Aging of uniting is impartial, improves the reliability of system, but there is power conversion at this time, and system effectiveness is caused to reduce.
The roads B input power circuit is as using exchange UPS, the wake-up of the UPS module needs again due to battery cannot directly back up
Regular hour, therefore UPS can be only in Hot Spare, because Hot Spare is there are no-load loss, therefore energy-saving effect unobvious.
It can thus be seen that it is to use double circuit power supply that the present invention is identical with the method for supplying power to that the prior art is supplied to,
The reliability of guarantee system；Except that acquiring current first power module group and the second electricity in real time by detecting control module
The output voltage values of source module group, and control two power module groups suspend mode backup and with carry quantity, to reduce entire power supply
The loss of system.
Below by taking the roads A input power is electric main as an example, as shown in fig. 7, specific for electric installation composition and connection relation
As described in Figure 3, it does not repeat, the present invention is described in detail for the energy-saving effect of electric installation herein only.
If all ICT equipment total power consumption 320kW of some typical IDC computer room, when using UPS traditional two 400kW
System constitutes double circuit power supply device, it is assumed that conversion efficiencys of the UPS in load factor 80% is 93%, 40% load factor time-varying
It is 91% to change efficiency.To ensure that power supply safety needs certain surplus, the load factor in double circuit power supply system per circuit is maximum
No more than 40%, at this point, the conversion loss of UPS is 320kW/ (91%) -320kW=31.6kW.
The present invention, the circuits A is such as used to provide alternating current by the alternating current stablized, the circuits B use 20 * 20kW rectifier modules
The 336V DC power systems of composition, when normal work, it is only necessary to which a rectifier module is battery float and is second source
The unloaded of module group provides power supply.Assuming that conversion efficiency of the rectifier module in 80% load factor is 93%, 40% load factor
When efficiency be 91%, then only there are one the loss of rectifier module be about 16kW/ (93%) -16kW=1.2kW when working normally.
When second power supply module group is arranged to Hot Spare work, power 31.6kW-1.2kW=30.4kW is saved；Then power saving in 1 year：
(30.4kW*365*24h=266304kWh about 26.6 ten thousand kWh).For the IDC computer rooms of 4MW power consumptions, then power saving in 1 year：26.6*
(4000/320)=332.5 ten thousand kWh.The loss of first power module group and second power supply module group is in the present invention and previous scheme
In exist, therefore do not consider to be included in compare, if consider the reduction of the air-conditioner power consumption resulted in the need for by the reduction of the loss of power, or

Energy photovoltaic output is without energy storage device.Energy is supplied by the roads A solar energy and the first power module group needed for being loaded when solar energy is normal
Electricity loads required energy part and is provided by the circuits B when solar energy dies down, night or rainy days then pass through direct current by alternating current B completely
Power supply and the power supply of second power supply module group.Because considering the unstability of solar energy, the rectifier of suspend mode in the DC power supply of the circuits B
Module number is opposite to be reduced, to avoid frequent suspend mode and wake-up.This device had both reduced the equipment of solar energy and the investment of occupation of land
Solar energy can be made full use of again.
For a 320kW power consumption computer room, photovoltaic module provides about 15% electric power, other to be provided by alternating current, the sun
Energy photovoltaic generation can save alternating current 15%*320kW=48kW.
