Technical field
The present invention relates to substation's field of power systems, more particularly, to a kind of change based on energy router technology
Power station station power source system.
Background technique
With scientific and technological progress, requirement of the substation to power-supply device is constantly changing, the development speed of power-supply device itself
It is even more surprising.With the raising of conversion efficiency and switching frequency, volume reducing power conversion module year by year, last decade
Between, the volume of all kinds of high-frequency switching power supply modules averagely reduces 50 % or more, and the power supply that one cabinet of past just has holds
Amount, a present module have been provided with, this reconfigures the condition of providing for power-supply device.Power converter is substantially real
Existing intelligence, provides Intelligent Communications Interface mostly, provides convenience for the Centralized Monitoring of different classes of power module.Energy road
It is even more the intelligent management for being able to achieve distributed generation resource, energy storage device, load etc. by device, under the premise of guaranteeing power quality, spirit
Dynamic electric energy inside ground living management region power grid and in entire power distribution network.
Currently, " station power source system " of substation includes transforming plant DC power-supply system, AC power supply system, exchanges not
Uninterruptible power system.Although they have a large amount of electrical link and energy to convert in substation, in equipment but all certainly
At set of system, the operational management of relatively independent ground.Standing, there is the transfer problems of multiple AC/DC between power-supply device, but also
AC/DC equipment is more in standing, and increases the cost of station interior power equipment and the workload of operation and maintenance.
Summary of the invention
The present invention is to solve equipment room independent operating management in the prior art in station power source system so that equipment room is deposited
In multiple AC/DC conversion, leading to stand that interior power equipment cost is high, operation and maintenance amount is big AC/DC equipment more, providing
A kind of substation's station power source system based on energy router technology.
To realize the above goal of the invention, and the technological means used is:
A kind of substation's station power source system based on energy router technology, including AC power supply system and with AC power source system
Unite the energy router of electrical connection, have on the energy router AC load connectivity port, battery group connectivity port and
DC load connectivity port.
Station power source system provided by the invention, by increasing energy router on AC power supply system come in management station
DC load and battery station uninterruptible power supply load reduce station to manage the station power source system of substation concentratedly
The number of transitions of AC/DC and AC/DC equipment in interior power system.
Preferably, the AC power supply system includes the station local coordinate frame, automatic transfer switching electric appliance, exchange being sequentially connected
Bus and load.
Preferably, the ac bus connects energy router.
Preferably, the energy router is the energy router controlled based on virtual motor.
Preferably, the station power source system includes two AC power supply systems and two energy routers.
Compared with prior art, the beneficial effect of technical solution of the present invention is:
Using a kind of substation's station power source system based on energy router technology, energy router is by the exchange in substation
Power-supply system equipment, DC power system equipment, ac uninterrupted power supply system equipment are integrated into a set of power-supply device, utilize energy
Router is measured to manage the station power source system of substation concentratedly, is solved in substation in the prior art between power of alterating and direct current
Number of transitions it is more, the technological deficiencies such as AC/DC equipment is more, and interior power of standing equipment cost height and operation and maintenance amount are big.
Detailed description of the invention
Fig. 1 is the principle of the present invention figure.
Fig. 2 is the energy router topology diagram based on virtual motor control in the present invention.
Specific embodiment
The attached figures are only used for illustrative purposes and cannot be understood as limitating the patent；
In order to better illustrate this embodiment, the certain components of attached drawing have omission, zoom in or out, and do not represent the ruler of actual product
It is very little；
To those skilled in the art, the omitting of some known structures and their instructions in the attached drawings are understandable.
The following further describes the technical solution of the present invention with reference to the accompanying drawings and examples.
As shown in Figure 1, in an embodiment of the present invention, a kind of substation station power supply system based on energy router technology
System, including 1# station local coordinate frame, the 1#ATS(automatic transfer switching electric appliance being sequentially connected), 1 section of ac bus, load 1；With
And 2# station local coordinate frame, the 2#ATS(automatic transfer switching electric appliance being sequentially connected), 2 sections of ac bus, load 2；It is handed over 1 section
First energy router of stream bus connection, the first energy router being connect with 1 section of ac bus；1#ATS(automatic conversion is opened
Powered-down device) with 2# ATS(automatic transfer switching electric appliance) be connected；
Wherein the first energy router and the second energy router are the energy router controlled based on virtual motor.First energy
All there are AC load connectivity port, battery group connectivity port and DC load on router and the second energy router respectively
Connectivity port.
As shown in Fig. 2, the energy router based on virtual motor control that the embodiment of the present invention uses, its exchange side is adopted
With a group formula inverter circuit, the interface of DC bus and ac bus, 380 V of grid ac voltage, DC bus-bar voltage are realized
110 V or 220V are selected as, it is female effectively to make up traditional Boost type rectifier output direct current using a group formula inverter interface
The deficiency that line voltage is excessively high, voltage stress is big can also seamlessly access 110 V or 220V DC bus.DC side is using half
Bridge circuit module can flexibly work in Boost, Buck and tri- kinds of two-way Buck-Boost according to the difference of power supply and load
Different modes.For photovoltaic and blower application, Boost mode is worked in, the DC voltage pumping-up that renewable energy is exported
To level needed for inverter DC bus-bar voltage.DC load application is worked according to different supply voltage requirements
Buck or Boost mode realizes the flexible power supply to DC load.For stored energy application, two-way Buck-Boost is worked in
The energy flow control between DC bus and energy-storage units is neatly realized in mode.
It will be applied after the present invention based on the energy router that virtual motor controls, since station power source system uses the energy
The group formula inverter interface of router is measured to integrate, the two-way changings of AC/DC can be realized according to the difference of power supply and load, thus
The number of transitions for reducing AC/DC, reduces AC/DC number of devices.
In original substation's station power source system, since ac uninterrupted power supply system is by exchange input, exchange
The power-supply device of exchange uninterrupted power supply is realized in output, intermediate DC link by batteries to store energy, therefore the system is right
Power supply successively carries out an AC/DC transformation and DC/AC transformation；And DC power system needs to carry out an AC/DC transformation.
