Abstract
A recloser is adaptively controlled so that it will operate in a manner responsive to prevailing conditions such as time of day, day of week, and/or load current. A protection setting group is stored in a memory accessible by the recloser controller, and contains a set of instructions for controlling the recloser based on the prevailing conditions. The prevailing conditions are continuously monitored, and the control of the recloser is based on the prevailing conditions and the protection setting group.
Claims20
A method for controlling a recloser for an electrical power line, comprising:
- determining a protection setting group, the protection setting group having at least one associated feature;
- determining a present condition of the at least one associated feature;
- determining a behavior function for the recloser based on the protection setting group and the present condition;
- and
- implementing the behavior function for the recloser, thereby controlling the recloser responsive to the behavior function.
A recloser control system for an electrical power line, comprising:
- a recloser;
- a memory comprising a protection setting group having at least one behavior function with an associated feature;
- and
- a recloser controller coupled to the recloser and the memory for controlling the recloser responsive to one of the at least one behavior functions in the protection setting group.
A computer-readable medium having computer-executable instructions for performing steps comprising:
- determining a protection setting group for a recloser operating on an electrical power line, the protection setting group having at least one associated feature;
- determining a present condition of the at least one associated feature;
- determining a behavior function for the recloser based on the protection setting group and the present condition;
- and
- implementing the behavior function for the recloser, thereby controlling the recloser responsive to the behavior function.
