A sub-region time-sharing energy-saving power supply system and method, the system comprising: at least one power source (PS); plural users (U1, U2, U3); and plural energy-saving controllers (1, 1a, 1b), wherein each energy-saving controller (1, 1a, 1b) has a processing unit (12), a power supply unit (13), a timing unit (14), a first circuit switch (K1) and a power-off period control unit (11, 11a, 11b). The power-off period control unit (11, 11a, 11b) is connected to the processing unit (12) and is preset with and stores a plurality of rotating power supply intervals. Each rotating power supply interval is preconfigured with a scheduled power-off time and a scheduled power-restore time. The preset and stored scheduled power-off time and scheduled power-restore time are set on the basis of a regime in which power-off times are mutually exclusive. In the rotating power supply intervals, the energy-saving controllers (1, 1a, 1b) of each user (U1, U2, U3) are set with scheduled power-off times and scheduled preset power-restore times in a mutually staggered manner. The invention provides a simple time-sharing control enabling power-saving of an entire system, and does not require an increase in the power generation capacity of any power system. |
