Embodiment 1

[0117] Embodiments of the present invention provide a power control system, such as figure 1 As shown, the power control system includes a control device 01, a DC power supply device 02 connected to the control device 01, an AC power supply device 03, and a battery power supply device 04, wherein the battery power supply device 04 and the DC power supply device 02 or the AC power supply equipment 03 is connected.

[0118] Specifically, in the embodiment of the present invention, the control device 01 obtains the output power of the DC power supply device 02, the output power of the AC power supply device 03, the output power of the battery power supply device 04, and the working power of the electric device. Here, the control The device 01 can obtain the working power of the electric device by detecting the rated current and voltage of the electric device. Of course, the terminal device connected outside the control device 01 can also input the working power of the electric de...

Embodiment 2

[0150] Embodiments of the present invention provide a power control method, such as Figure 5 shown, including:

[0151] 101. The control device obtains the output power of the DC power supply device, the output power of the AC power supply device, the output power of the battery power supply device, and the working power of the electric device.

[0152] 102. The control device selects a power supply device from the DC power supply device, the AC power supply device, and the battery power supply device as the first power supply device to supply power to the electric device according to a preset strategy.

[0153] 103. If the output power of the first power supply device is less than the working power of the electric device, the control device selects the second power supply device, and the second power supply device and the first power supply device supply power to the electric device at the same time, and the second power supply device The sum of the output power of the devi...

Embodiment 3

[0171] An embodiment of the present invention provides a power control method. The DC power supply equipment involved in the embodiment of the present invention may include solar power supply equipment, floor heating power supply equipment, natural gas power supply equipment, DC motor power supply equipment, and fuel cell power supply equipment. Take the power supply equipment as an example to elaborate in detail, such as Figure 6 As shown, the method includes:

[0172]201. The control device separately acquires the output power of the solar power supply device, the output power of the AC power supply device, the output power of the battery power supply device, and the working power of the electric device.

[0173] 202. The control device determines the load mode of the electric device.

[0174] 203. If the power control system fails, the control device determines that the battery-powered device is the first power supply device, and sends a power supply instruction to the ba...

Abstract

The embodiment of the invention provides an electric control method, device and system and relates to the technical field of electronics. The electric control method, device and system solve the problem that due to the fact that a power supply input mode in a power supply system is single, and consequently normal power supply of electric equipment cannot be ensured to a certain extent. According to the scheme, the electric control method includes the steps that the output power of a direct-current power supply device, the output power of an alternating-current power supply device , the output power of a battery power supply device and the working power of the electric equipment are obtained; one of the direct-current power supply device, the alternating-current power supply device and the battery power supply device is selected as the first power supply device for supplying power to the electric equipment; if the output power of the first power supply device is smaller than the working power of the electric equipment, the second power supply device is selected, the second power supply device and the first power supply device supply power to the electric equipment at the same time, and the sum of the output power of the second power supply device and the output power of the first power supply device is larger than the working power of the electric equipment.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a power control method, device and system. Background technique [0002] The power supply system can be composed of a power supply system and a power transmission and distribution system, which is responsible for generating electrical energy, supplying and delivering it to electrical equipment, especially in DC (data center, data center), which tends to be digital and intelligent, the power supply system is in Various electrical equipment in the data center play a vital role. [0003] Currently, data centers usually use online UPS (uninterruptible power supply, uninterruptible power supply) system, HVDC (high voltage direct current, high voltage direct current) power distribution system or LVDC (low voltage direct current, low voltage direct current) power distribution system for power supply. These power supply systems convert the power-frequency alternating current...
