Any strategy, considered reasonable for the control of transient modes which occur as the result of a major disturbance in a large electric power system, will require fast and reasonably accurate measurements of at least two states per machine, namely, rotor speed deviation and torque angle. Since any control strategy will probably require an on-line digital computer for decision, computation, and execution, minimal computation time for the determination of state is imperative. Such a computer based technique along with the pertinent hardware for implementation is presented in this paper.
