The invention discloses a low-frequency load reduction control system, which consists of a storage unit, a DSP bus, a computing function module CPU1, a management function module CPU2, a data acquisition module, a watchdog, an optical isolation module, a switch input/output module, a dual-port RAM module, an RS232 interface unit, a keyboard, an indicator light and a liquid crystal screen. A working method thereof comprises the following steps: 1, adopting a low-frequency load reduction mode of 'an emergent wheel and a basic wheel and a backup wheel' to timely act; 2, judging again that whether power vacancy exists in the system; and 3, determining a load reduction range. The low-frequency load reduction control system has the advantages of high data processing capacity, high precision and accuracy, simple operation and self-checking and self-recovery functions.
