Electrochemical energy storage dynamic reconfigurable digital energy exchange system and protection method

Abstract

The application provides an electrochemical energy storage dynamic reconfigurable digital energy exchange system and a protection method, the system comprises an energy flow link, an information flow link and an independently arranged safety flow protection system; the safety flow protection system is used for executing high-voltage isolation protection actions independently of the energy flow link and the information flow link in the case of abnormal power failure, so as to prevent system devices from being damaged due to bearing system high voltage; the safety flow protection system comprises an emergency detection circuit and a high-voltage isolation protection unit; the emergency detection circuit is used for monitoring the voltage of an auxiliary power supply for supplying power to a control system in real time, and outputs a protection trigger signal when detecting that the voltage is lower than a set abnormal threshold; the high-voltage isolation protection unit is used for rapidly cutting off system high voltage after receiving the protection trigger signal. The application constructs a safety flow protection system independently of the energy flow link and the information flow link, and can realize rapid isolation and safety protection under abnormal working conditions.
