The present invention relates to a peak power control system using an emergency generator. The peak power control system is formed of a common power switch (120), an emergency generator (G), a generator switch (130), an inserting power detection unit (141), and an MCU (110). A "peak power control standard time" which is set with a time smaller than "peak power time of a power supplier" which is set by a power supplier sets to determine peak power, and a "peak power control standard value" are stored in an internal memory of the MCU (110). If it is determined that total power amounts inserted into a customer from the inserting power detection unit (141) is received, and an inserting power value maintains above the peak power control standard value during the peak power control standard time" which by comparing the peak power control standard value with a power value inserted into the customer, a switching-on control signal is outputted through the generator switch (130) and a switching-off control signal is outputted through the common power switch (120). Therefore, it is prevented that inserting power greater than the "peak power control standard value" is supplied over the "peak power control standard time". It is prevented that a peak power value which is determined by the power supplier gets higher than the "peak power control standard value" which is determined by the user. As a result, an electric fee is saved. [Reference numerals] (141) Inserting power detection unit; (142) Generator power detection unit; (G) Emergency generator; (L2,AA,BB,L1,CC,DD) Load |
