This paper presents an overview of assessment techniques recommended by IEEE Std 519-1992 and the EuroNorm 50160-2009. It also examines reporting requirements for harmonic distortion and voltage fluctuations by the Norwegian NVE 1557 and the Colombian CREG 047 regulations. The paper also presents typical values for harmonic distortion and voltage fluctuations from the three electric utility distribution...
For continuous applications of distributed power, such as photovoltaic power and wind power and so on, power quality of public distribution network faced more uncertain factors, performance of power quality compensation equipments in distribution network like shunt hybrid active power filter (SHAPF) also suffered from some negative influences of distributed power, so their control strategies were...
This paper first analyzes the Park transform and Clarke transform of 5 normal power quality disturbances and then proposes 3 characteristic indexes based on the two transforms. The indexes can be used to classify 5 single disturbances and 5 mixed disturbances exactly. The algorithm is simple and easy to be implemented by hardware. It can also be the basis of power quality index evaluation. At last,...
