The invention provides a power line carrier communication system and method for guaranteed power supply command, the system comprises a receiving module, a modulation module, a processing module and a guaranteed power supply command post, the modulation module is respectively connected with the receiving module and the processing module, and the guaranteed power supply command post is connected with the processing module. The method comprises the steps that: the receiving module carries out coupling receiving and filtering on a power line carrier communication cable signal to obtain a high-frequency carrier signal, then the modulation module modulates the high-frequency carrier signal into at least two paths of orthogonal carrier digital signals with different center frequency points; the processing module encrypts and packages the orthogonal carrier digital signals into data frames, and transmits the power supply guarantee command post is transmitted; and deframing and decapsulation are carried out by the po
