摘要(Abstract)：

针对大量可再生能源并网引起电网惯量支撑不足的问题，构建了一种基于永磁变频调速的飞轮储能调相机模型，并制定了控制方案。在调相机转子配置永磁变频调速的飞轮系统，利用飞轮动能提升调相机的惯量功率响应能力，且可不改变调相机的电网接入方式和快速励磁能力。构建了永磁调速电机及飞轮储能调相机的电磁和机械模型，建立了包含调相机和变频器的双通道耦合功率输出模型，进而提出了基于永磁变频调速的飞轮储能调相机的调频功率控制方案。通过在典型应用场景下的仿真，验证了该方案的可行性与有效性。
To address the issue of insufficient grid inertia support caused by the large-scale integration of renewable energy, a synchronous condenser model of a flywheel energy storage system, along with a control scheme, is developed based on permanent magnet variable frequency speed regulation. This model integrates a flywheel energy storage system with permanent magnet variable frequency speed regulation on the rotor of the synchronous condenser.By utilizing the kinetic energy of the flywheel, the inertia power response capability of the synchronous condenser is enhanced without altering its grid connection method or rapid excitation capability. Both the electromagnetic and mechanical models of the permanent magnet speed-regulated motor and the synchronous condenser of the flywheel energy storage system are constructed. Additionally, a dual-channel coupled power output model that includes the synchronous condenser and the frequency converter is established. Based on this, the paper proposes a power control strategy for synchronous condenser frequency regulation of the flywheel energy storage system using permanent magnet variable frequency speed regulation. Simulations under typical application scenarios have verified the feasibility and effectiveness of this strategy.
