Rapid growth of power quality problems
Before the application of computers and solid state electronics equipment, power quality problems were nonexistent. The quality of power was primarily judged by specified general characteristics such as voltage, frequency, voltage regulation and power factor. Present day electronic loads that process intelligence (computers, communications, etc.) rather than power (adjustable speed drives, electroplating rectifiers, etc.) have a common denominator. Incoming power experiences the equipment DC power supply which converts high AC voltage to low DC voltage. AC power quality problems are primarily disturbances that can be summarized as spikes, dips, sags, swells. harmonics, surges, over-voltage, under-voltage, brown out, EML RFL waveshape distortion, glitches, hits, outage and many others. By the century`s end, it is estimated that electronics loads will consume 60% or more of total generating capacity. Our economy will then be heavily dependent on power quality. This paper focuses on engineering guidelines of finding possible solutions to the power quality problems.
