AI Technical Summary

Technical Problem

When the existing high-voltage direct-mounted cascade energy storage system fails on the power grid side or the energy storage converter needs to be repaired, the power supply failure occurs, and the power module cannot be bypassed in time, resulting in the system being unreliable.

Method used

A cascade energy storage power module is designed, and a dual-channel redundant energy-earing power supply unit is used to extract power from the battery side and the power module side through the first and second power supplies, and provides dual-channel power supply to the coil of the bypass switch to ensure that the bypass switch is reliable in the event of a power supply failure.

Benefits of technology

It realizes the timely removal of units during power grid failure or maintenance, improves the stability and reliability of the circuit, and avoids system crashes caused by power supply failure.

Abstract

The utility model relates to a cascade energy storage power module and a double-path redundant energy-taking power supply unit, which belong to the technical field of energy storage and power supply and respectively take electricity from a battery side and a power module side by using a first power supply and a second power supply. The first power supply and the second power supply simultaneously supply power to the coil connected with the bypass switch in the control module, so that the bypass switch has double-circuit power supply, the bypass switch can work normally when a power supply fault occurs, a unit can be cut off in time when a power grid fails or needs to be overhauled, and the stability of the circuit is improved.
