Abstract：In order to solve the short-term interruption problem of high-proportion new energy microgrids, an inertia motivity permanent magnet machine set (IMPMMS) was proposed. The IMPMMS proposed in this paper is composed of a permanent magnet motor and a permanent magnet generator with a common outer rotor roller, which has the advantages of real-time inertial support for new energy microgrids and high output power quality. From the perspective of inertial energy storage, the IMPMMS was designed according to the power quality index requirements of the power grid, and the rationality of the IMPMMS design is verified by finite element method and field-circuit coupling simulation. Combined with the electromagnetic-mechanical coupling model of IMPMMS, a simulation model of IMPMMS power system based on PSCAD platform was established. The simulation results prove that IMPMMS can realize inertial support for new energy microgrids during short-term interruptions. Finally, a 55kW scaled prototype is developed, and the correctness of the design idea is verified through test.
