Accompanying drawing explanation
Fig. 1 is the structural representation of multi-energy complementation hair long electric system of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As shown in Figure 1, multi-energy complementation hair long electric system of the present invention, comprises inverter, controller, batteries, solar components array, wind-driven generator, diesel engine generator and other energy generator groups as stand-by power supply.Described other energy generator groups can be geothermal energy electrification component and/or tidal power machine, can be also other.Solar components array, wind-driven generator, diesel engine generator, other energy generator groups are all connected with the input of inverter; Controller is connected with inverter; The output of inverter is connected with batteries, and the output of inverter is also for being connected with load.
Solar cell array is the array being connected and composed by some solar module series and parallels.In the time having solar radiation, solar cell array, to load supplying, provides some electrical power storage in storage battery simultaneously.The power of solar cell array, need determine according to the power consumption situation of the photoelectric conversion efficiency of the global solar radiation amount with on-the-spot, solar module and electrical installation used.
Wind-driven generator preferably adopts vertical axis aerogenerator, and wind wheel rotating shaft and ground in vertical state, are not affected by wind direction, need not tuning to wind, simplify the structure greatly, and generator is arranged on the bottom of bearing support, convenient management.Wind speed reaches after starting wind velocity, and wind wheel starts to rotate, and drives generator to start generating, exports electric energy powering load and charges a battery.In the time that wind speed exceedes cut-off wind speed, wind-driven generator makes wind-driven generator at certain rotating speed limit inferior operation or the row of stopping transport by mechanical speed limiting mechanism, to guarantee that wind-driven generator is unlikely to damage.
The energy storage device of multi-energy complementation hair long electric system of the present invention is mainly storage battery.Storage battery is long-term work under floating charge state conventionally, and its electric flux is than much bigger with the required electric flux of electric loading, and most time is in shallow discharge state.All the time according to night or when rainy weather and calm weather, storage battery is to load supplying.In addition, in the time that load has short time pulse power consumption, regenerative resource may not meet the required whole electric energy of load, and at this moment, storage battery also will be given supplementary power.
Inverter is also vitals of the present invention.In multi-energy complementation hair long electric system of the present invention, wind-powered electricity generation unit (separate unit or many, after rectification), photovoltaic array carry out floating charge to storage battery, and simultaneously to inverter power supply, direct current is through the backward AC load power supply of inversion.In the time that battery tension is too low or the output of wind-powered electricity generation, electro-optical system can not meet load, diesel engine generator starting is for charge in batteries or load is switched to diesel engine generator from inverter.Consider that multi-energy complementation hair long electric system cost compare of the present invention is high, and it generally has the long period to be operated in zero load or light condition, therefore inverter used should have higher conversion efficiency, particularly zero load and light-load efficiency.Inverter technology in system can adopt SPWM control technology, realizes the maximal power tracing control to wind power generation and photovoltaic generating system.Thereby realize following function: (1) guarantees wind-powered electricity generation, photoelectricity is to charge in batteries and power to the load, and metering, detection and the demonstration of various call parameters are provided simultaneously.(2) in the time of overcharge of a battery or overdischarge, report to the police or line disconnection automatically, protection storage battery.(3) provide on demand high-precision constant voltage or constant current; (4) in the time that storage battery has fault, can automatically switch, connect standby battery, with the normal electricity consumption of proof load;
Adopt advanced electron electric power building block technique, the power module of unique forceful electric power and the combination of light-current system, interference and the conduction quality of assurance system to electrical network, is guaranteed the power quality of electrical network.
Controller can adopt programmable controller (PLC) and man-machine interface composition, utilizes the programming configuration software of PLC, can the powerful control action of practical function.PLC and man-machine interface are used Ethernet to be connected, and with the communicating by letter of host computer.Man-machine interface, for measurement parameter and the state of a control of display system, also can be used for the manual control to electricity generation system.Host computer can show the running status of electricity generation system, and setup control parameter.By Ethernet interface, can, by electricity generation system accessing Internet, realize networking remote monitoring.
Diesel engine generator is as stand-by power supply, in the situation that multi-energy complementation hair long electric system of the present invention cannot normally be worked, (as continuous overcast and rainy or calm weather etc.) powers to the load, diesel engine is also to storage battery boost charge, to prevent that storage battery from reducing useful life in power shortage state for a long time simultaneously.
Multi-energy complementation wind-light-diesel hair long electric system is intended to realize solar energy, wind energy and fossil energy integrated complementary, builds up integrated container power station, reaches the efficient object of utilizing of various energy resources.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
