The uninterruptible power supply can provide an energy source for the load in the power distribution system when the commercial power is cut off, namely, when the commercial power stops supplying power to the load in the power distribution system, the uninterruptible power supply can provide energy for the load in the power distribution system, and therefore the power failure probability of the power load in the power distribution system can be greatly reduced. The electric energy acquisition and distribution component can distribute and collect the output electric energy of each main circuit and each branch circuit of the commercial power or the uninterrupted power supply according to the power consumption requirement of a user; the electric energy acquisition module can perform data operation on the acquired data of the electric energy acquisition and distribution component so as to convert the acquired data into target conversion data which can be used for controlling each branch load by the display monitoring module; when the electric energy acquisition module sends the target conversion data to the display monitoring module, the display monitoring module can remotely monitor and display the power utilization data on each main road and branch in the power distribution system according to the target conversion data.
Specifically, the display monitoring module can display and monitor the power consumption data in the power distribution system in real time through the local area network. In practical application, the display monitoring module can be set as a color touch screen.

If the uninterruptible power supply cannot provide sufficient energy supply for the electric loads in the power distribution system, the display monitoring module can also remind the customer to preferentially supply power to important loads in the power distribution system so as to reduce the economic loss suffered by the customer.
Therefore, in the power distribution system provided by the embodiment, an uninterruptible power supply, an electric energy acquisition and distribution part, an electric energy acquisition module and a display monitoring module are arranged; the electric energy acquisition and distribution component can distribute and collect the electricity consumption data of each main circuit and each branch circuit of the commercial power or the uninterrupted power supply according to the electricity consumption requirement, and the electric energy acquisition module can perform data operation on the acquired data of the electric energy acquisition and distribution component to obtain target conversion data; meanwhile, the display monitoring module can remotely monitor and display the power utilization data of each main road and each branch according to the target conversion data.

When 8 second voltage sampling channels, 4 second current sampling channels and 4 digital quantity input detection channels on the main circuit board transmit the acquired data to the second control unit, the second control unit performs data operation on the data acquired by the current transformers and the voltage sampling lines on each main circuit and branch circuits in the power distribution system and converts the data into target conversion data which can be processed by the second control unit; after the second control unit converts the data collected by the current transformer and the voltage sampling line into the target conversion data, the second control unit can determine the operation state of each main path and each branch path according to the target conversion data.
Specifically, the second control unit may determine whether a phase loss, a harmonic, an undervoltage, or an overvoltage occurs in the commercial power according to the target conversion data. And if the second control unit determines that the acquisition frequency of the sampled data on each main road and each branch road is too high or too low, the acquisition frequency of the sampled data on each main road and each branch road can be automatically adjusted, so that the data acquisition frequency can better accord with the actual operation condition of the power distribution system.
