This paper presents an experience in the design and implementation of the condition-monitoring system for the synchronous generators whose primary purpose is to record data for the identification of the capability limits of the P–Q diagram of three generators in hydro power-plant. Paper presents details about the monitoring system, the underlying theory of the identification of the synchronous generator model with a focus on the calculation of the capability limits in the P–Q diagram. Furthermore, a computationally efficient method for the representation of capability limits suitable for the implementation within the industrial automation and control system of the power-plant is described in detail. Finally, the capability diagrams for three generators were implemented in the power-plant supervisory control and data acquisition system (SCADA) system.

Utilization of synchronous generators on micro-hydro Power plant (PLTMH) need direct monitoring with some parameters such as voltage and current. From the results of the monitoring, the information can be obtained whether the synchronous generator installation is appropriate and produce the expected output power. In some studies, the results of current and voltage measurements are still done by manual use of multimeter, so that the data obtained can not be recorded continuously. The purpose of this research is to create a monitoring system on synchronous generators using arduino-based data logger. Monitoring system using data logger is equipped with timing system. Based on the research that has been done can be concluded that the monitoring system on synchronous generators using arduino-based data logger can record current, voltage, and power in real time resulting from generator performance and then record or save the data into the form of CSV file (comma separated values) every 2 seconds into the micro SD and the data can be displayed through Microsoft Office software namely Microsoft Excel.

This paper describes the vibration condition monitoring diagnosis system developed for stator and rotor winding integrity assessment of 100MW class gas turbine generator in combined-cycle thermal power plant. High reliability of windings is one of the most essential prerequisite for generators of power utilities. Assessing the condition of stator winding insulation systems requires objective information from condition monitoring system. In-service monitoring is essential if a power plant is following a condition-based maintenance strategy. Generator damages are caused by the high vibration and the power system instability by secondary impacts of an unannounced plant stop and the life of the generator is decreased. The mechanical vibration in generator is induced by both mechanical and magnetic forces. The vibration condition monitoring system is required for the improved savings of operation and maintenance cost in terms of reliability in power plant.
