Technical field
The utility model relates to a kind of wind-light-diesel and holds micro-grid power generation system, belongs to renewable energy utilization technical field.
Background technology
Along with the increase of International Petroleum Price continuous rise and domestic coal price rise pressure, China's energy supply is being faced with unprecedented severe situation.And the new regenerative resource of R and D becomes one of necessary effective way of China's sustainable economic development.In west area, although the range of application of solar energy and wind energy is more and more wider, apply more isolated.Simultaneously solar energy and wind energy be subject to season and climatic influences larger, the stability of wind-force and solar power generation is difficult to guarantee, for load with electrical stability and the higher region of continuation, generation of electricity by new energy is difficult to meet user's normal life and need of production.
Utility model content
Utility model object: the utility model is unstable in order to solve the supply of electric power that the grid-connected power generation system such as existing solar energy and wind energy cause by the effect of natural conditions such as season and weather, continuation is poor, in some periods, there is again the problems such as the wasting of resources of generation of electricity by new energy simultaneously, the utility model provides a kind of wind-light-diesel to hold micro-grid power generation system, can produce for user, household electricity, also can working shop of enterprise, public buildings etc. are subject of implementation, pass through wind generating technology, photovoltaic effect generation technology, be aided with diesel generating set and batteries simultaneously, can meet user produces, the stable need for electricity of living.
Technical scheme: a kind of wind-light-diesel holds micro-grid power generation system, comprises wind turbine generator, solar battery, diesel generating set, batteries, integrated manipulator and inverter; Described solar battery is for solar power generation; Described diesel generating set is for supplementing supply of electric power; Described batteries is used for storing and discharging electric energy more than needed; Described integrated manipulator is for the switching of voltage monitoring and control switch; Described inverter becomes alternating current circuit for DC circuit.
Described wind turbine generator, solar battery and the output of diesel power generation group are connected respectively the input of integrated manipulator; The output of described integrated manipulator connects inverter and batteries; The output of described inverter connects load; The output of described batteries connects inverter; Described load is for consuming produced electric energy.
Described integrated manipulator is for monitoring the switching of generating voltage and control switch, and when generating voltage is less than predeterminated voltage, the switch of closed diesel generating set and the discharge switch of batteries, make diesel generating set work, and makes batteries electric discharge; When generating voltage is not less than predeterminated voltage, disconnect the switch of generating set and the discharge switch of batteries, diesel generating set is quit work, and make wind turbine generator and the unnecessary generating of solar battery can store batteries into.
Described integrated manipulator is wind and optical energy integrated integrated manipulator.
Wind turbine generator, solar battery, diesel generating set are connected to integrated manipulator jointly, when wind energy and sun the subject of knowledge and the object of knowledge electricity can not meet loading demand, by integrated manipulator automatic transfer switch, diesel generating set is started working, and the electric energy more than needed being stored in batteries is discharged, by inverter, convert alternating current to, make load obtain continual and steady supply of electric power.
Beneficial effect: the wind-light-diesel that the utility model provides holds micro-grid power generation system, solar energy and wind energy and diesel engine generator are carried out to organic combination, when wind energy and solar power generation abundance can guarantee supply of electric power, diesel generating set is not worked, the electric power more than needed that wind energy and sun the subject of knowledge and the object of knowledge produce simultaneously can store batteries into, avoids waste; When wind energy and sun the subject of knowledge and the object of knowledge electricity can not meet supply of electric power, by integrated manipulator, automatically switch, make batteries discharge the electric energy more than needed of storage, diesel generating set is started working simultaneously, to guarantee continual and steady electric power output.The utility model, can guarantee in different seasons and period, making full use of of solar energy and wind energy, improve the utilization ratio of new forms of energy, again can be when natural conditions be not enough, guarantee continuation and the stability of electric power output, the common generating of mutual supplement with each other's advantages that realizes new forms of energy and traditional energy meets user's life, productive power demand.
