| Résumé : | Local distribution companies (LDCs) require disconnection of distributed generation (DG) as soon as disturbance events occur to prevent sustainable islanding and damaging DGs and other equipments. In this paper, real-time laboratory testings were carried out to evaluate existing anti-islanding detection schemes. A comprehensive analysis and a testing process are proposed to assess the selection of a fast and reliable scheme for a practical radial distribution system equipped with a group of self-excited induction generator wind turbines (SEIG). Two anti-islanding schemes (passive local detection and communication based) were examined on various commercial relays to disconnect SEIG-DG in case of a main breaker opening due to a fault. The impact of existing recloser timer characteristics on the selection of the proper scheme is illustrated. The selected scheme was verified to disconnect SEIG-DGs in case of a manual main breaker opening in a proper time to protect public safety. A dedicated fiber optic connection and radio frequency communication-based schemes were evaluated and compared with passive local detection scheme performance. Various scenarios of SEIG-DG penetration levels were simulated, and different available commercial relay functions were tested. The obtained results, recommendations, and economic evaluations for choosing a proper scheme are reported and discussed. |
