Practical Studies on Power System Operation and Switching by Power System Simulator

The electric power system in Japan has been getting complicated and will continue to grow in the future. Along with the modernization of other industries, there is still a further need for the improvement of the service quality of electric power supplies. It is generally recognized that the conventional manual system operation or local system control has reached its technical limits. For this reason, the present days´ emergent need is to establish an automatic load dispatching system including a central control computer capable of performing integrated system operation. The power system simulator has been designed and constructed to solve a variety of technical problems associated with integrated system operation. The design conception and specifications of the power system simulator is described briefly. An outline of several research programs presently under development is also included.
