Background technology
Electric energy is the basic guarantee that guarantees people's normal life, working and learning.The anxiety of coal and water resources and scarcity make the electric energy day of hydroelectric power generation and thermal power generation be becoming tight.Hydroelectric power generation and thermal power generation have also brought great negative effect to environmental protection simultaneously.In order to meet mankind's normal life and requirements of one's work, safeguard harmony, the nature of biological environment, people bring into use other regenerative resources that can reuse.For this reason, solar energy is reached widely and utilizes by human development as a kind of energy of green non-pollution.
But, because solar energy can strong and weak the variation occur along with time variation, Changes in weather, thereby cause the photovoltaic module electricity generation system also to be difficult to provide stable, continual power supply.Be applied in widely the period of industry and civilian every field as the device of proof load continued power in uninterruption power source system (UPS), solar power generation unstable, apply it and be greatly limited.Therefore, current solar power generation utilize process, need to take measures to make the solar power generation can form the power-supply system of uninterrupted power supply, improve the reliability of solar electric power supply system, to guarantee the safe operation of AC load, safeguard the use safety of AC load.
Summary of the invention
In order to overcome above-mentioned technological deficiency, it is a kind of for the solar electric power supply system of uninterrupted AC power is provided that the utility model provides, guarantee the photovoltaic module long period can not generate electricity or the public electric wire net long period during dead electricity AC load can access reliable, stable uninterrupted power supply, thereby ensure the normal operation of AC load.
Solar electric power supply system described in the utility model, comprise photovoltaic module, controller for solar, energy-storage battery, inverter and AC load.Wherein, described photovoltaic module, controller for solar, energy-storage battery, inverter and AC load are electrically connected to successively, the electric energy that described photovoltaic module produces is controlled energy-storage battery is charged through controller for solar, electric energy in energy-storage battery is through the controller for solar controlled discharge, and the electric energy of its output is exported to AC load after inverter is converted to alternating current.Described inverter is preferably pure sine wave inverter.
Also comprise: (1) alternating-current controller, with public electric wire net and energy-storage battery, be electrically connected to, when not enough for the electric energy in photovoltaic module output, the civil power of controlling the public electric wire net generation is charged to energy-storage battery, (2) automatic change-over, be electrically connected to public electric wire net, inverter and AC load, for when energy-storage battery can not be powered to AC load, directly AC load powered by public electric wire net.Be connected with pressurizer between described automatic change-over and AC load, for stablizing the voltage of civil power.The electricity generation system formed thus, the power source that is formed energy-storage battery by civil power and solar power generation, can realize the uninterrupted output AC electricity of AC load, the electricity consumption that has fully guaranteed AC load is stable: the one, and by the photovoltaic module generating, energy-storage battery is charged when sunlight illumination is sufficient, and by energy-storage battery, AC load is powered; The 2nd, a little less than sunlight illumination or during night, by civil power under the control of alternating-current controller to the energy-storage battery charging, and by energy-storage battery, AC load is powered; The 3rd, in the long period, do not have sunlight illumination or energy-storage battery to damage so that while not having energy-storage battery there is no electric energy output, directly by civil power, AC load is powered.
According to Blast Furnace Top Gas Recovery Turbine Unit (TRT) described in the utility model, it is simple in structure, is convenient to processing and installs; Realized solar power generation and civil power automatic switchover, take solar power generation as main, civil power as auxiliary complemental power-generation, take full advantage of solar power generation, green energy resource and civil power are reasonably used; Realized the uninterrupted power supply to AC load, working stability, improved the reliability of power supply greatly, can steady in a long-term move.
The accompanying drawing explanation:
Fig. 1 solar power system schematic diagram described in the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further, but not as to restriction of the present utility model.
As shown in Figure 1: according to solar power system described in the utility model, comprise photovoltaic module, controller for solar, pure sine wave inverter, energy-storage battery, public electric wire net, alternating-current controller, automatic change-over, pressurizer and AC load.Wherein, described photovoltaic module, controller for solar, energy-storage battery, inverter, automatic change-over and AC load are electrically connected to successively.The electric energy that described photovoltaic module produces is controlled and automatically energy-storage battery is charged through controller for solar, electric energy in energy-storage battery is through the controller for solar controlled discharge, the electric energy of exporting is exported to AC load by automatic change-over after inverter is converted to alternating current, realizes by photovoltaic module, AC load being powered.Public electric wire net, pressurizer, automatic change-over and AC load are electrically connected to successively, realize directly AC load being powered by public electric wire net.Two kinds of supply power modes are switched by automatic change-over.When photovoltaic module has electric energy output, automatic change-over switches to inverter, and the direct current that photovoltaic module produces is exported to the AC load power supply to the energy-storage battery charging and by inverter automatically through controller for solar; When photovoltaic module does not have electric energy output, automatic change-over switches to pressurizer, by public electric wire net, directly AC load is powered.Be connected with alternating-current controller between energy-storage battery and pressurizer.When photovoltaic module does not have electric energy output, described alternating-current controller is controlled civil power provides the larger electric current that maintains to charge to energy-storage battery automatically, guarantees that energy-storage battery is all the time in full state.Even, when energy-storage battery does not have electric energy output, still can directly power by automatically switching to by civil power.
