Abstract

This paper is concerned with the new applications of on line/off line computers in modern power systems. In this paper, computer control from the power stations to the substation and transmission is extended. A new technique using a new topology description is developed. This technique has the facilities of describing topology connections, states, proparties as well as the optimal process of power stations. A program is constructed and used for performing the system interlocking. The Egyptian 500kv substation is checked by the proposed technique and its prospective program. The on-line interlocking is found to have less computation time than the off-line interlocking. The off-line computer is applied for determining the stability of the 500kv portion of Egyptian grid.
