At thermal power stations that have been operating more than 10 years since the start of operations, there are cases in which plans are being made for the renovation of control equipment, from the point of view of preventive maintenance. These renovations do not simply mean replacing functions on existing equipment; in many cases, the goal is to improve upon existing functions through the application of the latest information systems technologies. From an economic standpoint as well, many users are actively promoting the rationalization of cable construction and control equipment through these renovations as a means of minimizing costs. In order to respond to these types of renovation plans, Hitachi developed a supervisory and control system and applied it to renovations in the control systems of a thermal power station. Through the adoption of four main elements - (1) CRT operations; (2) a shift to printed circuit board for relay circuits; (3) remote I/O (input and output); and (4) CAD-based software maintenance tools - this system ensures ease of maintenance, operability, and reliability, without sacrificing economy. Hitachi will apply these results in a broad range of areas, including the latest thermal power stations, while at the same time promoting downsizing and other activities aimed toward the construction of systems with even greater economy and reliability.
