The advanced monitoring and operation system is achieved through the application of knowledge engineering and human-machine engineering.
Besides, improved facility maintenance support is achieved by integrating with a management information system and facility maintenance system.
Wide range of functions including an integrated maintenance service are available.(e.g. a monitor screen with integrated logic drawing via CAD, a hierarchical control logic structure and simulation and trend functions.)
Power plant information is integrated through a large-capacity and high-speed real-time network.
This system is designed in such a way as to incorporate both old and new equipments enabling advanced operation and increased system lifespan by the renewal of existing system components as required.
Since an autonomous interlock protection function, operating even in isolation of a controller, is included, this represents an intelligent PI/O , which allows the hardware circuit volume to be greatly reduced.
The number of field cables can be greatly reduced by the use of a distributed I/O.
