ESTIMATION OF PARAMETERS FOR A THERMAL MODEL OF A HIGH VOLTAGE LINE.

摘要

A method for estimating model parameters (A, B, ...; C1, ...) of a thermal model of a high voltage line (10), comprising - measuring values of an electrical magnitude (I , P) of the high voltage line and of meteorological quantities (Ta, S, W) that represent environmental conditions of the high voltage line, and - calculate values of the model parameters from these measured values, characterized in that the method comprises - repeatedly measuring, during the operation of the high voltage line, temporary values (I i, Ta i, S i, W i) of the electrical and meteorological quantities, - concurrently measuring a temporary value (T1 i) of a temperature (T1) of the high voltage line, and - calculate, repeatedly during the operation of the high voltage line, the values (A i, B i; ...; C1 i, .. .) of the model parameters from these measured values.
