Abstract
A solar centralized power supply system comprises an autotransformer, a relay, a solar battery, a storage battery and a controller, wherein the solar battery, the autotransformer and the storage battery are all connected with the controller; the solar centralized power supply system is characterized in that electricity is supplied by solar energy to the storage battery; when a user uses electricity, the storage battery supplies power through the controller; if the electricity of the storage battery runs out, the storage battery is closed by the controller; a relay coil is disconnected and actuated, the autotransformer which is connected with electric supply is connected through a contact of the relay; and the electric supply is converted to provide power supply for a user. The solar centralized power supply system can output electricity to the user under various conditions, so that the phenomenon of power failure is not caused in the running course.
Description
Technical field
The utility model relates to a kind of solar energy centrally connected power supply system, and further relating to a kind of is to close by solar cell or with wind power generation and the many assembly of civil power to form micro power network.
Background technology
Solar electric power supply system is made up of solar module, controller for solar, storage battery (group).As out-put supply is alternating current 220V or 110V, can also dispose inverter by actual needs.Acting as of each several part: (1) solar module: solar module is the core in the solar electric power supply system, also is to be worth the highest part in the solar electric power supply system.Its effect is that the emittance with the sun is converted to electric energy, or is sent in the storage battery and stores, or promotes loaded work piece.The quality of solar module and cost will directly determine the quality and the cost of whole system.(2) controller for solar: the effect of controller for solar is a control whole system operation state, and storage battery is played the effect of additives for overcharge protection, over.In the bigger place of the temperature difference, qualified controller also should possess the function of temperature-compensating.Other additional functions such as light-operated switch, time switch all should be the options of controller.(3) storage battery: be generally lead-acid battery, in the little microsystem, also available Ni-MH battery, nickel-cadmium cell or lithium battery.Its effect is the electrical power storage of when illumination is arranged solar module being confessed, and it's time to needs to discharge again.
The shortcoming of solar electric power supply system is can't power under the insufficient situation of illumination, and power-on time can't guarantee for a long time, and the solar energy rate for incorporation into the power network is more expensive at present.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model aims to provide also stand-by power supply of a kind of area that civil power can be arranged in addition, makes the user that exports to that electric power system can be stable under various conditions, and the unlikely power failure phenomenon that causes is in operation.Unite by solar cell, wind-driven generator in addition and generate electricity, storage battery is charged, discharges, middle process controller discharges and recharges control, realizes comprehensive uninterrupted power supply.
The technical scheme in the invention for solving the technical problem is: a solar energy centrally connected power supply system, its system comprises autotransformer, relay, solar cell, accumulate pond and modulator, solar cell, autotransformer, accumulate pond all link to each other with modulator, wherein solar energy provides electric energy, storage battery power supply; During user power utilization, powered by controller by storage battery, if the electric energy of storage battery is owed electricity, controller cuts out storage battery, the adhesive of relay coil outage here, and the contact of relay will be connected city's piezoelectric transformer, will be converted to the user by civil power and power.
Further optimal design to the aforementioned techniques feature, wherein, described storage battery is a lead acid accumulator, single voltage is 2V, and 24 the voltage of contacting is 48V, is directly directly to supply with by battery for nearer user, for user far away is the power supply of boosting, voltage is carried out the high pressure that 48VDC is transformed into DC300V, can reduce loss like this, also can save the line footpath of electric wire.By solar cell, wind-driven generator storage battery is charged, middle process controller discharges and recharges control.The LED illuminating street lamp system of wind light mutual complementing centrally connected power supply, its power supply object is mainly LED lighting apparatus a certain zone in, but can not be interpreted as and limit its power supply near other power consumption equipments in the zone or zone.
In addition, in the area that civil power is arranged also stand-by power supply, make the user that exports to that electric power system can be stable under various conditions, the unlikely power failure phenomenon that causes is in operation.
Be converted to electric energy lighting apparatus is powered by solar energy, wind energy, need not power outside the system, be applicable to the various environment that are unfavorable for externally fed; Solar power plant, wind energy generating plant, electric energy storage device is independent, lighting apparatus need not be positioned in sunshine and the wind environment, thereby make whole illuminator can adapt to applied environment in the various underground or massifs.And because the whole generating system configuration is simple and reliable, make solar energy, wind energy and dispatch from foreign news agency form organic complementary, environment is not impacted, and the more single generation mode of degree of dependence to environment is little, whole generating capacity is compared with single generation mode and is improved a lot, reach mutually replenishing of wind energy, luminous energy, improved energy conversion efficiency, reduce cost, energy-saving and environmental protection.
