Technical field
The present invention relates to data center's power-supply service technical field, and in particular in a kind of wind energy data for saving low stain
Heart electric power system.
Background technology
In design server data center, in order to prevent data center civil power power-off after server occur the machine of delaying or
Person's power-off causes loss of data, generally, UPS can be all designed during design and battery ensures that data center is fallen in civil power
After electricity can normal work for a period of time.
But the data center equipped with ups system needs to change by 3 AC/DC, so results in the utilization rate of electric energy
Compare low, it is impossible to realize good energy-saving effect and stability.
If data center needs continual work for a long time, UPS and battery cannot ensure long-play.
The data center having to solve this problem uses electrical power generators, can ensure the stable fortune of data center
OK, but this has certain flaw for green data center, and certain pollution can be produced to environment, does not meet energy-conservation
Need.
The content of the invention
The technical problem to be solved in the present invention is：In view of the above-mentioned problems, the present invention provides a kind of wind energy for saving low stain
Data center's electric power system.
The technical solution adopted in the present invention is：
A kind of wind energy data center electric power system for saving low stain, the electric power system include：Wind generator system, high straightening
Flow module HVDC systems, battery, wherein, the power supply order of the electric power system is：Wind generator system power supply, HVDC systems
Power supply, storage battery power supply.
HVDC, high-voltage direct current HVDCs (electricity), it is the skill of a very attractive
Art, because in electricity transmission process, the electric energy loss of HVDC technologies is less than the loss of conventional AC technology of transmission of electricity, while HVDC needs
Transmission cable it is less, occupation of land can be reduced.
When not enough power supply caused by wind power system is to meet data center's electricity consumption, remaining electricity has power network supply.Such as
After the power-off of fruit civil power, the electricity of the needs of data center has wind power system offer, is powered simultaneously with battery when insufficient, to meet
The normal work of data center.
The wind generator system provides the direct current that voltage is 380V.
The HVDC systems provide the direct current that voltage is 336V.
The battery provides the direct current that voltage is 240V.
These three power supplys, the more preferential power supply used, the voltage of setting are higher.
The wind generator system produces the alternating current of change, and the alternating current of change is direct current by charger rectification,
Direct current through again and series connection, voltage is brought up into 380V, parallel connection is then being carried out to multichannel 380V DC voltages, it is caused big
Power high voltage direct current is supplied to data center to load, and is finally converted into server by the DC/DC modules in data center
12V operating voltages.
The wind generator system is responsible for charging a battery when accumulator electric-quantity deficiency.
Electricity caused by the wind generator system be more than data center required for electricity when, unnecessary electricity passes through
PWM rectifier is converted into the alternating current of power frequency, is connected in parallel on power network.
Beneficial effects of the present invention are：
The present invention instead of ups system by the way of direct current supply, reduce electric energy AC to DC conversion times, apparatus of load
Rate is high, plus energy-conservation sleep management, greatly improves system whole efficiency.Ups system is eliminated, reduces area occupied, can be with
Increase the quantity of server, improve the density of the server of data center, increase the disposal ability of data.
UPS power supplies, HVDC and electric power operation electricity is widely used in communication at present, data service and Modern Information Service Industry business
Source principle is similar, alternative UPS uninterrupted power sources, also more favourable than UPS more power savings, HVDC 70% of initial cost less than UPS
In safeguard the features such as.
High-voltage direct current small investment, and the unnecessary electricity in wind system power generation station can feed back to power network, can not only
Additional income can also be increased by saving the operation cost of data center electricity, to the interests of supplier clearly.
Brief description of the drawings
Fig. 1 is wind energy data center electric power-feeding structure schematic diagram of the present invention.
In figure 1., 2., 3. represent data center three tunnel electric power system, wherein 1. voltage caused by wind power system is that 380V is straight
Stream, 2. the voltage of HVDC systems is 336V, 3. the voltage of battery is 240V.
Embodiment
According to Figure of description, with reference to embodiment, the present invention is further described：
Embodiment 1：
As shown in figure 1, relatively inefficient UPS is replaced with high-voltage direct module HVDC systems in the data center,
Using the form of DC voltage to data center feed；
The main electric power system of data center uses wind generator system, and the alternating current of change is whole by charger caused by blower fan
Stream, then DC voltage is raised, voltage is brought up into 380V DC voltages by series connection, then to multichannel 380V DC voltages
Carry out in parallel, caused high-power high voltage direct current supply data center load.
Embodiment 2
On the basis of embodiment 1, when accumulator electric-quantity deficiency, wind generator system fills the present embodiment to battery simultaneously
Electricity.
Embodiment 3
On the basis of embodiment 1, if electricity caused by the present embodiment wind generator system is more than required for data center
Electricity, unnecessary electricity can be converted into the alternating current of power frequency according to the energy in bidirectional flow principle of PWM rectifier, be connected in parallel on electricity
On the net.
Embodiment 4
On the basis of embodiment 1, the present embodiment works as not enough power supply caused by wind generator system to meet data center's electricity consumption
When, remaining electricity is supplied by utility grid by HVDC systems.
If after civil power power-off, the electricity of the needs of data center is provided by wind generator system, when insufficient and battery
Power simultaneously, to meet the normal work of data center.
Therefore, data center according to wind generator system electric power, civil power electric power, battery discharging order, be server
Power supply.Override utilizes the direct current 380V electric power from wind generator system power station；
It is that wind generator system does not generate electricity or during generation deficiency to take second place, and direct current power is converted to from mains-supplied and by exchange；
When wind power system does not generate electricity or during generation deficiency, when civil power electric power also has a power failure, the direct current from battery is just utilized
Power.
This design eliminates ups system by the way of direct current supply, reduces electric energy AC to DC conversion times, carries
The high utilization ratio of electric energy.The Nature wind power generation is utilized simultaneously, reduces the dosage of civil power, saves the energy.Another aspect energy
Data center can run for a long time after enough meeting civil power power-off, ensure that client is capable of the processing data of normal table, will not
Cause heavy losses.
