Summary of the invention
The purpose of the utility model provides a kind of wind energy and solar energy complementary supply station; This supply station combines through wind energy and two kinds of generation modes of solar energy; Be electric jointly through the mains-supplied net simultaneously; Thereby slow down the restriction of natural environment greatly, guarantee the stability of wind electricity generating system power supply and device of solar generating power supply simultaneously, the useful life that need strengthen batteries in addition power generation stabilization property.
According to above-mentioned utility model purpose, the utility model provides a kind of wind energy and solar energy complementary electric power system, it is connected with at least one load, and said wind energy and solar energy complementary electric power system comprises:
One wind electricity generating system, it converts wind energy into electric energy output;
One device of solar generating, it is electric energy output with solar energy converting;
One batteries;
One wind light mutual complementing controller; It is connected respectively with the output of said wind electricity generating system and the output of device of solar generating; And be connected shutoff and connection that said wind light mutual complementing controller control wind electricity generating system and device of solar generating charge to batteries with said batteries;
One inverter; It is connected with said batteries through the wind light mutual complementing controller; Said wind light mutual complementing controller control batteries is exported after the direct current that said inverter is exported batteries converts alternating current into to the shutoff and the connection of inverter output DC;
One transducer; An one of which input is connected with said inverter; Its another input is connected with the mains-supplied net; The output of said transducer is connected with said at least one load, and said transducer also is connected with said wind light mutual complementing controller, and wind light mutual complementing controller control transformation device switches ground the alternating current of said inverter output or the alternating current of mains-supplied net output are transferred to said at least one load.
The described wind energy and solar energy complementary electric power system of the utility model combines wind power generation and solar power generation, and through the wind light mutual complementing controller batteries is charged.When the batteries reserve of electricity is sufficient, give inverter by wind light mutual complementing controller control batteries with the electric energy transmitting that stores, export to load after converting alternating current into by inverter; When the batteries reserve of electricity is low when needing charging, wind light mutual complementing controller control transformation device cuts off the path of batteries to the inverter transmission of electricity, and the control transformation device switches to the state that the mains-supplied net powers to the load simultaneously; After treating that battery charging is accomplished, wind light mutual complementing controller control batteries continues to the inverter output DC, and the control transformation device switches to the state that inverter powers to the load simultaneously.
The described technical scheme of the utility model combines through wind power generation and solar power generation; Make that wind power generation and solar power generation can effective supplements: natural wind is big when cloudy day and rainy day; The radiationless power of sunlight, the electric energy efficiency of wind power generation plant generating is high; When fine natural wind a little less than, big solar irradiation power is strong, the electric energy efficiency of solar battery group generating is high.Therefore, adopt wind-force and solar energy mixed power generation can obtain the natural energy to greatest extent, thereby remedied deficiency separately.
In addition, the described technical scheme of the utility model also adopts closing and connecting of wind light mutual complementing controller control battery charging and discharge, and the switching of batteries power supply and the power supply of mains-supplied net.When charging voltage during greater than the over-charge protective voltage of batteries, controller control is not charged to batteries or is stopped charging; When charging voltage was put protection voltage less than the mistake of batteries, controller was controlled battery charging.In addition; Whether the wind light mutual complementing controller also is in charged state according to batteries; Control by batteries still to come load is supplied power: when batteries is in charged state by the mains-supplied net; Wind light mutual complementing controller control transformation device cuts off batteries to the inverter path of transmitting electricity, and the control transformation device switches to the mains-supplied net load is supplied power simultaneously; When batteries was not in charged state, wind light mutual complementing controller control transformation device cut off mains-supplied net transmission of electricity path, connected batteries transmission of electricity path, thereby by batteries load was supplied power.
The described wind energy and solar energy complementary electric power system of the utility model; Combine through wind energy and two kinds of generation modes of solar energy; And be electric jointly through mains-supplied net and batteries; Thereby slowed down the restriction of natural environment greatly, guaranteed the stability of wind electricity generating system power supply and device of solar generating power supply simultaneously, the useful life that has strengthened batteries in addition power generation stabilization property.
