Embodiment
For making the object of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Embodiment one
Please refer to accompanying drawing 1, the wind-powered electricity generation that the figure shows many buildings that the embodiment of the present invention one provides uses the flow process of control method.
Flow process shown in Fig. 1, comprising:
The required power consumption of every building in S101, acquisition unit interval section.
Obtain the required power consumption of every building in unit interval section in step S101, the required power consumption in this step refers to the electricity that can meet all user's actual needs of this building.Obtain process in, a kind of concrete obtain manner is: can check the power consumption in this unit interval section in the past of build, get the maximum of power consumption in the past, and get this maximum as this build needed for power consumption.Unit interval section in this step can be one day, also can be one month, can certainly be several hours, such as 2 hours.
The energy output of the wind power generation system of every building in S102, acquisition unit interval section.
The energy output of the wind power generation system of every building in the unit interval section obtained in step S102, unit interval section is herein identical with the unit interval section in step S101, can be one day, also can be one month, can certainly be several hours, such as 2 hours.
S103, in the unit of account time period, the energy output of wind power generation system of every building deducts the difference of the required power consumption of this building.
In step S103, deduct the difference of required power consumption in this construction unit time period with the energy output in the wind power generation system unit interval section of every building, its main purpose is the electric power thus supplied that the wind power generation system understanding every building is built this.Result of calculation may be zero, if the difference of certain building is zero, then illustrates that this wind power generation system built can be self-sufficient.If the mathematic interpolation result of certain building is just, then represent that the generating of this wind power generation system built has surplus; If the mathematic interpolation result of certain building is negative, then represent that the generating of this wind power generation system built cannot meet needed for the electricity consumption of this building.If the mathematic interpolation result of every building in community is negative or is just, then illustrate that the wind power generation system of every building in community is powered and cannot meet the use of corresponding building, or illustrate that the wind power generation system of every building in community has been powered surplus.If above-mentioned two situations occur, then, in the wind power generation system access mains system every can built, obtain institute's short of electricity energy from mains system or to mains system, supplement the electric energy of surplus.
For in many buildings, mathematic interpolation result just has, and has negative corresponding wind power generation system, is that embodiment of the present invention wind-powered electricity generation uses the object controlled, realizes controlling by step S104.
