Abstract
This article introduces a model for diagnosing rotor angular changes in generators when integrating synchronous generators into the grid. The model addresses issues like leakage currents, reverse moments, and stator bushing short circuits caused by rotor angle changes during parallel addition of large-capacity synchronous generators. Its unique approach simplifies precise synchronization during parallel connection and enables continuous graphical monitoring of rotor angle changes through computer programs. Experimental results from 110 MW synchronous generators at "Navoi Thermal Power Plant" JSC validate the model's effectiveness. It is designed to resolve rotor angle change challenges when integrating synchronous generators of varying capacities into existing power plants, ensuring uninterrupted electricity supply and optimizing technical and economic performance. The model aims to enhance operational efficiency and reduce costs for electricity consumers.
