An Automatic Dispatching System

The factors involved in the design of an automatic dispatching system are discussed in detail in order to establish the background common to the dispatching operations of all-electric utility systems. It is the aim of this paper to review all the factors involved and to supply the systemplanning engineer with information to be used in arriving at an appropriate control for his specific system. An automatic dispatching system based on the principles outlined is shown in block diagram form and its operation is described. The description includes an account of dispatching procedures for an operation using the system shown in the block diagrams. A description of emergency measures and protective facilities is also included.
