Continued evolution of networking and PC technologies has enabled better integration of control center systems and driven down operating costs. By employing low-cost-high performance PC servers, we can anticipate new load dispatching control systems implemented at substantially lower development cost. Especially in the current fluid and rapidly changing environment faced by the power industry, these new load dispatching control systems can be readily tailored to flexibly accommodate whatever operating structural changes emerge in the years ahead. These were the circumstances motivating the Hitachi Group to develop integrated SCADA (supervisory control and data acquisition) systems interconnected over WANs (wide area networks). This is the first time such a system has been developed in Japan featuring WANs-interconnected substation controller and PC servers running the Linux* operating system. The new integrated WANs-interconnected SCADA systems have now been deployed at The Kansai Electric Power Co., Inc.'s Tokai Load Dispatching Center.
