The planning, design, and operation of industrial and commercial power systems require engineering studies to evaluate existing and proposed system performance, reliability, safety, and economics. Studies, properly conceived and conducted, are a cost-effective way to prevent surprises and to optimize equipment selection. In the design stage, the studies identify and avoid potential deficiencies in the system before it goes into operation. In existing systems, the studies help locate the cause of equipment failure and misoperation and determine corrective measures for improving system performance.
The use of digital computers makes it possible to study the performance of proposed and actual systems under many operating conditions. Answers to many questions regarding the impact of expansion on the system, short-circuit capacity, stability, load distribution, etc., can be intelligently and economically obtained.
