Abstract:
1. A power distribution system adaptive protection algorithm that continuously monitors itself for changes so that as the state of the power distribution system changes, a new set of protective device trip characteristics can be calculated and implemented, the power distribution system including power sources and loads and having a plurality of circuit breakers, and further including at least one bus and a circuit breaker for said bus, the adaptive protection algorithm comprising: (a) a distribution system power flow tracer; (b) a circuit breaker rank assigner that assigns rank to each of the circuit breakers based upon closeness of the power sources and end loads; (c) a response time assigner that determines response time for each of the circuit breakers in the distribution system based upon the assigned rank; (d) a memory that stores information identifying each circuit breaker in the distribution system; and (e) at least one information table to store information that is collected, said information further comprising one or more of bus location and size, circuit breaker location, circuit breaker identification number, service from/to identifier, and circuit breaker type classification, such that circuit breaker trip set points are continuously updated.
