Technical Field
The utility model relates to an arrangement structure for pumped storage power station belongs to water electrical engineering technical field.
Background
With the large-scale development of new energy such as wind power, photovoltaic and the like, a novel power system taking the new energy as a main body is gradually constructed, and the demand on a flexible power supply is more urgent. The pumped storage power station has the functions of peak regulation, frequency modulation and the like, can ensure the safety of a power system, and promotes the large-scale development and consumption of system energy.
Pumped storage power stations generally include upper and lower reservoirs, water delivery systems, power plants, and the like. The upper reservoir and the lower reservoir generally need the storage capacity of about several million or thousands of cubic meters, the operation of the power station is divided into a water pumping working condition and a power generation working condition, redundant electric power is pumped by a reversible water pumping and power generation dual-purpose unit in the power utilization valley, the water in the lower reservoir is pumped to the upper reservoir, and the water is discharged for power generation in the power utilization peak. When the pumped storage power station is arranged, the pumped storage power station is often influenced by factors such as topographic and geological conditions, environmental protection, immigration and the like. For example, under the condition that the maximum value of the effective storage capacity of the upper reservoir is determined, the upper reservoir and the lower reservoir need to have enough fall to meet the requirement of the installed scale. When an important village is upstream of a planned water retaining dam of a lower reservoir and the water level of the lower reservoir is higher than the important village, a large amount of immigration placement work is often involved, and even proper positions of the upper reservoir and the lower reservoir are reselected.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that: provided is an arrangement structure for a pumped storage power station, which can ensure a sufficient installation scale without flooding important villages.
For solving the technical problem the utility model discloses the technical scheme who adopts is: the utility model provides an arrangement structure for pumped storage power station, including last reservoir and lower reservoir, lower reservoir is formed by the manger plate dam of locating in the river course, be connected through the diversion tunnel between lower reservoir and the last reservoir, the diversion tunnel sets suction pump room and suction pump unit, the water inlet of suction pump unit is located lower reservoir, it is connected with the downstream side river course of manger plate dam through the diversion tunnel to go up the reservoir, the diversion tunnel sets power generation factory building and generating set, the elevation that the position was located in suction pump room is higher than the elevation of power generation factory building position.
Further, the method comprises the following steps: the retaining dam is provided with flood discharge facilities.
Further, the method comprises the following steps: a hydraulic generator is arranged at the position of the water retaining dam.
The utility model has the advantages that: a conventional pumped storage power station is provided with a reversible unit which can pump water and generate electricity, and only one set of water delivery system is provided. The utility model discloses an essence is one set of water delivery system that does not share, divide promptly to set up, one set of suction pump room + water delivery tunnel and one set of power generation factory building + diversion tunnel, the suitable position in upper reaches is removed to lower reservoir, avoid the important village in low reaches, though increased direct investment like this, however, lower reservoir elevation is higher, the lift of drawing water has just become low, corresponding cost of drawing water also can reduce, and the installation scale, the generated energy is unchangeable, and reduced and submerged important village, the settlement investment of moving the people has been reduced. Compared with the scheme that a conventional generator set is directly arranged between the lower reservoir and the power plant, the utility model can increase the installed scale, because the storage capacity of the lower reservoir is fixed, the fall between the lower reservoir and the power plant is much smaller than the fall between the upper reservoir and the power plant, and the installed capacity is naturally small; and the common hydroelectric power station can not utilize the redundant electric quantity of the power grid to be used for the pumping working condition in the load valley so as to achieve the purpose of pumping and storing energy.
