic transient -electromechanical transient hybrid simulation has become hot spot in the field of power system of simulation.
