| Summary: | The purpose of this study is to investigate the optimum deadtime for 275kV auto-recloser that improves the performance of 275kV Kolopis-Segaliud Sabah Grid Transmission Line. The outcome from this study has confirmed the optimum deadtime for 275kV auto-recloser through simulation using PSCAD Software. The 275kV Segaliud-Kolopis Sabah Grid Transmission Line was modelled in PSCAD Software in order to mimic the actual system, thus analysis of deadtime for 275kV auto-recloser was able to be performed. Several conditions were considered which was grouped into three cases. The conditions considered were intended to allow analysis on operation of auto-recloser with regards to absence and presence of fault, and various value of deadtime. Simulation results indicated the success of the auto-reclose to perform reclosing mechanism when fault detected and then cleared from the system in accordance with stipulated performance criteria. Thus, the optimum deadtime is confirmed through, firstly calculation, and then simulation, that is 365ms. Although, the outcome from this study can be implemented directly, provided approval from relevant authority, it has been suggested that further study to be conducted in order to ensure the success of the implementation. |
