On Supervisory Control Systems

Abstract

The present paper first descibes general characteristics of the supervisory control systems and classifies those systems developed in Europe and America at present according to the operation and then gives general requirements for the supervisory control system. The paper also gives a general deacription of several existing systems such as Selector, Distributor, Audible, Code Visual, Synchronous Visual, Synchronous Selector and systems using carrier current etc., and some details concerning a system developed by the author which uses automatic telephone relays and rotary switches and in which the selection is made by the mean of the mumber of impulses or their combination. The author's system is applicable to a very large number of power apparatuses scattered or centralized, and is characterized by the particular feature of impulse sending.
In the last part of the paper, some comments are made on the Supervisory control systems described and their relation to tele-metering is also tonched upon.
