分布式发电并网系统综述

随着分布式发电(Distributed Generation)应用的增加,越来越多的分布式发电正在接入电网,由此带来的并网问题日益重要:并网系统(包括硬件和软件)主要用来连接分布式发电和电网(通常是本地电网),本文主要讨论了分布式发电与电网之间的并网类型,并网系统的分类、功能、主要结构及采取的控制方法,并简要介绍了现有的分布式发电并网导则。

Interconnection System to Connect Distributed Generation to Grid

With the development of Distributed generation(DG) in the power system,DG is expected to become more important in the future generation system.And more and more DG are interconnected to the grid.The increasing connection of DG to the grid has driven a lot of issues.The interconnection system is the equipment(both hardware and software) that makes up the physical link between DG and the grid(usually the local electric grid). This paper discusses the interconnect relationship about the DG and grid,In addition,the terms about the types,function,main scheme and control method for DG interconnection system are discussed,the guidelines for interconnecting DG with Electric Power Systems are presented,too.
