Energy saving start-up strategy of pumped storage power plant equipped with doubly-fed asynchronous machine

Abstract

Pumped storage hydro power plant with doubly fed asynchronous machine offers impressive features and provide flexibility in operation. In pumped storage power plant, the starting method of doubly fed asynchronous machine is similar to the conventional asynchronous machine, where a substantial amount of energy is wasted. This paper proposes an effective energy loss reduction technique to the doubly fed asynchronous machine based system during starting. The proposed start-up strategy is modeled and simulated using MATLAB SIMULINK software with the experimental validation. Also a detailed comparative analysis is carried out between the existing method and the proposed strategy in this paper.
