Abstract

Disclosed is a method for determining a position of a forced power oscillation disturbance source in a regional interconnected power grid relating to dispatching automation of an electric power system and safety operation of a power grid. According to the method when forced power oscillation occurs in a regional power grid an algebraic sum of energy flow directional factors in the regions of the regional interconnected power grid is calculated so as to determine the position of the disturbance source. Compared with the conventional disturbance source positioning method based on an energy function the disturbance source positioning method based on calculation of the energy flow directional factors provided by the present invention can reduce the impact of a periodic disturbance component and an initial constant on the determination of an aperiodic component of branch potential energy thus achieving higher accuracy; moreover the integration links are reduced and the calculation process is simplified thus better meeting the requirements for real time power grid calculation.
