Differential analyzer aids design of electrical utility automatic dispatching system

THIS PAPER encompasses two important aspects of the 1957 symposium theme of ¿Computers in Control.¿ First, the General Electric Automatic Dispatching System1¿3 to be described includes analog computing loops which insure that the turbine generators within the utility system are loaded according to incremental cost theories, thus resulting in minimum fuel expenditures for the utility system. Second, the application of a differential analyzer as a tool in the design of this automatic dispatching system will be described. The differential analyzer application may be outlined as follows: 1. Complete differential analyzer simulation of power system and dispatching system to determine optimum design of regulating and economic loops. 2. Differential analyzer simulation of power system tied together with prototype control components to study and evaluate the design of prototype equipment.
