Embodiment
Field high efficiency wind and solar generation system as shown in Figure 1, wind-driven generator, wind-force electric energy rectification module and wind-force electric energy charge switch form the wind-power electricity generation major loop, and photovoltaic panel, photovoltaic electric energy rectification module and photovoltaic electric energy charge switch form the photovoltaic generation major loop.The photovoltaic discharging circuit comprises photovoltaic off-load unit and photovoltaic off-load switch, and the wind-force discharging circuit comprises wind-force off-load unit and wind-force off-load switch.Photovoltaic electric energy charge switch, wind-force electric energy charge switch and photovoltaic off-load switch are insulated gate bipolar power tube module.
SC system controller links to each other with storage battery, wind-force electric energy charge switch, photovoltaic electric energy charge switch, wind-force off-load switch and photovoltaic off-load switch respectively, and be located at wind-force electric energy rectification module respectively and link to each other with current/voltage Check point on the photovoltaic electric energy rectification module DC leadout road, control the switching of each switch according to the information of voltage of detected current/voltage information and storage battery.
In the wind-power electricity generation major loop, the mutual combination of wind-force off-load switch and deciliter action of wind-force electric energy charge switch, can realize following three kinds of modes:
1), wind-force off-load switch disconnects, wind-force electric energy charge switch closure can realize that the wind-powered electricity generation energy all enters charge in batteries;
2), wind-force off-load switch on, wind-force electric energy charge switch closure can realize that part wind-powered electricity generation energy enters charge in batteries;
3), wind-force off-load switch on, wind-force electric energy charge switch disconnects, and can stop the wind-powered electricity generation energy and enter charge in batteries, its energy all enters discharging circuit, prevents wind-driven generator " driving ";
Simultaneously, in the photovoltaic generation major loop, the combination of its off-load switch and electric energy charge switch can realize three kinds of modes that following and above-mentioned wind-power electricity generation is identical.Therefore, the combination that wind-force and photovoltaic generation are mutual, can realize following six kinds of compound modes: the one, scene is charging all; The 2nd, scene all withdraws from charging; The 3rd, wind all charges, and light partly charges; The 4th, wind all charges, and light all withdraws from charging; The 5th, light all charges, and wind partly charges, and the 6th, wind all charges, and light all withdraws from charging.
The control corresponding parameter is set in the SC system controller, comprise the charge in batteries upper limit current, wind-force off-load unit resistance, photovoltaic off-load unit resistance, (wind-force can adopt different electrical voltage points with photovoltaic to the initiation of charge voltage of storage battery cycle charging, the concrete weather conditions that is provided with according to the locality, then adopt wind low light height a little less than the wind high light, the wind low light level then adopts the high light of wind low by force), the storage battery saturation voltage (also is to stop charging voltage, equally according to local weather conditions, scene can adopt different electrical voltage points, its height setting principle is same as described above, can prevent that like this storage battery from " vacation " occurring and filling saturated situation), the slow delay time that delay time that switches between the various switches (can prevent the full disjunction or the complete closure of power circuit, improve control reliability and prevent to disturb and realize) and various combinational circuit switch.
In running, the detection battery tension that SC system controller is real-time, the wind-power electricity generation charging current, the photovoltaic generation charging current, and in SC system controller with relevant parameters by computing, select suitable charging major loop compound mode, be implemented in the process of charging, below storage battery first voltage saturation point (low spot), can realize near upper limit current storage battery being charged; Below storage battery second voltage saturation point (high point), realize being higher than the low current charge of load current, can guarantee " vacation " saturated phenomenon that storage battery occurs because of large current charge.When storage battery is filled saturatedly, wind light generation all withdraws from charging, and storage battery enters the cycle period of discharge by load equipment.After being lower than the starting voltage point of setting, enter the cycle period of scene charging once more.
In the process of operation, the disjunction in direct current power loop adopts power IGBT as switching device, and because of it has great overcurrent and withstand voltage surplus, reliability and working life can be guaranteed fully.Simultaneously in the operation control procedure, since if having time slow, charging voltage is slow, and the lasting characteristic of wind, light generating nature, in actual the use, the one, the IGBT switch can not produce frequent action, and the 2nd, when the IGBT switch motion, because the delay time that switches between compound mode and switch restriction, the synthetic gradient mode of the branch of energy in the loop realizes, the direct conversion between whole breaking and closing can not occur.
Off-load resistance and power choose rated power according to blower fan, photovoltaic panel, and local on-the-spot weather conditions chooses, half that generally is chosen for actual power power is more suitable.About choosing of the initiation of charge voltage of storage battery, saturated charging voltage point and upper limit charging current, can realize according to employed battery characteristics and on-the-spot weather conditions.
Should be pointed out that present embodiment just lists expressivity principle of the present utility model and effect are described, but not be used to limit the utility model.Any personnel that are familiar with this technology all can make amendment to the foregoing description under spirit of the present utility model and scope.Therefore, rights protection scope of the present utility model should be listed as claims.
