摘　　要：当前越来越多的电源和负荷设备采用电力电子技术并网,降低了电力系统固有的旋转同步和动态电压维持能力,因而需增设一定的同步调相机进行补偿。传统同步调相机的调节能力相对有限,为此,提出了一种新型调相机,增设了一组定子控制绕组,并设计相应的控制器,在多种运行状态下采取不同的控制模式,通过换流器对定子控制绕组的调节,从而灵活控制转子转速与转子旋转储能,扩大了调相机在电力系统动态过程中对有功功率和电网频率的干预能力。最终通过仿真实验验证了该新型调相机的可行性和有效性。At present,more and more power sources and load equipment are connected to power grid by means of the power electronic technology,which reduces the inherent rotational inertia and dynamic voltage stability of power system.As a result,it is necessary to install several synchronous condensers for compensation.Considering that the adjustment capability of the traditional synchronous condenser is relatively limited,a novel synchronous condenser with an extra set of stator windings is presented in this paper,and the corresponding controller is designed.Different control modes are adopted in various running states.By adjusting the regulated stator winding through a converter,the rotor speed and rotational energy storage can be flexibly controlled,thereby extending the condenser’s capability to control the active power and grid frequency in the dynamic procedure of power system.Finally,the feasibility and effectiveness of the novel synchronous condenser are verified by simulation experiments.
