Problems solved by technology
In fact, this method is only applicable to energy storage converters without fault recording function, and additional fault recording function is added, and the errors / faults of direct sampling data and indirect calculation data inside the energy storage converter cannot be read and recorded.
In addition, the fault recording equipment and external voltage / current sensors increase the cost of the system, and the data interaction between the fault recording equipment and the energy storage system will also occupy additional system communication overhead

The invention discloses a fault recording method and device, a storage medium and an energy storage converter, the method is applied to the fault recording device integrated in the energy storage converter, and the method comprises the following steps: obtaining fault recording information, generating fault recording data according to the fault recording information, and writing the fault recording data into a first buffer area, the first buffer area is arranged in a core processor of the energy storage converter; reading the fault recording data in the first buffer area, and writing the fault recording data into an external second buffer area; and reading the fault recording data in the second buffer area, and writing the fault recording data into a nonvolatile storage medium. According to the method, the system cost and the system communication overhead can be effectively reduced.
Description
technical field [0001] The present application relates to the technical field of electrochemical energy storage, and in particular, to a fault recording method and device, a storage medium and an energy storage converter. Background technique [0002] With the rapid development of the current electrochemical energy storage industry, the safety and reliability of energy storage systems have received more and more attention. As the core power equipment of electrochemical energy storage system, energy storage converter, its operation stability and reliability are the key indicators to measure the reliability of electrochemical energy storage system. When the energy storage converter fails, how to realize the accurate and real-time recording of the energy storage converter fault waveform data in a relatively simple way and at a lower cost is the main research direction in this technical field. [0003] The current mainstream fault recording technology methods mainly use externa...
