The Synchronverter technique is an example of a virtual synchronous machine‐based control method for PWM controlled power electronic converters that enable converters to mimic the behavior of a synchronous generator (SG). It is based on the well‐established mathematical model of an SG and should equip converter connected generation with the capabilities of providing the grid with ancillary services such as frequency/voltage support due to the inherent capabilities of the SG. In this paper, the Synchronverter control method is applied to a wind energy conversion system (WECS) connected to the grid using back‐to‐back converters. The mathematical models of the control system for both the rectifier side and the inverter side are elaborated and used to derive the required transfer functions. A tuning procedure is proposed, using the transfer functions of the system, to enable a fast and easy adaption of the control method to power systems with different parameters. Simulations have been performed to validate both the functioning of the proposed tuning procedure and the ability of the WECS to provide the grid with ancillary services. The results are promising, showing the controllers yielding fast and accurate responses to contingencies and changes in power set‐points without steady‐state deviations.

Synchronverter技术是用于PWM控制的功率电子转换器的基于虚拟同步机的虚拟控制方法的示例，该方法使转换器能够模仿同步发电机（SG）的行为。它基于SG完善的数学模型，并且由于SG的固有功能，因此应使与转换器相连的发电设备具有为电网提供辅助服务（如频率/电压支持）的功能。本文将同步变频器控制方法应用于使用背靠背转换器连接到电网的风能转换系统（WECS）。阐述了用于整流器侧和逆变器侧的控制系统的数学模型，并将其用于导出所需的传递函数。提出了调整程序，使用系统的传递函数，可以使控制方法快速轻松地适应具有不同参数的电力系统。已经进行了仿真，以验证提议的调整程序的功能以及WECS为网格提供辅助服务的能力。结果令人鼓舞，表明控制器可对突发事件和功率设定值的变化做出快速而准确的响应，而不会出现稳态偏差。
