Wind-driven water pumping electric generating system

Abstract

A wind water-pumping generating system includes a reservoir, a water turbine, a generator connected with the water turbine and a transmission system. A lower reservoir is built below the height of outlet end of the water turbine. The lower reservoir forms a water delivery passage with the upper reservoir via the water pump set. Each water pump of the water pump set is connected in the wind generating system, which comprises a stabilized DC generating set consists of a fan, a pressure-regulating device and a rectifier and a power-splitting controller. When there is wind, the wind generating system starts to work, and the water pump can delivery the water in the lower reservoir back to the upper reservoir, so that the water can be used circularly.

Description

technical field

[0001] The invention relates to power generation technology, which is a power generation system combining wind power generation and hydropower generation. Background technique

[0002] Due to its rich resources, environmental protection and other advantages, wind power is gradually being paid attention to. However, due to the instability of wind power distribution in time and the instability of wind power, the continuity of power generation is poor. Sometimes when the grid load is heavy, it cannot generate power due to no wind, and sometimes when the grid load is excessive, it can only be used for power generation. A supplement to the power grid cannot be used as the main energy source. In addition, because the wind turbine involves grid connection, the control device is complicated, and the unit cost is high, which increases the cost of power generation and is not conducive to popularization.

[0003] On the other hand, the hydropower system can generate e...
