Abstract
A shutdown control system and a shutdown control method are provided. A main circuit is a series circuit formed by connecting output ends of multiple shutdown circuits in series or a series-parallel circuit formed by connecting output ends of multiple such series circuits in parallel. Each of the multiple shutdown circuits is connected to at least one of direct current power supplies in a distributed power generation system. A control circuit includes a SCU, one or more ACUs, and multiple PCUs corresponding to the multiple shutdown circuits. The SCU and the ACU are configured to transmit respective mode control instructions when respective condition is satisfied. Each of the multiple PCUs is configured to obtain multiple criteria based on the mode control instructions, determine a target operation mode of a corresponding shutdown circuit, and control the shutdown circuit to operate in the target operation mode.
