Discharge method, discharge device and terminal of ups backfilling energy

Abstract

The invention is applicable to the technical field of UPS, and provides a discharge method, a discharge device and a terminal for UPS backfilling energy. Wherein, the discharge method includes: judging whether the UPS has energy backfeeding; if the UPS has energy backfeeding, then controlling the energy discharge circuit of the UPS to conduct with the busbar of the UPS, and controlling the designated components of the UPS to execute the preset energy Consumption action; when the conduction time between the energy discharge circuit and the busbar reaches the preset duration, or when it is detected that the reverse energy of the UPS is less than the preset value, the energy discharge circuit is controlled to be disconnected from the busbar. On the one hand, the present invention utilizes the energy discharge circuit to consume the energy discharged back to the bus, and on the other hand, uses the designated components of the UPS to execute the preset energy consumption action, realizing the rapid discharge of the back fed energy, which can It prevents the bus from being fed back to the high-voltage protection state to cause power interruption, and can disconnect the energy discharge circuit in time after the back-feeding energy is reduced.

Description

technical field [0001] The invention belongs to the technical field of UPS, and in particular relates to a discharge method, a discharge device, a terminal and a computer-readable storage medium for UPS backfilling energy. Background technique [0002] Uninterruptible Power Supply (UPS for short) is a system device that connects an energy storage unit (such as a storage battery) with a host computer and converts DC power into commercial power through the inverter of the host computer. It is mainly used to power a single computer, computer The network system or other electrical equipment such as solenoid valves, pressure transmitters and other loads provide stable and uninterrupted power supply. [0003] In some application scenarios, the load may feed energy back to the UPS. For example, if the UPS has a motor-type load, when the motor brakes or accelerates, the motor will feed energy back to the UPS, which may cause the bus of the UPS to be fed back to the UPS. High voltag...

Problems solved by technology

[0004] In view of this, the present invention provides a discharge method, discharge device, terminal and computer-readable storage medium for UPS backfilling energy, aiming to solve the problem of backfilling energy from loads to UPS in the prior art, resulting in UPS failure. The busbar is fed back to the high voltage protection state, and then the power supply is interrupted.
