Abstract

The invention relates to an uninterrupted power supply system, which belongs to the field of uninterrupted power supply. The system includes an AC power supply, an AC switching power supply module, and a monitoring system / secondary equipment. The AC power supply is connected to the monitoring system / secondary equipment through the AC switching module. The uninterruptible power supply system also includes a high-voltage DC module that provides direct current and a DC interlocking module that regulates DC and AC switching power supplies. The high-voltage DC module is connected to the monitoring system / secondary equipment through the DC interlocking module. module. In the present invention, high-level electricity is used to directly obtain electricity from the high-voltage battery pack of the energy storage device to ensure the stable operation of the secondary equipment and the monitoring system, and can be converted into AC to supply the control coil of the AC main circuit, which solves the problem of the prior art In the case of medium and long-term power outages, the UPS cannot work, resulting in the failure of the energy storage system to operate normally.

Description

technical field [0001] The invention belongs to the field of uninterrupted power supply, and in particular relates to an uninterrupted power supply system for a monitoring system, in particular to an uninterrupted power supply system for a monitoring system of a high-power energy storage device. Background technique [0002] As human society enters the 21st century, based on the gradual depletion of limited petrochemical energy and the increasingly serious environmental pollution, people call for the establishment of renewable clean energy to replace the existing energy structure, so solar photovoltaic power generation technology and wind power generation technology are used as The Lord's new energy technology was established and developed rapidly. The power generation of new energy such as wind energy and solar energy is volatile and random, so people put forward the concept of microgrid on the basis of distributed power generation. Among them, the energy storage system is...
