Abstract
A shutdown control system and a shutdown control method are provided. A shutdown unit is a series circuit of multiple shutdown circuits connected in series or a series-parallel circuit of multiple such series circuits connected in parallel. Each shutdown circuit is connected to at least one direct current power supply. A SCU periodically transmits a first communication signal until receiving a first user command. A TCU controls states of a electrical energy transforming unit to control the operation state of a power generation system. Each PCU determines whether the first communication signal is received during a preset time period and whether the distributed power generation system operates in a power generation state, and controls a corresponding shutdown circuit to operate in a normal operation mode if at least one of the conditions is met; and otherwise operate in a security mode.
