本文分析了风电的三种利用模式，详细阐述了非并网风电理论，探讨了风电等可再生能源通过多能源协同供电应用于高耗能产业，即非并网风电的内涵。研究分布式发电和非并网风电理论的关系，分布式发电作为非并网风电的一种表现形式，将非并网风电与现存电力系统构建为一个完善的电力系统框架。

This paper analyses the three modes of?use of wind power，and detailedly elaborates the non-grid-connected wind power theory，discusses the?wind power and other renewable energy through the multi energy cooperative power supply applied to high energy consuming industries，namely the connotation of non-grid-connected wind power.And it discusses the relationship between distributed generation and non-grid-connected wind power theory. As distributed generations is a form of non-grid-connected wind power，the non-grid-connected wind power and the existing?power system will build a perfect framework of power system.
