Abstract

An adaptive relaying control system and method is disclosed for adapting coordination of protective measures provided to an electric-energy distribution system as a function of at least an ambient weather condition. A weather sensor senses the ambient weather condition within a region adjacent to at least a portion of the electric-energy distribution system. A control unit is operatively coupled to the weather sensor to receive a weather signal indicative of the ambient weather condition and determine whether a storm condition exists based at least in part on the weather signal. The control unit establishes a suitable control philosophy for adapting coordination of the protective measures provided to the electric-energy distribution system based at least in part on whether the storm condition exists.

Dependent claims

A method of adapting coordination of protective measures provided to an electric-energy distribution system as a function of at least an ambient weather condition, the method comprising:

operating at least a portion of an electric-energy distribution system in a first mode, wherein:
said first mode comprises a default mode;
and
said electric-energy distribution system supplies electric-energy to a plurality of end users;
analyzing a received signal indicative of an identified ambient weather condition, wherein said identified ambient weather condition comprises weather sensed in real-time for a region adjacent to said at least a portion of said electric-energy distribution system, said analyzing comprising:
determining a storm condition exists if said ambient weather condition meets a storm threshold;
and
determining said storm condition does not exist if said ambient weather condition does not meet said storm threshold;
automatically switching operation of said at least a portion of said electric-energy distribution system to a second mode if said storm condition is determined to exist, wherein said second mode comprises a storm mode;
and
automatically switching operation of said at least a portion of said electric-energy distribution system from said second mode to said first mode if said storm condition is determined to not exist.

8 more elements

An adaptive relaying control system for adapting coordination of protective measures provided to an electric-energy distribution system as a function of at least an ambient weather condition comprising:

a weather sensor configured to sense, in real-time, an ambient weather condition within a region adjacent to at least a portion of said electric-energy distribution system;
and
a control unit, operatively coupled to said weather sensor, and configured to:
receive a weather signal indicative of said ambient weather condition;
determine whether a storm condition exists based at least in part on said weather signal;
establish a control philosophy for autonomously adapting coordination of protective measures for said electric-energy distribution system based at least in part on whether said storm condition exists, wherein said control philosophy comprises one of:
autonomously tripping;
single phase tripping;
adjusting of coordination curves of a microprocessor relay;
adjusting of times for at least one recloser to remain open during the storm condition;
adjusting of relays based upon load from the weather condition;
and
reconfiguring of breakers and reclosers;
and
automatically switch between a default mode and a storm mode based upon whether said storm condition exists.
