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.
