Embodiment 1

[0036] refer to figure 2 As shown, the coordinated operation system of wind power generation, pumped storage power generation and water power supply includes wind power generation system, pumped storage power generation system, water power supply system and coordination control processor 2;

[0037] The wind power generation system includes an electric energy output terminal for outputting electric energy to the public grid; the pumped storage power generation system includes a pumped storage water pump 7; the water power supply system includes a water tower water tank 16 and a water tank water pump 12 for pumping water to the water tower water tank;

[0038] A power supply circuit is respectively provided between the power output end of the wind power generation system and the power input end of the pumped storage water pump and the water tower water pump;

[0039] The coordination control processor obtains the external wind power demand information and the power generation ...

Embodiment 2

[0048] refer to figure 1 As shown, the coordinated operation method based on the coordinated operation system of wind power generation, pumped storage power generation and water power supply described in Embodiment 1 includes:

[0049] S1, obtaining external wind power demand information;

[0050] S2, obtaining the power generation information of the wind power generation system;

[0051] S3, detecting the water level information in the water tank of the water tower and the water pressure information on the hydraulic supply pipeline;

[0052] S4, calculate the remaining power generation of the wind power generation system, the remaining power generation = power generation - external wind power demand;

[0053] S5, control the power output direction of the wind power generation system according to the remaining power generation:

[0054] If the remaining power generation is less than or equal to 0, then control the power generated by the wind power generation system to only ...

Embodiment 3

[0061] When the system and method of the present invention are applied, when the user’s demand for electricity and water is low at night, the coordinated control processor 2 calculates that there is a surplus in the power generation of the wind power system, and then detects whether the water in the water tower water tank 16 is full. If it is not full, it starts to store water, and the coordination control processor sends water pumping information through the water tank pump control line 9, and the water tank water pump 12 draws water from the water supply pipe 11, and sends it to the water tank 16 at the top of the water tower through the water storage tank 14 and the water tank inlet pipe 15. The controller 10 is used to control the pressure of the water flow, and the water pressure gauge 13 is used to detect the water pressure. The pressure controller 10 and the water pressure gauge 13 can be used together to avoid damage to the water pipes. 17 and water pressure gauge 18 ar...

Abstract

The invention discloses a cooperative operation system for wind power generation, pumped storage power generation and hydraulic supply. The cooperative operation system comprises a wind power generation system, a pumped storage power generation system, a hydraulic supply system and a coordinated control processing device; power supply circuits are arranged between an electric energy output end ofthe wind power generation system and a power source input end of a pumped storage water pump and between the electric energy output end of the wind power generation system and a power source input endof a water tower water pump respectively; the coordinated control processing device is used for calculating the remaining power generation amount of the wind power generation system and controlling the on and off of each power supply circuit according to the remaining power generation amount and running of the pumped storage water pump and a water tank water pump, so that the remaining power generation of the wind power generation system provides a working power source for the water tank water pump or the pumped storage water pump, and the priority of the water tank water pump for utilizing the remaining power generation amount is higher than that of the pumped storage water pump. The cooperative operation system can increase the utilization rate of wind power, reduce wind curtailment andadjust the peak and fill the valley through pumped storage at the same time; the problem of low water pressure of high-rise households in a water use peak period can be solved.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to an integrated system and method for wind power generation, pumped storage power generation and urban water power supply to work together. Background technique [0002] Wind power is one of the renewable energy sources. It is clean in use, low in cost and inexhaustible. Wind power has drawn more and more attention from all over the world. At the same time, wind power also has disadvantages such as a large amount of abandoned wind, instability, and reverse peak-shaving characteristics. Nowadays, with the development of wind power technology, it is imminent to solve the problems of a large number of abandoned wind. [0003] In the existing research, most of the wind curtailment problems are solved by on-site consumption or planning and construction of pumped storage, gas-fired power generation, peak regulation, and frequency modulation power supply. The mode of joint...
