The subject of the identification of the equivalent circuit parameters of large synchronous generators is revisited. The equivalent circuit of Park is used. On-line measurements are used in a Kalman filter to estimate the machine parameters. The formulation is linear and the extended Kalman filter is not needed. The approach is similar to that of Harley (1992), but flux linkages are not used in the...
Synchronized measurements technology plays a vital role in the deployment of the Smart Grid at transmission level by revolutionizing the way power systems are operated and controlled. Utilizing very precise time reference enabled by the GPS system allows for measurement synchronization and ultimately optimizes the management of power network behavior and performance. This paper presents SRP experience...
Accurate knowledge of transmission line impedance parameters helps to improve accuracy in relay settings, post-event fault location and transmission power flow modeling. Four methods are presented in this paper to identify transmission line impedance parameters from synchronized measurements for short transmission lines. Estimates of parameters for short transmission lines is more challenging than...
Routinely, measurement errors are identified and removed from the measurement data set and the state estimator re-runs to obtain a better estimate of the state. For some persistent measurement errors, this means permanent loss of the measurements. A better solution is to identify and correct these errors, if possible, so that these measurements can still be used. This paper proposes methods for identifying...
