Abstract:
This paper investigates the estimation of synchronous generator states
and parameters related to angular stability using PMU data. The method
proposed in this paper uses finite difference technique and least
squares method to evaluate differential equations governing the
synchronous machine using a time window of PMU measurements. Sensitivity
studies have been carried out to evaluate the impact of system
strength, transmission line length, machine controls (exciter and
governor) and local load on estimation accuracy. The simulation studies
demonstrate the feasibility of the proposed method in dynamic states and
parameters estimation.
