在本文中，对逆变器进行操作以模拟同步发电机（SG）的想法被提出并加以发展。我们将以这种方式运行的逆变器称为同步逆变器。使用同步逆变器，用于控制同步发电机的成熟理论/算法仍然可用于发电容量中很大一部分基于逆变器的电力系统。我们描述了同步逆变器的动态特性、实现方式和运行情况。并联连接且作为发电机运行的同步逆变器所输送的有功功率和无功功率可使用众所周知的频率和电压下垂机制自动分配。同步逆变器也可轻松在孤岛模式下运行，因此，它们为微电网或智能电网提供了理想的解决方案。文中给出了仿真和实验结果以验证这一想法。
In this paper, the idea of operating an inverter to mimic a synchronous generator (SG) is motivated and developed. We call the inverters that are operated in this way synchronverters. Using synchronverters, the well-established theory/algorithms used to control SGs can still be used in power systems where a significant proportion of the generating capacity is inverter-based. We describe the dynamics, implementation, and operation of synchronverters. The real and reactive power delivered by synchronverters connected in parallel and operated as generators can be automatically shared using the well-known frequency- and voltage-drooping mechanisms. Synchronverters can be easily operated also in island mode, and hence, they provide an ideal solution for microgrids or smart grids. Both simulation and experimental results are given to verify the idea.
