Abstract
A Station Service Distribution System (SSDS) plays an important role in a hydroelectric generating station. It provides a reliable power source to feed various loads inside a generating station. Throughout years of operation, SSDS equipment could fail due to aging, and replacement parts may not be readily available. The utilities are, therefore, facing many challenges in maintaining the SSDS system availability and protecting the safety of the site personnel in generating stations.
This thesis proposes an effective approach and several methodologies to resolve the engineering challenges related to retrofitting an existing station service distribution system in a hydroelectrical generating station. The approach does not follow the traditional technical path, but rather a techno-economic method considering system robustness, operation cost, and safety from a long-term point of view. The approach and methodologies developed in this thesis are evaluated in a case study to validate their applicability.
Conclusions show that the developed approach and methodologies effectively improve the station service distribution system in a hydroelectrical generating station. The same approach and methodologies can be applied to any generating stations facing with similar issues.
