Power-System Analysis: What It Can Do for Industrial Plants

Power-system analysis primarily consists of the techniques used to predict or improve the performance of an existing or proposed power system under specified conditions. These Techniques, when applied to industrial power systems, can contribute heavily to fulfillment of the goals of industrial-system design, such as safety, reliable service, high-power quality, and low initial and operating costs. Principal types of industrial-system studies include short circuit, protective device coordination, load flow, transient stability, motor starting, grounding, transient overvoltage, power-factor improvement, and miscellaneous design and application studies including combinations of the above. Power-system analysis should be applied whenever a new or revamped power system is being planned, when the load or capacity of an existing system is markedly changed, or when the existing system requires trouble-shooting.
