Problems solved by technology

[0003] Due to the high price and high failure rate of high-power power electronic devices used in rectification and inverter circuits, the cost of wind power generation has always been high, and it is still difficult to compete with traditional power generation methods.
Moreover, after rectification and inversion, there are still certain high-order harmonics in the voltage waveform, which will cause pollution to the power grid.

Embodiment Construction

[0008] A method for combined wind-hydraulic power generation is characterized in that the combination of wind-forced water extraction and hydropower generation comprises the following steps in turn:

[0009] ① Use wind power water lifting equipment to lift water from a low place to a high place;

[0010] ② Make the water flow from the high place to the low place through the hydroelectric power generation device, and push the hydroelectric power generation device to generate electricity;

[0011] ③Repeat the above steps and repeat.

[0012] In the step ①, wind water lifting equipment is used to lift water from a low place to a high place, which can be one level or multiple levels.

[0013] One of the embodiments of the present invention is to use the existing small hydropower station to install one or more wind-powered water lifters near the dam to lift the water from the downstream to the upstream (including multi-stage lifting), and then generate electricity with normal The...

Abstract

The present invention discloses method of combining wind power and hydropower for generating, and features that wind power and hydropower are combined through the following steps: utilizing wind power with water lifting device to lift water to high place; making water flow down to drive hydropower generator to generate electricity; and repeated the foregoing steps. The present invention is superior to available wind power generation, which has high cost, high fault rate and contamination on power network, and may be used alone or as the supplement of hydropower generation.

Description

technical field [0001] The invention belongs to the technical field of power generation, and in particular relates to a power generation method combining wind power water pumping and hydropower generation. Background technique [0002] In traditional wind power generation, the wind turbine directly drives the generator to generate electricity after simple mechanical speed change. Due to the large uncertainty in the size and direction of the wind, the running speed of the fan is unstable, and the electricity generated by it cannot meet the requirements of direct grid connection in terms of voltage, waveform, frequency, etc. Only after the circuit is "reshaped" can it be incorporated into the power grid and realize industrial utilization. [0003] Because the high-power power electronic devices used in rectification and inverter circuits are expensive and have a high failure rate, the cost of wind power generation has always been high, and it is st...
