Description
Technical field
The utility model relates to miniature hydro-power generation field, is specifically related to adopt switch reluctance generator to be the generating and transmitting system of hydroelectric generator.
Background technology
Hydroelectric power generation is a kind of clean, green renewable energy power generation form for mark; Current hydroelectric generator is to adopt synchronous alternating-current generator.
And more confidential than synchronous generator simply many in switch reluctance generator structure, brushless on its rotor, without winding, without permanent magnet, mean the maintenance that higher reliability is less and lower installation cost and equipment purchase cost; And in running, switch reluctance generator controllable parameter is many, as turn-on angle, hold-off angle control, Current cut control, PWM controls, and can realize the control strategy of more complicated easily, controls output dc voltage and electric current flexibly;
In recent years, the research and practice about switch reluctance generator gets more and more.
Summary of the invention
According to above background technology, the utility model proposes the main generator adopting switch reluctance generator as small hydropower station, and provide its output electrical conversion systems, system configuration is simple, and reliability is high.
The technical solution of the utility model is:
Adopt the small hydropower station generating and transmitting system of switch reluctance generator, by small-sized water turbine switching magnetic-resistance electricity generation system, Power Diode Pumped D, boost converter, Inverter Station forms, its technical characteristic is, described small-sized water turbine switching magnetic-resistance electricity generation system exports direct current positive and negative end, positive terminal circuit is connected described Power Diode Pumped D, input one end of the boost converter described in negative pole connection of Power Diode Pumped D, another input of boost converter is connected with the output negative terminal of small-sized water turbine switching magnetic-resistance electricity generation system, the Inverter Station described in two outputs connections of boost converter, Inverter Station exports three-phase alternating current.
Small-sized water turbine switching magnetic-resistance electricity generation system comprises the hydraulic turbine, switch reluctance generator and controller thereof; Possess the small hydropower station of many cover small-sized water turbine switching magnetic-resistance electricity generation systems, the output of each system adopts mode in parallel.
Boost converter hoists the effect of High Level DC Voltage, to meet the needs that Inverter Station exports the alternating current of high voltage; Boost converter, according to the adjustment of the duty ratio of its internal power electronic switching tube, can change the DC voltage value that it exports.
The Main Function of Inverter Station is three-phase alternating current by the DC inverter of input.
Major technique effect of the present utility model is:
The small hydropower station generating and transmitting system of employing switch reluctance generator of the present utility model, adopt switch reluctance generator, structure is simple, firm, reduces cost and improves reliability.
Due to the pressure regulation effect of boost converter, enhance flexibility and the controllability of transmission of electricity.
The existence of Power Diode Pumped D, ensure that possible back electrical energy causes the possibility of accident when the shutdown of small-sized water turbine switching magnetic-resistance electricity generation system or fault.
Accompanying drawing explanation
Figure 1 shows that the small hydropower station generating and transmitting system structure chart of employing switch reluctance generator of the present utility model.
Embodiment
Be illustrated in figure 1 the small hydropower station generating and transmitting system structure chart adopting switch reluctance generator, small-sized water turbine switching magnetic-resistance electricity generation system completes from waterpower to galvanic conversion, after certain filtering, export to boost converter, middle Power Diode Pumped D plays the possibility prevented to small-sized water turbine switching magnetic-resistance electricity generation system feed; If many cover small-sized water turbine switching magnetic-resistance electricity generation systems, in view of the current source character of switch reluctance generator, the output of each system takes mode in parallel.
The core of boost converter is boost boost chopper main circuit, for lower direct voltage is raised, larger output voltage is obtained by the duty ratio increasing electronic power switch pipe in boost converter, to adapt to the needs that Inverter Station exports higher alternating current, if the alternating current that Inverter Station exports need be incorporated to AC network, then also need to install transformer additional and carry out isolating and boosting further.
Inverter Station is primarily of main inverter and control and protection device composition thereof.
For the small-size water pumping storage station of miniature hydro-power generation industry, system of the present utility model also the generating of hydroenergy storage station and station in the transmission of electricity stage possess application conditions.
