Summary of the invention
The objective of the invention is to overcome the shortcoming of above-mentioned prior art, under the condition of the running water system that possesses certain wind-force, illumination condition and central water supply, design one substantially need not external complement electric power system in solar energy, tap water energy, wind energy or the complementary sets of power supply, realization is independent of solar power plant, wind energy generating plant, running water generating equipment, electric energy storage device outside the existing electric power system, and by inverter circuit the general power consumption equipment of family is powered.
The object of the present invention is achieved like this, the family expenses new energy source energy-saving system of a kind of solar energy, tap water energy, wind energy complementary centrally connected power supply, it is characterized in that being provided with device of solar generating, wind electricity generating system, running water Blast Furnace Top Gas Recovery Turbine Unit (TRT), control rectifying device, inverter, electric energy storage device, civil power access device, device of solar generating, wind electricity generating system, tap water can connect control rectifying device and electric energy storage device respectively by device, and electric energy storage device realizes that by inverter DC/AC conversion back powers to power consumption equipment.
Described device of solar generating can be any in monocrystalline silicon, polysilicon, the non-crystal silicon solar energy photovoltaic cell, and the selection of photovoltaic group or photovoltaic array is according to location solar radiation amount and system's scene Water Resources Allocation situation decision.Usually generated output is selected according to 300-1000W.
Described wind electricity generating system can be that alternating current generator also can be a DC generator, DC generator does not then need rectification function in the device controller in this way, ac power generation can be any in single-phase or the three-phase, corresponding the adjusting of rectification circuit in the corresponding controller.Usually according to the region annual mean wind speed, generated output is chosen in 200-600W.
Described running water Blast Furnace Top Gas Recovery Turbine Unit (TRT) can be a household tap water miniature power generating device of having applied for that utility model patent is related, and its output voltage range is for exchanging 10-25V.Its generated output can be chosen in 100-300W.
Described electric energy storage device is maintenance-free lead accumulator group or maintenance-free cadmium nickel batteries.DC bus-bar voltage is selected 12V or 24V.
Described control rectifying device comprises that a controller for solar, a wind energy controller and a tap water can controllers.The effect of wind energy controller mainly contains charging, prevent that storage battery from overcharging, prevent the storage battery overdischarge, provide the drain charge path to generator, promptly charge to storage battery after by the rectifying tube in the controller rectification at alternating current that generator sends, after lead-acid accumulator is full of electricity, controller control automatically continues large current charge, avoid causing storage battery to overcharge, influence storage battery useful life, and lead-acid accumulator is when externally discharging into its rated capacity of 70%, controller control automatically stops external discharge, avoid over-discharge can, cause that the storage battery capacity is expendable to go down even lost efficacy; After storage battery was full of, the electricity that wind-driven generator sends can not offer storage battery, and control system disconnects charging circuit, and at this moment controller can provide a resistance drain charge device to generator automatically, avoids the rotating speed of generator to raise at double, even causes driving.The effect of controller for solar mainly contains and overcharges, crosses and put protection; promptly realize the charge and discharge Automatic Control of whole system; when accumulator electric-quantity is full of, cut off the solar cell large current charge automatically, change trickle charge into, when accumulator electric-quantity is not enough, report to the police and cut-out output.The function and the wind energy controller basically identical of tap water energy controller.
Three controllers all have the DC bus-bar voltage monitoring function, are lower than 80% o'clock of rated voltage in DC bus-bar voltage, start the civil power access device and insert civil power automatically and keep stable operation.Three controllers all are provided with and prevent that storage battery is to Blast Furnace Top Gas Recovery Turbine Unit (TRT) reverse charge function.Three controllers also can be assembled in the device, but each other must be independent separately.
Described power consumption equipment comprises equipment such as television set commonly used, refrigerator, illuminating lamp, computer, washing machine, electric fan.
Described inverter is that apparent power is at the DC/AC of 1.5-3.5KVA conversion equipment.
Among the present invention, under the normal condition, the required electric energy of whole system need not extraneous supplementary power by device of solar generating, wind electricity generating system, running water Blast Furnace Top Gas Recovery Turbine Unit (TRT) provide jointly.During a certain or two kinds of energy shortages, can provide electric power when the external world by the Blast Furnace Top Gas Recovery Turbine Unit (TRT) of remainder, electric energy storage is earlier gone into electric energy storage device, again by electric energy storage device by the DC/AC conversion to power devices.When the honourable water resources complementary combinations state of appearance extremely worsens, detect by DC bus-bar voltage, insert commercial power interface automatically and charge temporarily, to guarantee that system reaches energy saving and reliability is neglected neither.
The domestic energy-saving electric power system of solar energy, tap water energy, wind energy complementary centrally connected power supply is powered to household equipment, need not power outside the system under the normal condition; But consider controlled investment, keep the stability of a system, factor such as enhanced system adaptability that equipment such as more powerful air-conditioning, warmer are not recommended to insert in principle, still pass through mains-supplied.The fabulous area of scene water resources condition can be considered equipment access systems such as air-conditioning, warmers.
