This paper presents a practical yet accurate equivalencing method of power system for an online transient stability assessment. The proposed vector composition method effectively aggregates the multiple generators and transmission lines of the power system, and develops a grid-adaptive equivalent for which well-established analysis technique can be applied to assess the power system stability. It thus allows for activating preventive or corrective measures on time to stabilize the system in emergency. The parameters of the equivalent can be refined using the synchronized measurement data, and the transient stability margin can be updated. The efficacy and accuracy are validated for a multi-machine infinite bus system, and the utility planning model of Korea electric power system where an equal area criterion and the generator tripping are employed for assessing the stability and stabilizing action as specified in the special protection schemes for the Korea electric power system.

This paper presents an on-line stabilization control method developed with the aim of maintaining transient stability in a local power system which includes large-capacity generation plants. The characteristics of this method are that the powerlangle curve is estimated from the on line active and reactive power measured at the generator terminal, and the optimum generation shedding for stabilization is determined by applying the equal area method to this curve.Simulation tests using detailed models of the power system confirmed that the optimum generation shedding for stabilization could be computed for various fault conditions, both symmetrical or asymmetrical.It was also determined that the on-line data could be sampled for several tens of milliseconds after clearing the fault. Thus, this method provides effective control logic for practical stabilizing systems.1SSN0424-7760/92/0001-0039$7.50/0 Q 1992 Scripta Technica, Inc.
