Abstract
The utility model discloses a charge controller with a direct-current-side voltage limiting function for a small wind power generation system. The charge controller comprises a rectification circuit and a direct current side circuit, wherein the direct current side circuit comprises an unloading load, an electromagnetic switch, a reverse-charge-resisting diode and a PLC (programmable logic control) singlechip control system which are connected with one another in series to form a circuit connected in parallel with the rectification circuit. Compared with the conventional charge controller for the small wind power generation system, the charge controller disclosed by the utility model has the advantages of being stable and reliable in operation and reducing the probability of faults. According to the utility model, the danger of breaking a digital circuit in the controller by high voltage pulse is effectively prevented, so that the service life of a generator set is prolonged, and the power generation efficiency of the generator set is enhanced, and the market competitiveness of the generator set is improved.
Description
Technical field:
The utility model relates to a kind of charge controller, relates in particular to a kind of miniature wind power generation system charge controller with DC side pressure limiting function.
Background technology:
Traditional miniature wind power generation system comprises small-sized wind power generator, charge controller and storage battery three parts.Small-size wind power-generating has been brought into play important effect on the electrical problem that solves the sparsely populated population in outlying district.Though present performance with wind generator system increases from net type family, on reliability, still has certain problem.Charge a battery behind the three-phase alternating current electric rectification that traditional charge controller sends wind-driven generator, and do not notice the high-voltage pulse that DC side occurs after the rectification, it is one of key factor that influences system reliability that its DC side produces overvoltage.
When storage battery broke off with being connected of system, system's dc voltage also can produce very high spike, and has very big energy, if the charge controller DC break down voltage is lower than the spike peak value of system's dc voltage then can causes damage.In addition, miniature wind power generation system is in course of normal operation, if be in the PWM control stage; Promptly alternately charge and the off-load stage, system's dc voltage can produce spike, though these pulses are because the absorption of storage battery; There is not too big energy; But can have a strong impact on the operate as normal of charge controller digital circuit, therefore, when the design charge controller, should attach the importance.
The utility model content:
The purpose of the utility model is to provide a kind of a kind of miniature wind power generation system charge controller with DC side pressure limiting function that solves an above-mentioned difficult problem.
The utility model is implemented by following technical scheme: the miniature wind power generation system charge controller with DC side pressure limiting function; It comprises rectification circuit and DC side circuit; Said DC side circuit comprises that off-load load, electromagnetic switch, counnter attack fill diode and PLC single-chip computer control system; Wherein, diode is filled in said off-load load, said electromagnetic switch, said counnter attack, said PLC single-chip computer control system is composed in series the loop, and parallelly connected with said rectification circuit.
The advantage of the utility model: compare with traditional miniature wind power generation system charge controller, stable, reliable, the out of order probability of charge controller that has DC side pressure limiting function reduces.The danger of effectively having avoided the digital circuit in the controller to be damaged by high-voltage pulse, and then improved the useful life of unit and the generating efficiency of unit, improved the market competitiveness.
Description of drawings:
Fig. 1 is that the circuit of the utility model connects block diagram.
Fig. 2 is the use principle sketch of the utility model.
Embodiment: as shown in Figure 1; Miniature wind power generation system charge controller with DC side pressure limiting function; It comprises rectification circuit 1 and DC side circuit 2, and DC side circuit 2 comprises that off-load load 3, electromagnetic switch 4, counnter attack fill diode 5 and PLC single-chip computer control system 6, wherein; Diode 5 is filled in off-load load 3, electromagnetic switch 4, counnter attack, PLC single-chip computer control system 6 is composed in series the loop, and parallelly connected with rectification circuit 1.
Operation principle:
As shown in Figure 2, the three-phase alternating current that wind-driven generator 7 sends at first inserts the rectification circuit 1 of charge controller, through behind the rectification circuit 1; Occur direct current in the controller, the part after the rectification circuit 1 before the storage battery 8 is a DC side, because various improper operations; For example, break off being connected of storage battery and charger, high-voltage pulse can appear in DC side moment; These high-voltage pulses can damage in the controller other digital circuit, and PLC single-chip computer control system 6 will sample these high-voltage pulse signals, send control signal and give electromagnetic switch 4; Let the shut-off circuit conducting, like this high-voltage pulse just along circuitry consumes in off-load load 3; On the contrary, ifs circuit mesohigh blackout, PLC single-chip computer control system 6 just sends cut-off signals, and electromagnetic switch 4 is just turn-offed.It is to prevent that storage battery 8 from flowing backwards, and impacts to charge controller that diode 5 is filled in the circuit counnter attack.
