During failure, then the power supply of circuit three is switched to.
Under rectification mode of priority, from 0：To 5 when 00：When 00 (electricity price is located at trough), the powering load of circuit two, while
Also 120Ah (V1) is charged to power supply 11, from 5：To 8 when 00：When 00, the powering load of circuit two, while being carried out to power supply 11
Floating charge.From 8：To 16 when 00：When 00 (electricity price is located at crest), power supply 11 discharges, powering load, from 16：To 18 when 00：00
When, the electricity of power supply 11 reaches 100Ah (V2), is switched to the power supply of circuit two.From 18：To 20 when 00：(electricity price is located at next when 00
Trough), circuit two continues powering load, while charging to 120Ah (V1) to power supply 11.From 20：To 24 when 00：When 00, line
The powering load of road two, while carrying out floating charge to power supply 11.When 5：00 up to 8：When 00 or 20：00 up to 24：Between when 00
Mains failure is run into, the electricity of power supply 11 is 120Ah, higher than the requirement of UPS stand-by power supplies；When 8：00 up to 16：When 00 or
Person 18：00 up to 20：Mains failure is run between when 00, the electricity of power supply 11 is standby also above UPS between 100Ah to 120Ah
With the requirement of power supply；When 16：00 up to 18：Mains failure is run between when 00, the electricity of power supply 11 is 100Ah, also just
Meet the requirement of UPS stand-by power supplies.So running into mains failure in whole process, it is standby that power supply 11 meets UPS at any time
With the requirement of power supply.If during two failure of circuit, being switched to the power supply of circuit one, when UPS failures, the power supply of circuit three is switched to.
Therefore, when electricity price is located at trough, power supply 11 can be charged, and can be discharged when electricity price is located at crest, so as to
Peak valley price difference is obtained to reduce equipment investment cost, improve the utilization rate of equipment.So, stand-by power supply can not only be better achieved
Function, and the function of its energy-storage system can be given full play to.
Preferred embodiment of the present utility model is the foregoing is only, is not used to limit the utility model, it is all at this
Any modification, equivalent or improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
