Using analogue computers in power system studies

IN THE PAST FEW YEARS a great interest has developed in the use of digital computers for solving the engineering problems of utility companies. The utility engineer already was familiar with t h e use of computers such as the network analyzer for power system studies, but many types of problems were encountered which were either long and tedious or impossible of solution on the network analyzer. As digital computers became more available, often because they could be bought or rented for use by both the engineering and accounting staffs, the engineer turned to them as a new tool for solving his problems. In doing this, he often overlooked the new methods that have been developed in analogue computers.
