Integrated protection and control method of single-phase load

The invention discloses an integrated protection and control method of a single-phase load. Power utilization data of user equipment is collected, and whether abnormity occurs in the user equipment is determined according to the power utilization data of the user equipment; and if abnormity occurs, a power utilization fault which occurs in the user equipment is determined according to the power utilization data, and a corresponding power utilization protection strategy is made, so that a power supply protector implements corresponding power utilization protection according to the power utilization protection strategy. According to the method, safe and reliable power utilization can be realized in different abnormal and fault states of the power distribution network; comprehensive integrated power utilization protection includes protection against short circuit, overload, and voltage instability and imbalance caused by break of zero line, open phase and single-phase high resistance to the ground; the power utilization equipment is prevented from burnout caused by abnormal voltage and current change; the continuity, reliability and quality of power supply are ensured by the protection and control measures; loss of impact load, harmonic wave load and imbalance load is avoided; and the ideas of safety and energy saving are fully embodied.
