At present, the requirements on power supply quality and reliability of power transmission and distribution in various industries are very strict. The mains supply system is no longer simply mains powered, and with the needs of the industry, the generator set is configured into the mains supply system to ensure that important loads are not affected by a power outage.

When the commercial power is cut off, the communication office room and the power supply system usually provide uninterrupted power supply for the load through the backup battery so as to facilitate the starting and power supply of the generator set, and when the commercial power is recovered, the power supply system charges the backup battery through rectification and supplies power to the load. Therefore, when the mains supply is recovered, the problem of extra occupation of the mains supply power capacity can be caused by concentrated charging of a large number of battery packs, and therefore the resource utilization rate of the mains supply power capacity is low.

Based on this, the embodiment of the application provides a mains supply method, which determines the state of the mains supply according to the first electrical signal, and supplies power to the load through the mains supply access module and charges the battery pack module through the generator pack module under the condition that the state of the mains supply is recovered from power failure. The problem that the electric power capacity of the commercial power additionally occupies due to the fact that a large number of battery packs are charged in a concentrated mode when the commercial power is cut off and recovered can be avoided, and the resource utilization rate of the electric power capacity of the commercial power is improved.

In order to facilitate understanding of the implementation process of the method in the embodiment of the present application, an application scenario in the embodiment of the present application is first described.

As shown in fig. 1, the scenario includes a mains power supply system 11 and a load 12, where the mains power supply system 11 and the load 12 are electrically connected for supplying power to the load 12.

Specifically, whether the rectification/inversion module 1114 rectifies/inverts the electrical signal is determined by the control device 112.

Fig. 4 is a flow chart illustrating a mains power supply method according to an exemplary embodiment. As shown in fig. 4, the method may include the following steps.

Step 41: the control device acquires a first electrical signal.

The first electric signal is an electric signal of a mains supply connected into the mains supply access module.

The control device may include a moving loop monitoring system for detecting an electrical signal of the mains supply connected to the mains supply connection module.

Optionally, the first electrical signal includes at least one of frequency, voltage, and current.

Step 42: the control device determines the state of the commercial power according to the first electric signal.

Specifically, the control device determines that the state of the commercial power is normal when the value of the first electric signal is greater than a first threshold value and lasts for a first time period; determining the state of the commercial power as power supply interruption under the condition that the numerical value of the first electric signal is less than or equal to a first threshold value and lasts for a second time period; and determining the state of the commercial power to be power-off recovery under the condition that the value of the first electric signal rises from the first value to the second value and the second value lasts for a third time period. The first value is smaller than or equal to a first threshold value, and the second value is larger than the first threshold value.

Illustratively, the first electrical signal is a voltage of the utility power, and has a value a, the first threshold value b, the first time period t1, the second time period t2, the third time period t3, the first value c, the second value d, and c ≦ b < d. Determining that the state of the commercial power is normal under the condition that a is more than b lasts for t 1; under the condition that a is not more than b and t2 lasts, determining the state of the commercial power as power supply interruption; in the case where the first electric signal rises from c to d and remains as d for t3, it is determined that the state of the commercial power is the power outage restoration.

Step 43: the control device supplies power to the load through the commercial power access module under the condition that the state of the commercial power is power failure recovery, and charges the battery pack module through the generator set module.

Specifically, the control device inverts the electric signal output by the commercial power access module through the rectification/inversion module and then supplies power to the direct-current load when the load is determined to be the direct-current load. And under the condition that the load is determined to be an alternating current load, the load is directly supplied with power through the commercial power access module.

Before the control device charges the battery pack module through the generator set module, the control device also needs to rectify the electric signal output by the generator set module through the rectification/inversion module and then charge the battery pack module.

Optionally, before the load is powered by the utility power access module and the battery pack module is charged by the generator pack module, the utility power supply method further includes: the control device acquires the second electric signal and determines that the state of the generator set module is normal according to the second electric signal. The second electrical signal is an electrical signal of the generator set module.

Specifically, the control device may include a moving loop monitoring system for detecting an electrical signal (i.e., the second electrical signal) of the genset module. The control device determines that the state of the generator set module is normal under the condition that the value of the second electric signal is larger than the second threshold value and lasts for a fourth time period; and determining that the state of the generator set module is abnormal under the condition that the value of the second electric signal is less than or equal to the second threshold value and lasts for a fifth time period.

Optionally, the second electrical signal includes at least one of frequency, voltage, and current.

Optionally, before the load is powered by the utility power access module and the battery pack module is charged by the generator pack module, the utility power supply method further includes: the control device obtains a third electrical signal, which is an electrical signal of the battery module. And determining that the state of the battery pack module is normal according to the third electric signal.

Specifically, the control device may include a moving loop monitoring system for detecting an electrical signal (i.e., the third electrical signal) of the battery module. The control device determines that the state of the generator set module is normal under the condition that the numerical value of the third electric signal is greater than the third threshold value and lasts for a sixth time period; and determining that the state of the power generation battery pack module is abnormal under the condition that the value of the third electric signal is less than or equal to the third threshold value and lasts for a seventh time period.

Optionally, the third electrical signal includes at least one of frequency, voltage, and current.

Optionally, as shown in fig. 5, the commercial power supply method further includes the following steps.

Step 44: and the control device supplies power to the load through the commercial power access module under the condition that the state of the commercial power is determined to be normal according to the first electric signal.

Optionally, the control device, when determining that the load is a dc load, inverts the first electrical signal through the rectification/inversion module, and then supplies power to the dc load. And under the condition that the load is determined to be an alternating current load, the load is directly supplied with power through the commercial power access module.

Step 45: and the control device supplies power to the load through the battery pack module and the generator pack module under the condition that the state of the commercial power is determined to be power supply interruption according to the first electric signal.

Specifically, because the generator in the battery module is started slowly, in order to ensure that an uninterruptible power supply is provided for the load, the control device immediately starts the battery module to supply power to the load under the condition that the mains supply is interrupted, and simultaneously starts the battery module to supply power to the load instead of the battery module before the electric quantity stored in the battery module is exhausted.

In addition, under the condition that the load is determined to be a direct-current load, the control device controls the rectification/inversion module to rectify the electric signal output by the generator set module and then supply power to the load before the generator set module replaces the battery set module to supply power to the load.

In the above scheme, when the commercial power is normal, the control device supplies power to the load through the commercial power access module, and when the commercial power is interrupted, the power is supplied to the load through the battery pack module and the power generation module. The load can be prevented from being influenced by the power failure of the mains supply, and an uninterrupted power supply is provided for the load, so that the user experience is improved.
