Computer for automatizing network analyzer operation

THE recent activity and interest in the development of computer methods for speeding up the solution time for power-system transient-stability problems has prompted the reporting of some work done on the Massachusetts Institute of Technology (MIT) network analyzer. The idea of coupling a computing device to a network analyzer for solving the electromechanical differential equations of the synchronous machine rotor positions following a fault or other large disturbances to the system is certainly not a new one. Many people have considered the idea and have concluded that the problem is not one of concept but of constructing and instrumenting a computing system which would fulfill all of the operational and economic requirements of the network analyzer service.
