In wind photovoltaic hybrid movable base station intelligent power supply system, wind turbine generator belongs to the part that electric energy produces, and is mainly made up of wind energy conversion system, transmission mechanism and generator etc.

Generator is being born the process of mechanical energy to electric energy conversion in wind generator system, and being specially wind energy conversion system is mechanical energy by wind energy transformation, and transmission mechanism transmits mechanical energy, and generator is converted into electric energy mechanical energy.It directly affects performance, efficiency and the power supply quality of this transfer process.Therefore, selecting that reliability is high, efficiency is high, control and the good generator system of power supply performance, is a vital task of wind power generation work.Generator in Mini-type wind/solar hybrid generally has three-phase permanent synchronous generator, DC generator, electromagnetic AC generator, claw-pole type generator, reluctance type generator and inductor-type generator etc.

Along with the technical development of permanent magnetic material, permanent magnetic material magnetic property improves greatly, in addition three-phase permanent synchronous generator small volume and low price, there is no excitation winding, do not consume exciting power, thereby have higher efficiency, reversing arrangement and brush are saved, reliability is high, and stator iron loss and mechanical loss are relatively little, long service life, in addition, starting reactance square is for miniature, one of important indicator of the low speed permanent magnet generator of small wind device, it directly affects starting performance and the low cruise performance of wind energy conversion system, in order to reduce the starting reactance square of tangential permanent magnetic generator, must select the suitable number of teeth, number of poles coordinates, adopt every utmost point fractional-slot design, the denominator value of fractional-slot is larger, air-gap permeance is got over evenly with rotor-position, starting reactance square is also just less, adopt the small-sized wind power generator group of magneto alternator generally to adopt direct-drive type structure, in order to regulate its power output, can separately add output control circuit, realize by controller, therefore use in the present embodiment three-phase permanent synchronous generator.

Three-phase permanent synchronous generator hardware main circuit structure as shown in Figure 3.The three-phase alternating current of wind-driven generator output meets U, V, W, after control rectifier rectification and capacitor C 0 voltage stabilizing, does not charge a battery through three-phase.In figure, SP, SN are respectively the positive and negative electrode binding post of solar panel, D1 is anti-reverse charging diode, its effect is to prevent that the commutating voltage of battery tension and wind-driven generator from, to the reverse filling of solar battery array, guaranteeing the unilateral conduction of solar cell.R0 is the electric power generation unloading resistance of wind-driven generator, and in the time that wind speed is too high, wind-driven generator output voltage is greater than accumulator super-charge voltage, and it is open-minded that Q3 is controlled in single-chip microcomputer output pulse (PWM), and unnecessary energy is consumed on electric power generation unloading resistance, thus protection storage battery.Diode D2 and fuse F1 are in order to prevent that storage battery from connecing instead, and when storage battery connects inverse time, storage battery forms short-circuit loop by D2 and F1, burn fuse and cut off circuit, thus protection controller and storage battery.Main circuit mid portion is the Buck type DC/DC converter of two output-parallels, the switching loss producing because of overvoltage, du/dt overcurrent, di/dt in order to suppress MOSFET pipe, and DC/DC converter using has the Buck converter of buffer circuit.

Solar photovoltaic cell panel is another part that produces electric energy in wind photovoltaic hybrid movable base station intelligent power supply system, and it is responsible for converting solar energy to electric energy.

Solar photovoltaic cell panel is that electric energy has three main process by light energy conversion:

First, solar panel absorbs after the photon of certain energy, produces electron-hole pair in semiconductor, becomes " photo-generated carrier ", and both is electrically contrary; Then, electrically contrary photo-generated carrier is tied by semiconductor P-N the electrostatic field being produced and is separated; Finally, photo-generated carrier electronics and hole are collected by the both positive and negative polarity of solar cell respectively, and in external circuit generation current, thereby obtain electric energy.

The output of photovoltaic battery panel is nonlinear, and output is subject to the impact of intensity of illumination, temperature and load characteristic.The output voltage of regulating and controlling photovoltaic cell, makes it be operated in maximum power point voltage place in real time, thereby ensures that the power output of solar photovoltaic cell panel keeps maximum, and this control method is exactly MPPT maximum power point tracking method.There are at present two kinds of MPPT maximum power point tracking control strategies that photovoltaic generation is conventional, be constant voltage control method (Constant Voltage Tracking-CVT and disturbance observation (Perturb and Observe methods, P & O).

1) constant voltage control method

At a certain temperature, the maximum power point of photovoltaic battery panel under different illumination intensity is always approximate near a certain constant magnitude of voltage Vm, is Pm at the power of this point cell panel output.Therefore, only need to be by the coupling of load impedance, make output voltage stabilization at photovoltaic battery panel near Vm, just can realize maximum power point control.But under same intensity of illumination, maximum power point is also subject to the impact of temperature, that is to say, under different temperatures, the value of Vm is not a definite value, especially in the situation that variations in temperature is larger, this impact is more obvious, and this is also the defect place of this control method.Because this method control is fairly simple, easily realize, not therefore clearly in the situation that in variations in temperature, be often used.

