PRESS RETURN TO CONTINUE. 

THIS PROGRAM EVALUATES A BALANCED THREE-PHASE POWER
SYSTEM SUBJECTED TO A DISTURBANCE. THE FOLLOWING
QUANTITIES ARE COMPUTED FOR EACH DISCRETE TIME: 
     (1) POWER ANGLE OF EACH SYNCHRONOUS MACHINE
     (2) FREQUENCY OF EACH SYNCHRONOUS MACHINE
     (3) REAL POWER OUTPUT OF EACH SYNCHRONOUS MACHINE
     (4) VOLTAGE MAGNITUDE AT EACH BUS

BEFORE YOU CAN RUN THIS PROGRAM
YOU MUST FIRST RUN THE POWER FLOW PROGRAM THAT IS
ON THIS DISK FOR YOUR POWER SYSTEM.
