3 Institute of Control and Industrial Electronics 1.Introduction Warsaw University of Technology Electrical energy is a result of processing as a product should be valued an standardized. The electrical energy quality should be considered on technical categories (physical and technical criteria) and economic categories ( economic and marketing criteria) The term power quality has many different meanings: *A voltage and/or a current or a deviation of frequency from its nominal value, which result in a failure or in the inappropriate operation of energy consumer s equipment, expresses energy quality **Electric energy quality is a set of parameters that describe characteristics of a process of energy delivery to a user under normal operating conditions 1), determine continuity of supply (long and short power interruptions), and describe character of a supply voltage (value, asymmetry, frequency, waveform).- /Advisory Committee on Electromagnetic Compatibility / ***Energy quality is expressed by the degree of user s satisfaction from supply conditions.
4 Institute of Control and Industrial Electronics 2. Power quality evaluation - standards Warsaw University of Technology Standardization of factors, which characterize particular disturbances, is worked out rather well, and contained in IEC rules of series, which are systematically developed. The main indices and values determining the power quality are: voltage magnitude frequency voltage and current harmonics voltage fluctuation voltage dips and short interruptions voltage swells transient over voltage voltage unbalance long supply interruption. To describe harmonic distortion the following factors are used: the individual current harmonics voltage ratio - I Ih 100% I 1 U hr = U h hr = 100% U 1 and the total current and voltage harmonic distortion I = RMS I THD 1 100% = 2 i I 100% 2 I 1 h hr U 2 2 = RMS U THD 1 100% = 2 u U 100% 2 hr U 1 h

21 Institute of Control and Industrial Electronics 4. Summary Warsaw University of Technology No internationally accepted definition of power (energy) quality has been worked out. There still exists some disagreement about energy quality and electromagnetic compatibility, To have possibility of effective influence on harmonics the locations of the harmonic sources should be known, A continuous development of distributing generation causes that as well energy sources as loads have dynamic character, The most efficient way to improve the power quality is using different active power conditioners, A natural and perspective way of improving power quality is building receivers with linear character, consisted of a load and integrated with it appropriate converter, Work at searching and improving renewable energy sources and energy storages should be continued.
