摘要为解决高比例新能源微电网的短时中断问题,提出一种惯性储能永磁发电机组。该文提出的永磁机组由共外转子滚筒的永磁电动机和永磁发电机组成,具有对新能源微电网实时惯性支撑和输出电能质量高的优点。首先,从惯性储能角度出发,结合电网电能质量指标要求对永磁机组进行设计,通过有限元和场路耦合仿真验证了永磁机组设计的合理性;然后,结合永磁机组电磁–机械耦合模型,建立基于PSCAD平台的永磁机组电力系统仿真模型,仿真结果证明了在短时中断故障期间永磁机组可实现对新能源微电网的惯性支撑;最后,研制了一台55kW的缩比样机,通过实验测实验证了设计思想的正确性。

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.

Key words： New energy microgrid inertia motivity permanent magnet machine set inertial support
