Digital Excitation Control System: 44 Iiee Manila Philippines

The document discusses upgrading aging excitation control systems with a new digital excitation control system called DECS-2100. It outlines reasons for upgrading such as degradation, mechanical issues, maintenance requirements, reliability impacts, and component obsolescence. It then describes the features of DECS-2100 including operating modes, limiters, monitoring tools, protection, and communication capabilities. The document also provides examples of DECS-2100 installations in the Philippines, Singapore, and Thailand.