2) disturbance observation

The thought of disturbance observation is similar with the maximum power point search method in the utility model, is one of at present conventional MPPT control method.Its principle is often to increase at regular intervals or reduce photovoltaic cell terminal voltage, and well is observed power change direction thereafter, decides next step control signal.The great advantage of this control method is that it is simple in structure, and measured parameter is few.Its shortcoming is due to the existence that has all the time " disturbance ", and its output has certain minor fluctuations, in maximal power tracing process, will cause power loss slightly, same in order to increase the precision of control, can adopt variable step disturbance observation.

Above-mentioned two kinds of control methods respectively have pluses and minuses, and the former controls simply, but temperature influence is larger, and the latter can follow the tracks of the maximum power point under different temperatures, but have fluctuation, are unfavorable for the stable of system.According to actual needs, the utility model combines the two, control thinking is: Vm first based on experience value, adopts CVT to start, because CVT method has good starting characteristic, then adopt disturbance observation, obtain maximum power point, so just obtain the Vm at a maximum power point place, because temperature can not be suddenlyd change, therefore within a certain period of time, the Vm of photovoltaic generating system keeps inconvenience substantially; Then adopt CVT method, by the output voltage control of system near the Vm recording.After a period of time, repeat above-mentioned steps, can realize the control of photovoltaic generating system maximum power output.

Storage battery is requisite auxiliary equipment in wind photovoltaic hybrid movable base station intelligent power supply system.Storage battery mainly plays three effects in whole electricity generation system: the one, and energy storage, because natural wind and sunshine are unsettled, under the condition of wind, sunshine abundance, can store unnecessary electric energy after supply load, the in the situation that of not good at wind-force, sunshine, can export electric energy to load; The 2nd, voltage stabilizing, the rotating speed of wind-driven generator and the size of output voltage depend on the size with wind speed, and because the variation of natural wind is very big, randomness is strong, makes voltage domain of walker very large, regulates by storage battery, and it is stable that supply power voltage can keep; The 3rd, wind light mutual complementing, wind power generation and photovoltaic generation are two stand alone generating systems, they have very big difference in generating intensity sometime, utilize storage battery the electric energy of the two generation can be combined, and realize the complementation of the two.Whether battery capacity configuration is reasonable, and very large on the technical-economic index impact of small-sized wind light mutual complementing power generation, capacity selects little, and system is sent unnecessary electric weight and be can not get storing; Capacity selects large, increases first investment, the second storage battery state in undercharge for a long time, efficiency and life-span that directly impact is used.In conventional storage battery, mainly contain lead acid accumulator, alkaline nickel storage battery and iron-nickel storage battery.Wherein cheap, the dependable performance, safe of lead acid accumulator, and technical constantly progressive and perfect.

Overcharging and crossing of storage battery battery put and all can be affected its life-span, when battery discharging serious, when brownout, can damage equally storage battery, at this moment the strategy that the utility model is taked is to disconnect discharge loop by relay, in the time that voltage is replied, then reopens discharge loop.For keeping system steady operation, the utility model also adopts the stagnant ring control of battery discharging voltage, prevents from that storage battery from crossing to put.

In wind photovoltaic hybrid movable base station intelligent power supply system, translation interface is realized the functions such as long-range transparent transmission (unrestricted transfer of data), note transmission, phonetic dialing.External protocol interface has: 1 tunnel output IO interface, zigbbe, infrared interface are inputted in network interface, 232,485 agreement serial ports, CDMA2000 3G network interface, 2 tunnels, the User Defined interface that simultaneously provides support, according to the corresponding interface mode of user's Demand Design.

Built-in data interconnecting module, importing network interface into data according to combination is exported by different modes such as 3G network, 232 serial ports, IO mouths, control thereby realize more flexibly, taking network interface access IP camera as example: IP network camera is in the market realized the transmission of video flowing by configuration relevant information, data can realize transparent transmission by 3G module through intelligent multiprotocol conversion part, realize remote transmission, finally reach wireless screen flow transmission, also can forward PC terminal to by 232 serial ports, finally realize many equipment by repeater, local area network (LAN) and check simultaneously.

The multichannel interface providing provides great convenient for the mutual transmission between terminal equipment, in the situation that distinct interface terminal equipment changes, according to the different transmission-receiving functions of stirring combination and just can realize distinct interface.

Network interface access device does data input by mixed-media network modules mixed-media, and the external input information of PC, after being processed by CPU, through serial ports or the output of IO mouth, is controlled each interface equipment thereby realize PC, and implemented to control the operation situation of each interface equipment.

IO2 road input interface, can external intelligent switch system, the total lock relay of large electric appliances equipment, and controlling in real time IO state is equipment running status, and state information is fed back to PC terminal in time to add up in time, to process.
