摘要
现阶段对分布式电源的研究主要以逆变型分布式电源为主，要实现逆变型分布式电源与负荷形成的孤岛运行或并入电网进行联网运行，逆变型分布式电源的并网控制研究就成为了关键环节。以三相电压型逆变器作为研究对象，首先对并网逆变器的控制系统进行设计，再通过分析介绍不同控制策略下的控制原理及过程，并结合锁相环技术，以实现逆变型分布式电源能够进行孤岛运行或并网运行。
At present, the study of the distributed generation mainly supplys the invertering type power.In order to realize the generation with loads to run on an island, or incorporating into the grid, the research on grid-connection control of the inverter type distributed generation has become a key link.The three-phase voltage type inverter is the research object, first of all the control system of the inverter should be designed, then analysing the control principle and process under the different control strategies, and connecting with the phase-locked loop technology, finaly the inverter type distributed generation is able to run on isolated island operation or parallel operation.
