Control Systems

Control systems have become key devices in the handling of enormous volumes of process information as well as local device information. This has created the need for control systems to strike a balance between openness and high security in order to work with higher level systems and achieve optimum operation.

Mitsubishi Power has developed and supplied control systems that maintain high reliability and utilization rates while meeting maintenance support and safety requirements at power plants over several decades and throughout the lifecycle of machinery and equipment.

Controls Upgrade Adds Resiliency & Flexibility

Enel Generación Costanera is the largest thermal power plant in Argentina. ENEL viewed the upgrade of the Costanera GTCC DCS and power block control systems as a key enabler for
digitalization required to support decarbonization, the increased penetration of renewables and long-term sustainability. The challenge was how to implement the upgrade in a preplanned and phased manner that had the least disruption to normal plant operation.
