PROJECT TITLE :
Development of frequency-based anti-islanding protection models for synchronous distributed generators suitable for real-time simulations
This study proposes simulation and analytical models of frequency-primarily based protection functions (beneath and over frequency, rate of amendment of frequency and vector surge) used to detect islanding of synchronous distributed generators. All relay models are validated by using the concept of performance curves and two commercial relays. By using the performance curves, it is possible to make a comparison between the models and the industrial relays for a large variety of islanding things. Yet, the simulation models are appropriate for real-time analysis. A real time digital simulator operating in a closed-loop mode is used to run the simulations and information acquisition. The results indicate that the models and business relays gift a similar behaviour, showing that the models can properly simulate the commercial relays for islanding detection analyses of distributed generators, being acceptably accurate.
