Three Switched Reluctance GeneratorUsed in Wind Energy Converter Systems are identical system, all complete maximal wind-power tracking separately and control.
The core of electrical storage device is batteries, also comprises discharge and recharge and assists and protect and filter.
Cuk chopper circuit, by the control to electronic power switch pipe wherein, can make its output dc voltage size adjustable, to meet the requirement that inverter exports three-phase alternating current 380V voltage.
Major technique effect of the present utility model is:
Small-sized island of the present utility model switching magnetic-resistance wind power generation direct current generating and transmitting system, adopts clean reproducible wind power generation, improves the environment on island.
Because switch reluctance generator directly sends direct current, eliminate the rectification link needed for conventional wind-powered electricity generation, simplifying the structure reduces cost and improves reliability (regular alternating current generator system exports and is mostly the conversion process of AC-DC-AC).
Cuk chopper circuit simple structure, high reliability, according to the adjustment of internal power electronic switching tube duty cycle of switching, flexibly changing output dc voltage value, and input is changeable relatively, wide ranges, better meets the needs that inverter exports 380V alternating current; Also adapt to wind-powered electricity generation output valve widely, improve wind-powered electricity generation utilance.

Accompanying drawing explanation
Figure 1 shows that small-sized island of the present utility model switching magnetic-resistance wind power generation direct current generating and transmitting system structure chart.
Embodiment
Be illustrated in figure 1 small-sized island switching magnetic-resistance wind power generation direct current generating and transmitting system structure chart, three Switched Reluctance GeneratorUsed in Wind Energy Converter System parallel connections, the direct current of their output ripples, through Power Diode Pumped D to while electrical storage device charging by Cuk chopper circuit and inverter to customer power supply, after electrical storage device is full of, only to customer power supply; If because wind-force is not enough or other reasons causes Switched Reluctance GeneratorUsed in Wind Energy Converter System to interrupt generating, then by electrical storage device separately through Cuk chopper circuit and inverter to customer power supply, and the effect of Power Diode Pumped D is just to prevent Generation Side from for no reason consuming the electric energy of electrical storage device when there is this kind of situation.
Cuk chopper circuit is a kind of buck-boost type chopper circuit, simultaneously its input and output current continuity, pulse little, be beneficial to filtering; When Switched Reluctance GeneratorUsed in Wind Energy Converter System and electrical storage device send out electricity shortage, storage battery both sides voltage certainly will be caused to reduce, in order to increase operation rate, now Cuk chopper circuit works in pressure-increasning state, and by regulating the duty ratio of the electronic power switch pipe of its inside, meet the requirement exporting three-phase alternating current 380V; When Switched Reluctance GeneratorUsed in Wind Energy Converter System generating is sufficient, when electrical storage device is completely electric, Cuk chopper circuit is generally operational in step-down state, and meets the requirement exporting three-phase alternating current 380V.
Particularly point out, although the present embodiment provides is three Switched Reluctance GeneratorUsed in Wind Energy Converter System parallel connections, the situation not affecting multiple Switched Reluctance GeneratorUsed in Wind Energy Converter Systems in addition is also protection range of the present utility model.
