Description
Technical field
The utility model belongs to microgrid control system technical field, more particularly to a kind of exchange micro-capacitance sensor of Optimal improvements
Control system.
Background technology
The appearance of distributed power generation solves non-renewable energy resources and increasingly reduces disadvantage with large-scale power grid centrally connected power supply very well
End, although distributed power source has many good qualities, in failure, distributed power source must be cut off from network at once, and this is with regard to big
The big efficiency for limiting distributed power source plays, and distributed power source composition has then been coordinated in the appearance of microgrid well, can with it is big
Power network is incorporated into the power networks, and when bulk power grid breaks down, piconet island operation, stands alone as load power supply；Network structure is sent out in microgrid
When changing or failure, how to coordinate relation between each micro battery, under any circumstance can be to load with guarantee
Quality supply, this difficult point are exactly the crucial part of microgrid control technology；Being incorporated into the power networks for microgrid, have impact on master to a certain extent
Net quality, generate voltage pulsation, dodge side etc., requirement of this kind of sensitive equipment of computer, microprocessor to the quality of power supply
Compare it is harsh, even the Voltage Drop in several cycles will all influence the normal work of this kind equipment, to society cause it is huge
Economic loss, therefore, control and improvement to the quality of power supply are just particularly important.
Utility model content
The utility model purpose is to propose a kind of micro grid control system of Optimal improvements, to solve network knot in microgrid
When structure changes or broken down, how to coordinate relation between each micro battery, under any circumstance can be right with guarantee
The problem of load quality supply.
A kind of micro grid control system of Optimal improvements, including power distribution network, transformer, switch, converter A, load, conversion
Device B, direct grid-connected generator unit, inverter, energy storage device, electricity generation system, the power distribution network are connected with transformer, the change
Depressor connects with switch, and the switch connects the converter A, converter B, inverter, the conversion by ac bus
The device A connections load, the converter B connections direct grid-connected generator unit, the inverter fill with the energy storage
Connection is put, the energy storage device is connected with electricity generation system, and the electricity generation system is solar power system.
Further, the transformer is high frequency transformer.
Further, the switch is relay.
Further, the AC/AC converters that the converter A and converter B are.
Further, the inverter is AC/DC converters.
Further, the energy storage device is power-type energy storage device.
The beneficial effect that the utility model is compared with the prior art includes：
The micro grid control system of Optimal improvements of the present utility model is simple in construction, reasonable in design, and it is convenient to realize, uses behaviour
It is convenient to make, and can control the switching of the micro-grid connection method of operation or decoupled mode at any time by being switched at points of common connection,
Electric power system is reliable and stable, and service life length, practical, using effect is good, is easy to promote the use of.
Brief description of the drawings
