Design and Testing of an TCSC for Distribution Network Applications

Connection of distributed generator (DG) into very weak points of the electricity distribution network is increasing. These connections impose many operational issues and therefore utilities restrict DG connections to the grid. In this study an application of thyristor controlled series compensator (TCSC) to overcome some of these issues are investigated, especially voltage control at the point of connection and its fault limiting capability. The TCSC was designed for a prototype network and implemented in the laboratory. The expected performance of the model was investigated with PSCAD/EMTDCcopy simulation and verified with experimental results. Application of an TCSC with a distributed generator (DG) for a real scale network was studies using PSCAD/EMTDC simulation to investigate the performance of the TCSC as FCL and series compensator
