Development of Power System Simulator for Research and Education

A power system simulator called Transient Network Simulator (TNS) was installed in April 1988 at the Electrical Engineering Laboratory of the School of Sience and Engineering, Waseda University, for laboratory work for both undergraduate and postgraduate courses and for R & D purposes. This version of TNS has been designed and manufactured according to the specifications supplied by Waseda University by adding features (a structure consisting of power system block and digital control block) to the prototype of TNS which has been used for research and development purposes in Fuji Electric, Ltd. The transmission line and transformer are implemented with passive analog devices; the generator with active analog devices; and the load with hybrid devices. These devices are controlled by programmable controllers. This simulator is the modernized successor, so to speak, of an AC network analyzer (1965–1975), and two artificial transmission lines (1925–1945), and (1960–1986).
