Abstract

This paper presents the study of the optimal turbine set for pumped hydro-storage power plant at Chulabhorn Dam, Thailand. Ten sets of 1,200 MW turbines were investigated with three types of turbines: fixed speed (FIX), variable-speed Doubly Fed Induction Machines (DF), and variable-speed Synchronous Machines Equipped with Full Size Frequency Converter (FULL). The objective to find the best set of turbines with highest efficiency and flexibility was selected for the plant, based on electricity consumption of the Northeast over the past one year. The efficiency and the flexibility are computed from a characteristic curve of each other type of turbine. As a result, the top three sets is set 2 (FULL,FULL, FULL) set 8 (FULL,FULL,DF) and set 9 (DF,DF,FULL), respectively.
