In order to better illustrate it is provided in an embodiment of the present invention there is the standby power system of energy storage, below by tool
Body embodiment further illustrates.
Embodiment 1
A kind of internal circuit configuration of UPS is as shown in Figure 4.The stand-by power supply of rechargeable battery cell 11 provided in this embodiment
Part and energy storage section use same battery pack, that is to say, that the stand-by power supply of 100Ah is needed inside the present embodiment UPS, that
The stand-by power supply rated capacity that rechargeable battery cell 11 is formed is 120Ah.
In the circuit, mainly have and bypass the preferential and preferential two kinds of operating modes of rectification.In the case where bypassing mode of priority, from 0：
To 5 when 00：When 00 (electricity price is located at trough), one powering load of circuit, circuit two charges to 120Ah to stand-by power supply 11
(V1), from 5：To 8 when 00：When 00, one powering load of circuit, circuit two carries out floating charge to battery.From 8：To 16 when 00：When 00
(electricity price is located at wave crest), power supply 11 starts to discharge, powering load, from 16：To 18 when 00：When 00,11 electricity of power supply reaches
100Ah (V2), is switched to circuit one and powers.From 18：To 20 when 00：When 00 (electricity price is located at next trough), circuit one is to negative
Power supply is carried, circuit two charges to 120Ah (V1) to power supply 11.From 20：To 24 when 00：When 00, one powering load of circuit, circuit
Two pairs of power supplys 11 carry out floating charge.When 5：00 up to 8：When 00 or 20：00 up to 24：Mains failure, power supply are run between when 00
11 electricity is 120Ah, higher than the requirement of UPS stand-by power supplies；When 8：00 up to 16：When 00 or 18：00 up to 20：When 00
Between run into mains failure, the electricity of power supply 11 is between 100Ah to 120Ah, also above the requirement of UPS stand-by power supplies；When
16：00 up to 18：Mains failure is run between when 00, the electricity of power supply 11 is 100Ah, also conforms exactly to UPS stand-by power supplies
It is required that.So running into mains failure in whole process, power supply 11 meets the requirement of UPS stand-by power supplies at any time.If UPS
During failure, then it is switched to circuit three and powers.
Under rectification mode of priority, from 0：To 5 when 00：When 00 (electricity price is located at trough), two powering load of circuit, at the same time
Also 120Ah (V1) is charged to power supply 11, from 5：To 8 when 00：When 00, two powering load of circuit, while power supply 11 is carried out
Floating charge.From 8：To 16 when 00：When 00 (electricity price is located at wave crest), power supply 11 discharges, powering load, from 16：To 18 when 00：00
When, 11 electricity of power supply reaches 100Ah (V2), is switched to circuit two and powers.From 18：To 20 when 00：(electricity price is positioned at next when 00
Trough), circuit two continues powering load, while charges to 120Ah (V1) to power supply 11.From 20：To 24 when 00：When 00, line
Two powering load of road, while floating charge is carried out 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, power supply 11 meets that UPS is standby at any time
With the requirement of power supply.If during two failure of circuit, being switched to circuit one and powering, when UPS failures, it is switched to circuit three and powers.
Therefore, when electricity price is located at trough, power supply 11 can charge, and can discharge when electricity price is located at wave crest, so as to
Peak valley price difference is obtained to reduce equipment investment cost, improve the utilization rate of equipment.In this way, 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.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
Any modification, equivalent substitution or improvement made within refreshing and principle etc., should all be included in the protection scope of the present invention.
