Abstract
Hydropower is considered best option among all the power generation techniques from the view point of its renewable nature, low running cost and environment friendly nature. The four major components of the generators identified are stator winding, stator core, rotor, mechanical components and external factors. In this study, the stator core which is a main component of a generator has been considered for condition evaluation/monitoring. This study presents a new and noble empirical technique for the evaluation of the condition of the hydro generators. The main aspects of hydro generator stator have been taken into consideration for condition evaluation of stator core. A new approach known as multi-criterion analysis for assessing the condition of generator has been proposed and accordingly decision can be taken by utility managers for its rehabilitation. The various factors influencing the performance of stator core of a generator have been further classified in their sub-components and have been given scores and depending upon the score of individual sub-components owing to their condition, possible conditions have been calculated. These calculated factors implies that which type of rehabilitation approach needs to be implemented for optimal performance of the machine also, it results in extended life of the equipment.
