On May 27, 2014, Mr. Vatee Laoharojanaphand an Engineer from the Power Purchase Agreement Division of the Electricity Generating Authority of Thailand (EGAT), presented his research in 2014 Asia-Oceania Regional Council of CIGRE (AORC-CIGRE) Technical Meeting at Arcadia Ichigaya in Tokyo, Japan. The research topic is Examination of Frequency Step Response Test for Primary Frequency Control System of the Generating Units in Nam Ngum 2 Hydro Power Plant. This research is a collaboration between EGAT, the sole power purchaser from Nam Ngum 2 hydro power plant (NNG2) and CK Power public company limited, the owner of NNG2.
The 615-MW Nam Ngum 2 Hydro Power Plant is located 90 kilometers north of the Lao People’s Democratic Republic’s capital city, Vientiane. As the one of four foreign independent power producers in the Lao PDR, this project consists of three 205-MW generating units, with vertical shaft Francis turbines. The power plant is connected to a double circuit of 230 kV transmission line to Nabong substation in Vientiane and Udon Thani 3 Substation in Northeast Thailand. A Concrete-Face Rock-fill Dam that spans across the Nam Ngum River, it contains an approximate 2,994 MCM effective storage reservoir. This project was originated under the Power Purchase Agreement between SouthEast Asia Energy Limited (and later novated to Nam Ngum 2 Power Company Limited) and the Electricity Generating Authority of Thailand in order to supply the electricity to Thailand.
