A small hydro power (SHP) system in Taiwan using outlet-water energy of a reservoir: System introduction and measured results

This paper introduces a small hydro power (SHP) system using outlet-water energy of a reservoir in southern Taiwan. The rated capacity of this SHP system is 8.75 MW and the generated power is delivered to the 69-kV system of Taiwan Power Company (TPC). Since the studied Reservoir Wushantou with abundant water offers available water for irrigation of farmlands, industry, people´s livelihood, etc., the generated power of the SHP system is very stable and continuous as comparing with the intermittent generated powers from wind turbine generators and photovoltaic arrays. The studied SHP plant is also one of the investments of the multiple managed businesses of the largest farmland irrigation association in Taiwan, Chia-Nan Farmland Irrigation Association. This paper presents some details of the finished SHP system including engineering, electricity prices, capital cost, revenue of power generation, etc. Some measured results of the SHP system including harmonics and flickers are also demonstrated.
