Alstom fully automates Keppel and Tuas power plants

Keppel Merlimau Cogen and Tuas Power both selected the Alstom ALSPA Series 6 integrated control system as part of their EPC contracts. It includes gas and steam turbines controls, and Monitoring & Diagnostic System.

ALSPA system integrates common hardware on a single platform to help reduce maintenance, spare parts and training costs for the plant operators.

The competitive nature of the power market in Singapore increasingly dictates the use of modern flexible control system architectures, combined with advanced decision support applications for optimising power generation.

Alstom’s ALSPA® Series 6 power plant automation application provided to both the Keppel & Tuas power plants is a complete and powerful Distributed Control System that is particularly well adapted to Combined Cycle power plants requiring the highest availability and performance capabilities. Based on high-end technologies and advanced control functions, together with with the ALSPA Human Machine Interface and plant optimization software suite, the ALSPA DCS will enable KMC & TPG to operate in a flexible environment.

In addition, KMC also decided to include the ALSPA Series 6 plant simulator into their contract. This state-of-the-art simulator is integrated with online plant management facilities to assist operators in making decisions about changing how a plant operates. Depending on the scenario (e.g. considering fuel costs and power sales), running a ‘What if’ simulation can help an operator decide on whether to start, stop, increase or reduce load, or to plan/postpone a preventive maintenance outage, thus maximising the plant’s full potential in a competitive power market such as Singapore.
