Application Of Quick Supply Switching For Regional Supply System

As a form of distributed power, backup power plant has become an important part in china's power system, they usually supplies power to regional important customers. The problems about the security and stability of regional systems in larger power networks are urgently needed to resolve. One of the most important problems is the how to ensure the stability of the regional systems when the main grid lost. Combined with the practical project, this paper fully studies the stability of the industrial power network when external faults occur and propose grid measures. Two kind solutions of steady-state grid-connected and transient fast parallel are given. Validity and feasibility of the solutions are illustrated through simulation. Provide a reference for stability control plans of similar grid. At last, an improved integration method for induction motors is proposed. Simulation results show that the calculation accuracy of induction motors in load model can be improved...
