Bench control system；
The PV arrays by the photovoltaic DC-to-AC converter by the DC conversion of generation for alternating current sends to the bus,
Power network is incorporated to the bus simultaneously, and circuit controling switch is provided between the power network and the bus, and the STS intelligently switches cabinet
It is located between the twin-stage energy accumulation current converter and the grid entry point of the bus, energy storage electricity is connected with the twin-stage energy accumulation current converter
Pond, also being accessed in the bus has an AC load, the PC background control systems respectively with the photovoltaic DC-to-AC converter, twin-stage energy storage
Current transformer and circuit controling switch are communicated to connect.
Wherein, twin-stage energy accumulation current converter (PCS) is made up of DC/AC two way convertors, control unit etc..PCS controllers lead to
Cross communication and receive Background control instruction, symbol and size the control current transformer according to power instruction are charged or put to battery
Electricity, realizes the regulation to network re-active power and reactive power.PCS controllers are communicated by CAN interface with BMS, obtain battery
Group status information, is capable of achieving the protectiveness discharge and recharge to battery, it is ensured that battery operation safety.
As shown in Fig. 2 in the present invention, the twin-stage energy accumulation current converter for using includes high-tension battery group energy accumulation current converter and low
Piezoelectric battery group energy accumulation current converter, wherein, A-battery group energy accumulation current converter and the one-to-one connection of A-battery.For high pressure

Connected with the main line after connection, intelligently switching cabinet is in parallel with the STS for the service switch.
The Main Function of STS be input power all the way break down or need to overhaul, test when realize from power supply all the way
Veritably changed incessantly between another road power supply, forbid access two-way to produce the input power of backflow.STS can lead to
It is main power source to cross control panel and set wherein any input power all the way, and another road input power is stand-by power supply.Only in master
In the case of power failure or hand-reset, STS just can be switched to stand-by power supply in 8ms from main power source automatically.The two-way of STS
Static switch is strict interlocking, and manual bypass switch is also equipped with STS, when STS needs maintenance, can manually by input electricity
Source is switched to by-pass switch.Can ensure that output is uninterrupted when carrying out manual switch.
The all of conversion of STS is all quick break-before-make, and dash current will not be produced between main power supply, all of
Conversion is completed all within the time less than 8ms.
Under normal operating conditions, it is in normal voltage range in main power source, load is connected to main power source always.In master
During power failure, load automatic switch to stand-by power supply, after main power source recovers normal, load automatically switches to main electricity again
Source.
When the load current of STS sensings exceedes overcurrent value set in advance, dash current or overload are indicated, at this moment
Even if main power voltage exceeds normal voltage range, STS does not also change.When load current returns to normal value, mistake
Stream suppression mode automatically resets, and STS returns to normal mode of operation.
It is in normal voltage range in backup power source voltage, and phase difference between stand-by power supply and main power source is in and permits
Perhaps in the range of.STS can be switched over manually between two-way power supply.In order to the supply of proof load power supply is not interrupted,
When loading the power interruptions of connection, STS will be transformed into another road power supply in 8ms automatically.The urgent preferential any conversion of conversion or
Person suppresses.
PV arrays by the photovoltaic DC-to-AC converter by the DC conversion of generation be with the same amplitude of bus voltage, with frequency, same
The alternating current of phase sends bus to, to bus-powered.
In the system is located at electrical changing station, the load in bus includes charger and other AC loads.When in electricity consumption
During peak period, such as commuter time or festivals or holidays, power consumption is more to be changed, it is necessary to carry out electrokinetic cell relatively largely and fill
Electricity, now, it is possible to which the generated energy of photovoltaic generation can not completely supply the power consumption of bus, it is necessary to power network is aided in bus simultaneously
Power supply, to meet the demand of bus.Now, system is set in STS intelligently switching cabinet, when the current magnitude in bus is less than pre-
If specific threshold or during threshold range, intelligently switching cabinet directly carries out circuit conversion to STS, or starts energy-storage system
Energy-storage battery to bus-powered, while can also power network assist photovoltaic generation together to bus-powered simultaneously, three-phase circuit is together
To bus-powered, to reach the purpose of peak load shifting.
Or when in rainy weather, photovoltaic generation cannot be realized, at this time, it may be necessary to power network is fully relied on to bus-powered, can
With set in advance PC background control systems volitional check photovoltaic DC-to-AC converter in rainy weather electric current export maximum, individually by
Power network to bus-powered, or, intelligently switching cabinet directly carries out circuit conversion to STS, by starting PCS by depositing in energy-storage battery
Reserve of electricity feeds back to bus.
In order to improve reception utilization rate of the solar panel array for sunshine, while solar cell can be protected
Plate reduces the erosion and destruction of acid rain or other materials to it, can preferably be located at the PV arrays and is made up of low iron glass
Containment vessel in, the bottom of the containment vessel is provided with the support frame according to sunlight angular turn, institute for the PV arrays
The inwall for stating containment vessel is provided with high power light source.The high power light source set on inwall ensure that the sun to a certain extent
Even if energy cell panel is within the illumination weaker short time, it is also possible to by absorbing heat and then the guarantee one that these light sources are distributed
Fixed generated energy, such as ensure the need for electricity of small user.These high power light sources can be lighting device.
The AC load includes being provided to electrokinetic cell the charger of power supply, and the PC background control systems fill with described
Its communications are connected.Other AC loads can also be included simultaneously, the alternating current in the bus also can be used.
The present invention also provides a kind of control method of energy-storage system, comprises the following steps：
