Integrated electrical control and monitoring system via IEC61850, IEC60870 and DNP3.0

Safety Control Station (SCS)

Field Control Station (FCS)

Plant information managementAll types of plant information including process data, alarms, events and sequence of events (SOE) are handled by plant information management, enabling the analysis of plant operational performance.

Plant resourcemanagementPlant resource management integrates and manages maintenance information from field instruments and monitors online conditions.

The ProSafe-RS SCS is a TÜV SIL3 certified safety system that incorporates Yokogawa’s own pair-and-spare technology.

Turbine Control SolutionsSince delivering the world’s first distributed control system (DCS) in 1975, Yokogawa has supplied globally more than 30,000 DCSs of unsurpassed reliability and availability for control and protection. Today, Yokogawa’s turbine control solutions are used for a wide range of turbines from small to large utility steam turbines, boiler feed pump turbines, industrial gas turbines, mechanical drive turbines, hydro turbines, wind turbines, synchronous modifiers, and more.

Integrated platform for the entire plantAn integrated system enables seamless operation via a common interface for an entire power plant encompassing the boilers, burner management systems, balance of plant, and turbine systems. Servo and protection modules handle the critical turbine control together with standard DCS hardware, while Yokogawa’s safety system protects the turbine. In terms of security, ISASecure-certified controllers ensure safe operation.

Project executionYokogawa is highly experienced in projects to retrofit mechanical turbine governors and dedicated controllers for turbine control. Supply, installation and commissioning encompass speed sensors, their brackets, hydraulic trip block systems, hydraulic actuators, oil filters, turbine supervisory instrumentation, synchronizers, automatic voltage regulators and oil purification systems. Even when replacing equipment supplied by the turbine manufacturer as part of the turbine units, Yokogawa can successfully upgrade obsolete controls to leading-edge systems.

For new generation units, we are experienced in implementing turbine protection and control functions for their respective turbine suppliers to realize integrated power plant control systems for users.

Extensive support for secure operationOur 230 local service offices in 80 countries offer extensive support for users. Through your nearest service office, Yokogawa can provide cost-effective service and maintenance spares for both plant and turbine control systems. Above all, as the world’s pioneer of DCSs, Yokogawa supports both plant and turbine control systems over the long term, keeping your systems up to date and protected against malicious cyberattacks as the world evolves.
