An experimental electronic power-system simulator

The problem of power-system simulation is approached by considering the system as an integrated physical interconnection of generators, transmission network and load. In this way a freedom of design ensues which would not be possible if the work were identified with the need to render existing network analysers automatic. A d.c. electronic analogue computer for synchronous-machine representation which invokes the minimum number of assumptions is coupled to a high-frequency impedance analogue for the transmission network, to form a composite system simulator. To facilitate the study of simulation techniques the power system is reduced to the basic two-machine configuration. This preserves the essential characteristics of a synchronous system and ensures that the techniques will be applicable to a multi-machine simulator. The paper describes the simulator and concludes with some solutions of representative problems.
