Abstract
This paper describes the implementation of the P-Q capability diagram into the existing monitoring system for the 247 MVA synchronous turbo generator installed in a thermal power plant. The paper also addresses features, characteristics and uniqueness of the existing monitoring system as well as the modeling considerations required for the development of a P-Q diagram. This enables better insight into the operational limits which ensures better utilization of the synchronous generator. The proposed approach and methodology can be used for the implementation of the user real-time P-Q diagram whose limits change dynamically in accordance with operating conditions when the generator operates on the grid.

Summary
Synchronous generators are an essential part of the power systems The expansion of their capabilities represents a great contribution in several different fields. In order to achieve the described properties an adequate measurement system should be installed on the synchronous generator or the existing one should be modified in order to measure and monitor some specific physical quantities. Those measured quantities can be used to refine the analytical model of the synchronous generator to produce a relevant real time P-Q diagram plot. The real time user P-Q diagram is specific for a particular generator and changes with the change of the operating point
