Abstract

The invention relates to an evaporative cooling wind power water-pumping energy storage co-generation system which is characterized in that the output end of a wind power generation equipment (1) is connected with the input end of a water pump (2) through a connecting mechanism (10), the water pumping port of the water pump (2) is communicated with a lower reservoir (3) through a water pumping pipe (11), the water outlet of the water pump (2) is communicated with an upper reservoir (4) through a water outlet pipe (12), the water inlet of a water pumping energy storage machine unit (5) is communicated with the upper reservoir (4) through a power generation water conduit (14). The water outlet of the water pumping energy storage machine unit (5) is communicated with the lower reservoir (3) through a draft pipe (13). The wind power generation equipment (1) and the water pumping energy storage machine unit (5) all adopt a stator evaporative cooling method.

Description

technical field [0001] The invention relates to a pumped storage combined power generation device using wind energy. Background technique [0002] With the increasing shortage of world energy and the increasing trend of global warming, as one of the important means of energy conservation and emission reduction, the world's wind power generation has developed rapidly and its technology has continued to improve. In the past five years, the world's wind power market has grown at a rate of (40%) every year , my country's wind power market is also showing a good development trend in recent years. However, wind power generation is greatly affected by the regional environment. It is unstable power, and the reliability of power generation is poor. Only when the power grid (at least ten times the capacity of the wind farm) is connected to the grid can the effectiveness of wind power be brought into play. This is limited in many occasions, such as some areas with abundant wind energy...
