Background technology
DC power system is applied to waterpower, thermal power plant; all kinds of transformer station and other use the user of DC equipment, for giving signalling arrangement, protection, automatics, emergency lighting, emergency power supply and circuit breaker divides, closing operation provides DC power supply power-supply device.Direct current system is an independently power supply, and it not by the impact of generator, station service and system operation mode, and when outside alternating current interrupts, ensures the visual plant being continued to provide DC power supply by back-up source-storage battery.Having many uses of DC power system is general; be applied to waterpower, thermal power plant; user's (as power plant, transformer station, power distribution station, petrochemical industry, iron and steel, electric railway, real estate etc.) of all kinds of transformer station and other use DC equipment; for signalling arrangement, protection, automatics, emergency lighting and circuit breaker divide, closing operation provides DC power supply; it is widely used in Office of the Telecommunications Authority, computer floor, hospital, mine, hotel too; and the reliable emergency power supply of skyscraper, purposes is very extensive.
Direct current can be powered by AC power, also can send direct current by solar energy and power, but the output of simple solar energy is comparatively large by the impact of weather, and cannot generate electricity evening.Therefore solar cell and AC network are combinationally used and make up described unsteadiness.But electrical network is very unbalanced at the load of different period every day, and daytime, peak period, power consumption was higher, and electricity price is higher, and evening, low-valley interval power consumption was lower, electricity price is lower simultaneously.If by national grid alternating current during low ebb in evening and daytime solar cell combine and use, power consumption during peak of power consumption can not only being cut down, when meeting normal power supply, very large economic benefit can be brought simultaneously.
Summary of the invention
The utility model provides a kind of DC power supply system to solve deficiency of the prior art, according to electricity price gradient, electrical power storage when electricity price is lower is got up, the green energy resource of sunlight is introduced electric power system simultaneously, solve the problem that simple grid charging electricity can not supply for a long time, electrical network when utilizing electricity price low and solar energy organically combine and charge to battery pack cabinet, optimize the service behaviour of battery pack cabinet.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of power supply system of DC source, comprises battery pack cabinet, and the electrical power storage that national grid alternating current and solar modules are produced also is converted to regulation direct current;
Integral type controller, described integral type controller controls the charge mode of battery pack cabinet;
National grid, is charged to battery pack cabinet by integral type controller;
Solar modules, is charged to battery pack cabinet by integral type controller;
Described national grid and solar modules are connected with battery pack cabinet respectively by integral type controller charges, and is connected powers after described battery pack cabinet charging with power-using body;
Wherein, described integral type controller controls the charge mode of battery pack cabinet according to electricity price and weather, when there being sunlight, selects to be charged to battery pack cabinet by solar modules; When electricity price is low, start national grid to charge to battery pack cabinet, electrical network when utilizing electricity price low and solar energy organically combine and charge to battery pack cabinet, optimize the service behaviour of battery pack cabinet, bring very large economic benefit, alleviate power tense degree during peak of power consumption simultaneously.
As a kind of preferred version of power supply system of DC source described in the utility model, also comprise monitoring module, monitoring module is connected with integral type controller, the electricity of monitoring module monitoring battery pack cabinet, when the high and battery pack cabinet electricity of electricity price is higher than discharge threshold, national grid does not charge to battery pack cabinet; After the high and battery pack cabinet electricity of electricity price is lower than discharge threshold, starts national grid and battery pack cabinet is charged.Further optimization power supply system of DC source, avoids the deficiency due to solar power generation to cause battery pack cabinet electricity use up and circut breaking occurs.
As a kind of preferred version of power supply system of DC source described in the utility model, described battery pack cabinet also has batter life extender, batter life extender is connected with battery pack cabinet, and batter life extender compensates battery pack cabinet, improves the useful life of battery pack cabinet.
As a kind of preferred version of power supply system of DC source described in the utility model, described electric power system also comprises monitoring device, monitoring device is connected with battery pack cabinet and integral type controller respectively, Real-Time Monitoring battery pack cabinet parameter information, the parameter information of monitoring comprise in the internal resistance of cell, real-time current, voltage and temperature any one or a few.
Beneficial effect:
Power supply system of DC source described in the utility model, according to electricity price gradient, electrical power storage when electricity price is lower is got up, the green energy resource of sunlight is introduced electric power system simultaneously, solve the problem that simple grid charging electricity can not supply for a long time, electrical network when utilizing electricity price low and solar energy organically combine and charge to battery pack cabinet, optimize the service behaviour of battery pack cabinet.
