Plate 1, DC/AC (Direct Current/Altemating Current, the input of AC/DC, i.e. direct current, exchange output) light
Lie prostrate inverter 2, lead charcoal battery 3, BMS 4 or 7, DC/AC energy storage two way convertor 5 or 8 or 10, lithium battery 6, super capacitor 9,
Intelligent power distribution cabinet 11, power load 12, diesel generating set 13 etc. belong to primary equipment, and micro-capacitance sensor is accessed by means of communication
Energy management layer 103 simultaneously can be adjusted and controlled；Secondary device is using collection protection, observing and controlling, communication, electric energy quality monitoring, electric energy
Table meter reading, the optical fiber far function such as jump obtain the system mode and flow of power situation of micro-capacitance sensor, are energy pipe in the device of one
Manage the coordination control of layer 103, Optimized Operation provides strong support, and provide it is reliable performs operation, progress power supply, load
Switching operation.
Next the function and operation principle of each equipment in mechanical floor 101 are introduced：
(1) solar energy photovoltaic panel 1 is used as new energy unit, first converts the solar into electric energy, then pass through DC/AC light
Direct current is converted to alternating current by volt inverter 2, and is transmitted to ac bus.Solar energy photovoltaic panel and DC/AC photovoltaic DC-to-AC converters 2
Installed capacity (being also station capacity) need to be determined according to the power load situation of detailed programs.DC/AC photovoltaic DC-to-AC converters 2 are controllable
The important parameter with the voltage of record direct current photovoltaic outlet side, electric current, power and cell panel is made, can also be to inversion
The voltage of the AC of device inversion output, electric current, frequency, the major parameter such as daily generation and generated output curve are controlled
With record, and backstage EMS is uploaded to.
Solar power generation is as new clean energy resource, although a kind of pollution-free, recyclable green energy resource, due to
The irradiance fluctuations of the sun, so as to cause the output of solar power generation that there is very big randomness and fluctuation, and only possesses output
The downward regulating power of power, do not possess overload regulating power, therefore in order to ensure when solar irradiation is fluctuated and changed with loading, it is micro-
The electrical stability and the quality of power supply of power network electric power system, micro-capacitance sensor electric power system must be configured with power storage and balance energy
The energy-storage units of power.
(2) energy-storage units are made up of battery module, BMS, DC/AC energy storage two way convertor, according to the difference of power load
The different performance feature of operating mode and battery module, it can generally select three class battery modules：It is lead charcoal battery, lithium battery, super
Electric capacity.
Lead charcoal battery and lithium battery belong to chemical energy storage device, often cover energy storage device by a large amount of cells string,
Compose in parallel, it is therefore desirable to which charge and discharge of the special battery management system (BMS) to every section battery are controlled and protected；
And super capacitor is used as a kind of physics energy storage device, it is not necessary to which special BMS carries out management of charging and discharging to it.
The large-scale power load of factory and enterprise generally existing, large-scale load start-up course start work(generally within 10 seconds
Rate is 3~7 times of load power, it is therefore desirable to powerful power supply support in short-term, in view of such a demand, energy-storage units can
