This paper proposes a new algorithm for an emergency control system which prevents transient instability by generator tripping. The algorithm is based on the energy function method, and it precisely can determine the amount of generation to be tripped. A prototype of the proposed system has been made, and it has been confirmed that the algorithm has been easily implemented in a micro-computer. Furthermore, test results show that the algorithm works well in an ATL (Artificial Transmission Line) System. This paper describes theoretical aspects of the algorithm, implementation and test results.
