The composite load model with an induction motor in parallel a static has been studied and applied analysis of dynamics power systems for long time. However, the parameters from field tests are still very limited. Based on theoretical results identifiability estimation methodology that have achieved previous work, project modelling based measurements is described. Eight sets equipment were installed HeNan Electric Power Grid (HNEPG) Corporation, recorded dynamic index proposed to evaluate characteristics data measured. models derived stability HNEPG. critical clearing time transfer capability analyses illustrate enhancement grid using show benefits application such system analysis.
