  • Publication number: 20240146067
    Abstract: A rapid shutdown system and a method for controlling the rapid shutdown system are provided. A disturbance is applied to a direct-current side of an inverter in the rapid shutdown system only when the inverter does not meet a starting condition, i.e., before the inverter starts. Once meeting the starting condition, the inverter normally operates. A shutdown device in the rapid shutdown system determines its state by determining whether the electrical signal at its output end meets the preset condition, and switches itself on or off in response to its determination.

  • Publication number: 20240136817
    Abstract: A rapid shutdown system and a method for controlling the rapid shutdown system are provided. For each of shutdown devices in the rapid shutdown system, an electrical signal disturbance is applied to a direct current bus connected to the shutdown device at least once within each pre-shutdown period of the shutdown device, by an inverter in the rapid shutdown system operating in a mode of limited power output. Then, the shutdown device samples its input parameter and/or output parameter and determines, based on the sampled input parameter and/or the sampled output parameter, whether the electrical signal disturbance applied to the direct current bus meets a preset condition. The shutdown device switches itself on or remains in an ON state in response to a determination result that the electrical-signal disturbance already meets the preset condition.
