Ampere Magnitude Line Measurements for Power Systems State Estimation

Abstract

This paper describes methods for overcoming the problems associated with utilizing ampere magnitude line measurements in Power System State Estimators. The applicability of ampere magnitude measurements to Power System observability and on-line use in Energy Control Centers is examined. A simple five bus example is presented to point out various properties of ampere solutions and further test results with the IEEE 30 bus test system are discussed.
