THE CHEAPEST WAY TO SOLVE THE FLICKER PROBLEM

摘要

Measurements during the last eight years show an increasing level of P{sub}(It), an indicator used for the flicker level. Furthermore, almost 50% of all technical customer complaints are flicker problems. The short-circuit power on the connection point is a very important parameter for controlling the fast voltage variations that lead to flicker. However, a high short circuit level can not be established unless investments in the low voltage grid are made. Analyzing the database of customers complaints shows that in only 25% of all cases the short-circuit power is less than the minimum value given in the national grid code, as indication. So other solutions, without investment in the network, are needed.
