Optimization Design of Power System Access for Typical Dispersed Wind Power Engineering

针对分散式风电离负荷中心近、自发自用、就地消纳、多点接入的特点,结合工程设计实际,归纳了接入系统的方法.按不同电压等级、不同容量给出相应的接入系统方案以及一二次设备的配置原则,具体包括接入原则、接入系统要求、接入点电压选择、接入典型方案设计、方案优化等内容,为并网工作的顺利开展提供一定的技术支撑.

Considering the characteristics of dispersed wind power,such as its nearness to load centers,self-generation and self-use,local consumption and multi-point access,combined with the engineering design practice,the methods of acessing the system are summarized in this paper.According to difterent voltage levels and capacities,corresponding access system schemes and configuration principles of primary and secondary equipment are given,including access principles,access system requirements,access point voltage selection,access typical scheme design and scheme optimization,which provide certain lechnical support for the smooth development of the grid-connected work.
