Research on high-power pump systems of nongrid connected wind power

Wind energy, because of today´s energy shortages, is coming into alternative energy strategic planning by national governments because it´s clean, as one of the alternative energy sources for fossil fuels. As a new industry, wind power is following the path of sustainable development and circular economy and it has a good future. Now, most of foreign countries connect wind power to the heat power grid and this connection is the only way to use wind power on a large-scale. However, synchronization will lead to the decrease of electricity quality because of the wind power´s intermittency and instability, so wind power is no more than 10% in the proportion of power grid. This reason has limited wind power´s development, which has become a global problem. Non-grid wind power is one of the primary ways to solve this problem. This paper deals with the non-grid wind power that is supplied to a pump using a simulation method. It will select 12Sh-6 type pumps with a full year of meteorological data for the simulation, and finally work out the reservoir capacity to present the feasibility of this program.
