Middle three levels of decision-making level.Its mechanical floor, distributed AC servo system layer are integrated in prefabricated cabin, and centralized decision-making layer is set according to actual demand
It puts in somewhere secondary device room or monitoring room outside prefabricated cabin, can also be not provided with.All kinds of measure and control devices are the device of mechanical floor,
The portable microgrid monitoring system of distributed AC servo system layer will be sent on all kinds of appliance arrangement status datas and operation data, it is portable
Microgrid monitoring system can be considered the brain of entire portable micro-grid system, realize to the panorama monitoring analysis of microgrid data and energy
The formulation of management strategy is measured, is micro-capacitance sensor control main website layer.The portable microgrid monitoring system of distributed AC servo system layer completes energy
After the formulation of management strategy, control command is issued to all kinds of measure and control devices.
Its major function of centralized decision-making layer includes：1）The monitoring of multizone randomness power supply real time data and status information；
2）The statistical analysis of big data；3）Fault pre-alarming and history alarm inquiry；4）According to operation and maintenance flow scheme design operation and maintenance work
Make task and work ticket, carry out operation and maintenance in whole region in order in a manner of unified standard.
Distributed AC servo system layer realizes source-net-lotus control collaboration optimization of portable micro-grid system, and concrete function includes：
1）Randomness electricity optimization is dispatched；2）Randomness power supply is smoothly contributed control；3）Randomness power supply active power scheduling controlling；4）
Voltage ＆ reactive power-control；5）Orderly planned supply and use of electric power control.
Mechanical floor includes meeting sending on real time execution facility information, realizes control and O＆M.
Three mechanical floor, distributed controll layer and concentration decision-making level levels of corresponding control system of the present invention, communication system
It is divided into three communication acquisition terminal, communication sink accumulation, communication main station levels.Its acquisition terminal that communicates corresponds to mechanical floor, communication sink
Accumulation corresponds to distributed controll layer then, and communication main station corresponds to centralized decision-making layer then.Communication acquisition terminal, communication aggregation point are integrated in
In prefabricated cabin, in somewhere secondary device room that communication main station is arranged on according to actual demand outside prefabricated cabin or monitoring room, may not be used yet
It sets.It is connected between communication acquisition terminal and communication sink accumulation by cable, cable is arranged in prefabricated cabin；Communication sink accumulation with
It is communicated between communication main station by wired or wireless mode.
It also can be by external communication output type distributed resource 125 ~ 130, external dc output type distributed resource 120 ~ 124
Integration of equipments is waited to become the part in portable micro-grid system to the prefabricated cabin of portable micro-grid system.
When the stored energy capacitance of internal direct current energy-storage system 115 is inadequate, also can internal communication be set on ac bus 105
Energy-storage system.
It, can be by the system nacelle 301 of the present invention, transformer 103 and its auxiliary when the capacity of portable micro-grid system is smaller
Equipment is helped to be loaded on a platform trailer；It, also can be by the system one of the present invention when the capacity of portable micro-grid system is larger
A nacelle 301 is divided for two or more nacelles 301, and is carried respectively by two or more car bodies.
Heretofore described controllable burden is divided into interruptible load, two class of deferrable load.Controllable burden can predominantly interrupt
Load, such as air-conditioning, water heater（Installation measure and control device need to be transformed）, usually pass through economic contract（Agreement）It realizes, by electricity
Power company signs with user, and in system peak and under the state of emergency, user provides to interrupt as agreed and reduction plans, that is, matches somebody with somebody
Demand response load in power grid；Deferrable load refers to be unable to complete response dispatching of power netwoks, but can follow to a certain extent point
The guiding mechanisms such as period step price, so as to adjust the load of its power demand, such as charging pile, harbour bank electricity.
Uncontrollable load refers to the electric load namely traditional load, general load in addition to controllable burden, this kind of negative
Lotus power demand is relatively fixed, is the chief component of current distribution network load.Such as refrigerator, refrigerator-freezer, illumination household load
Or the industrial productions load such as motor, electrical heating.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and deformation can also be made, these are improved and deformation
Also it should be regarded as protection scope of the present invention.
