Description
Technical field
The utility model generally relates to energy field, and relates more specifically to a kind of solar-thermal generating system.
Background technology
The characteristics of wind power generation is that generating capacity is stronger when load valley, but user had no in load valley it is prosperous
The demand of Sheng, and the energy storage system without Large Copacity at this stage, therefore wind is abandoned in generation.
Cause the reason for wind power generation " abandoning wind " reason mainly there are four aspects：
First, the planning of wind power plant and the planning of power network occur in that uncoordinated, the construction speed of wind power plant to a certain extent
There is asynchronous problem with the particularly transmission project construction of whole power network, have impact on the normal operation of wind power plant.
2nd, due to local economic development, the industrial structure, wind-powered electricity generation can not be in local consumption completely, so there is one
Electricity is divided to send out.So among the process sent out, the deficiency for sending out transmission line of electricity ability also have impact on submitting.
3rd, wind-powered electricity generation has uncertainty in itself, also has intermittence, its operation needs power network to carry out cooperation, that is, needs to carry out
Peak regulation.There are some local, peak load regulation network scarce capacity, particularly three northern areas of China, the ground such as North China, northeast, northwest is in the winter time
Heated, this needs first has to ensure the operation of heating unit, and this causes peak regulation to go wrong, and does not permit in the method for operation
Perhaps in the case of, also cause to abandon wind.
4th, also needed in the mechanism policy of whole wind power plant operation further perfect.
According to statistics, China drug in some provinces wind-powered electricity generation abandons wind up to 20% or so, " three Norths " (northeast, North China and northwest) some wind money
The abundant area in source or more than 30%, direct economic loss reaches nearly 10,000,000,000 yuan.
And photo-thermal power generation load is concentrated mainly on daytime, by regenerative apparatus, night Turbo-generator Set can underload fortune
OK, if wanting night also to generate electricity at full capacity, it is necessary to increase the investment of Jing Chang and regenerative apparatus or by increasing fuels such as coal, day
The nonrenewable resourceses such as right gas increase the running rate and full capacity of steam turbine.
Prior art is solved wind-powered electricity generation by the way of wind-light-electricity complementary and fluctuates the impact caused to power network, and its technical scheme is
Dc power is directly fed battery charging by wind-power electricity generation and photovoltaic generation by corresponding controllers respectively, then by inverse
Power network is delivered to after change device is grid-connected.The deficiency of Independent Power Generation can be so compensate for, is transmitted electricity when being effectively reduced respective independent operating
The fluctuation of power, reduces part and abandons wind or abandon light.
But, although existing wind-light complementary system can solve part and abandon wind, also can power network to produce some bad
Influence, such as island effect, harmonic pollution, can not also solve in addition three northern areas of China heat in the winter time peak load regulation network when wind of abandoning ask
Topic.
