Adaptation de la procédure SSFR aux exigences industrielles
|Abstract:||Generator models validity is essential to analyze power grids stability and dynamic performance. Energy producers must provide power carriers with the model parameters of all generators commissioned after 1990. The parameters supplied must be validated by experimental measurements. In North America, the most accepted parameter estimation procedure is the short-circuit test. For repair cases, the high risk of damaging the alternator may become unacceptable. The SSFR (« Standstill Frequency Response ») test described in the ANSI / IEEE Std 115-2009 standard has several advantages over more traditional methods, namely an improvement of the models accuracy over a wider bandwidth (> 200 Hz) and the elimination of the risk of damaging the generator. The research project objective is to develop an automated measurement system meeting industrial constraints in order to assist the realization of the SSFR test on large hydraulic alternators. The proposed solution aims to maximize the quality of measurements while minimizing the number of manual interventions and the complexity of the experimental setup. The system has been used for more than two thousand hours to perform validation tests on 5.4 kVA generators. The tests demonstrated that the system is robust and has the required specifications to perform SSFR tests that meet the requirements of the ANSI / IEEE Std 115-2009 standard. The first three chapters of the thesis introduce the theoretical framework related to the dq0 modelisation of a synchronous generator, then describe the main tests allowing the identification of the model parameters. The second part of the thesis focuses on the various design considerations of the automated measurement system.|
