Description
Technical field
The utility model relates to a kind of wind-powered electricity generation and accumulation of energy association system, especially relates to the complementary system of a kind of wind-powered electricity generation and pumped storage associating.
Background technique
In recent years, along with the continuous exhaustion of conventional fossil energy and becoming increasingly conspicuous of environmental problem, a large amount of development and use in green, renewable energy seedbed become the trend of various countries' energy development.Power industry is energy consumption and greenhouse gas emission rich and influential family, and green, renewable energy power generation progressively substitutes the direction that traditional thermal power generation is the power industry development, to alleviating energy crisis, to reduce greenhouse gas emission significant.Wind-power electricity generation becomes the selection that various countries at first develop with its technology advantage ripe relatively, that cost is lower, the amount of accumulateing is huge, renewable and free from environmental pollution in numerous new energy industries such as solar electrical energy generation, tidal power generation.
Wind-powered electricity generation is different with conventional power supply, and wind-powered electricity generation has very strong randomness, is the energy at a kind of intermittence, and the reliability availability of generate output is difficult to guarantee.The motive force of wind-power electricity generation is uncontrollable, and whether it is in generating state and the size of exerting oneself all is decided by wind speed, the unstability of wind speed and intermittently cause exerting oneself of wind-powered electricity generation unit also to have wave properties and intermittent characteristics.Under existing technical merit, wind-power electricity generation also can't accurately forecast, so wind-powered electricity generation is non-scheduling basically.From the angle of electrical network, the wind energy turbine set that is incorporated into the power networks is equivalent to a disturbing source with randomness, and the stable operation of electrical network is affected.
Consider from the angle of environmental protection and renewable energy utilization, wish to enlarge the scale of wind-power electricity generation as far as possible, and the characteristics of wind-powered electricity generation itself make it be incorporated into the power networks to the quality of power supply and the certain threat of safety and stability formation of electrical network.The motive force of wind-power electricity generation is natural wind, therefore the restriction of the main wind-engaging resource distribution of addressing of wind energy turbine set, when the planning construction wind energy turbine set, at first to consider wind energy content and geographical conditions, yet wind resource area preferably is often sparsely populated, the electric load amount is little, and a little less than the electric network composition relative thin, the trend that the injection of wind power has changed partial electric grid distributes, grid voltage quality and stability there are relatively large influence, may limit mode and the scale of wind energy turbine set connecting system.
Wind-powered electricity generation is because its randomness not only can't provide effective adjustable generate output, and its variation that provides spare capacity to exert oneself with the balance wind-powered electricity generation at any time is provided in the anti-system that needs.Therefore, according to the difference of power supply architecture, regulating power, power network topology and part throttle characteristics, the wind-powered electricity generation capacity that set electric power system can be born in different developing stage is limited.The maximum injecting power of wind energy turbine set not only depends on the regulating power of other power generating equipment in the roadability of wind energy turbine set and the system, and also the network structure of the system that inserts with wind-powered electricity generation etc. is all multifactor closely related.Mainly comprise: the power of wind energy turbine set access point load capacity; The connecting mode of wind energy turbine set and electrical network; The size of the regulating power of conventional unit in the system; The type of wind-powered electricity generation unit and reactive-load compensation situation and regional load characteristic etc.Considering that wind-powered electricity generation is exerted oneself changes fast, intermittent factor such as big, uncertain strong, for reliability of system operation after not limiting Power Output for Wind Power Field and keeping wind-electricity integration, need be on the basis of the original method of operation, the extra spinning reserve of a constant volume of arranging is kept the power-balance of electric power system with stable with the random fluctuation of response wind energy turbine set generated output.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of wind-powered electricity generation and accumulation of energy association system for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions: a kind of wind-powered electricity generation and accumulation of energy association system, it is characterized in that, comprise blower fan generator set, hydroelectric power system, pump group and main control computer, described blower fan generator set, hydroelectric power system connect main control computer respectively, the using electricity system of described pump group connects blower fan generator set and hydroelectric power system, and the intake pipe of pump group is connected hydroelectric power system respectively with outlet pipe.
Described hydroelectric power system comprises upper pond, lower reservoir and generator, and the power output end of generator connects main control computer.
Described pump group is provided with at least one suction pump, and the intake pipe of described suction pump connects lower reservoir, and outlet pipe connects upper pond.
Described blower fan generator set, hydroelectric power system are by the gate-controlled switch pump group that is connected in parallel.
