Taiwan Power Company (TPC) Linkou Power Plant Units 1 and 2 are high-efficiency 600°C-class coal-fired ultra-supercritical pressure power generation units that were renewed from the existing units. They have commenced commercial operation as a stable power source in Taiwan, where the power demand has been increasing year after year. Units 1 and 2 adopt steam temperature control, which further improves the stability of the boiler outlet steam temperature and facilitates tuning. Furthermore, a new system featuring Artificial Intelligence (AI) is under development for the purpose of performing automatic combustion tuning of the boiler. The new system is utilized in Unit 2 and confirmed availability. MHPS is making further improvement in its precision, as well as further advancement of the AI performance.
