Improvement of Transient Stability of the Power Grids by a Judicious Auto-Reclosing Scheme in the Presence of Synchronous-Based DGs

Conference Paper


Abstract


  • This research paper proposes an adaptive reclosing mechanism to preserve the network stability in post-fault scenarios for the power grids equipped with synchronous-based distributed generation (SBDG). The proposed adaptive reclosing scheme will utilize the extracted fault location information for the classification of the fault events in reclosing or block reclosing zones (BRZs). Furthermore, this intelligent reclosing scheme will ensure safe and stable network operation by preventing hazardous reclosing attempts against persistent faults in forestry/bushes areas such as in Australia. The swift fault removal by the associated protective devices (PDs) will assist in ensuring the stable operation of the SBDG. The adaption of the proposed scheme will allow the reclosing at an appropriate instant to preserve the network stability against momentary faults. However, it will also ensure quick fault clearance by permitting the associated PD to directly operate against the permanent faults. The validation of the proposed protection strategy has been carried out on the IEEE standardized test system to demonstrate its effectiveness in comparison with the conventional reclosing practices.
