Abstract

This paper presents an implementation of a Virtual Synchronous Machine (VSM) based on a Modular Multilevel Converter (MMC). The control system relies on the internal simulation of an electromechanical swing equation, which emulates the inertia and damping effect of a synchronous machine and provides the frequency and phase angle needed for controlling the MMC to operate as a VSM. The ac-side control is based on cascaded voltage and current controllers in a synchronous reference frame defined by the virtual swing equation. The reference signals for the ac-side voltage control are generated from a reactive power control loop and a quasi-stationary virtual impedance which emulates the equivalent voltage drop over the stator windings of a synchronous machine. The control system also includes internal control loops for regulating the double frequency circulating currents of the MMC. The presented VSM implementation is tested in a laboratory environment using an MMC with 18 half-bridge sub-modules per arm. Experimental results demonstrate the operation of the VSM-controlled MMC when connected to an external ac grid and in islanded mode feeding a resistive load.

作为虚拟同步机控制的模块化多电平变换器的运行
提出了一种基于模块化多电平转换器的虚拟同步机的实现方法。控制系统依赖于机电摆动方程的内部仿真,该方程模拟了同步电机的惯性和阻尼效应,并提供了控制MMC作为VSM运行所需的频率和相位角。交流侧控制是基于由虚拟摆幅方程定义的同步参考系中的级联电压和电流控制器。交流侧电压控制的参考信号由无功功率控制回路和模拟同步电机定子绕组上等效电压降的准平稳虚拟阻抗产生。控制系统还包括用于调节MMC的双频循环电流的内部控制回路。所提出的VSM实现在实验室环境中使用每个臂有18个半桥子模块的MMC进行了测试。实验结果表明,vsm控制的MMC在与外部交流电网连接并以孤岛模式馈送电阻性负载时运行良好。
