System for Controlling an Electrical Power System

A method of limiting power to a plurality of on-line consumers, comprising:

• storing operating characteristics of each of a plurality of generators;
• storing a plurality of maximum torque capabilities for each of a plurality of prime movers, each of the plurality of maximum torque capabilities being based upon at least one operating characteristic of the prime mover;
• storing a plurality of available electrical power responses for each of the plurality of generators, each of the plurality of available electrical power responses being based upon the one of the plurality of maximum torque capabilities of a prime mover driving the generator and the operating characteristics of the generator;
• storing a maximum power demand of each of a plurality of on-line consumers;
• determining a maximum torque capability of each of the plurality of prime movers, the maximum torque capability being based upon data from an operating characteristic sensor associated with the plurality of prime movers;
• determining an available electrical power response of each of the plurality of generators, the available electrical power response being based upon the operating characteristics of the generator and the maximum torque capability of the prime mover driving the generator;
• determining a total available electrical power response, the total available electrical power response being based upon the available electrical power response of the plurality of generators;
• determining a total maximum power demand, the total maximum power demand being based upon the maximum power demand of each of the plurality of on-line consumers;
• comparing the total available electrical power response to the total maximum power demand;
• and
• upon the total maximum power demand exceeding the total available electrical power response, limiting power to the plurality of on-line consumers to no more than the total available electrical power response.

A system for limiting power to a plurality of on-line consumers, comprising:

• an operating characteristic sensor associated with each of a plurality of prime movers for determining an operating characteristic of each prime mover;
• and
• a controller configured to:

• determine a total available electrical power response, the total available electrical power response being based upon the available electrical power response of the plurality of generators;
• determine a total maximum power demand, the total maximum power demand being based upon the maximum power demand of each of the plurality of on-line consumers;
• compare the total available electrical power response to the total maximum power demand;
• and
• upon the total maximum power demand exceeding the total available electrical power response, limit power to the plurality of on-line consumers to no more than the total available electrical power response.
