Power Quality Standards and Requirements

  • Zbigniew Lubosny
Part of the Power Systems book series (POWSYS)

Abstract

The aim of an electric power system is to produce and deliver to the consumers electric energy of defined parameters (power quality), where the main quantities describing the electric energy are the voltage and frequency. The power system (in fact the distribution companies) should ensure the continuous supply of the consumers’ terminals, where the voltage should be a sinusoidal wave with nominal amplitude (e.g. 311 V in a LV system) and a frequency of 50 Hz.

    Power quality problem is defined [20] as any problem manifested in voltage, current or frequency deviations that resule in failure or misoperation of customer equipment.Google Scholar

    Neglecting the short-time phenomena in many power quality standards (also in EN 50160 standard) is pointed out as a limitation of the standards.Google Scholar

    This characteristic is shown as an example for an LV system. In the standard, the flicker severity levels assessment procedure does not in general use the characteristic in an explicit form.Google Scholar
