The invention discloses an intelligent algorithm for circuit breaking and power limiting. The intelligent algorithm comprises the following steps that a target cut-off load value is set; Filtering thedevice according to the filtering options; Judging whether the power of the equipment meets a 'power selection range' or not; Judging whether the latest control time of the equipment meets the latestcontrol time range or not; Carrying out regional filtering; If the parameter myk _ ctrl _ power _ supply _ area needs to be 1, power supply partition filtering is carried out; If the parameter myk _filter _ set _ st needs to be 1, filtering the plant station; And selecting according to a sequence selection strategy. According to the invention, real-time load data is adopted, which is more accurate, a software intelligent algorithm is used to screen out plant stations in a power maintenance area, and a pull set is automatically generated more quickly and reasonably; A comprehensive sequence is generated according to a given power limiting load, only one round of operation is needed, and time is saved.
