Digital filter simulation for development of digital flickermeter

Abstract

The number of the non-linear equipments connected to the electrical energy distribution system is rising continuously. These equipments generate harmonic currents and voltages in the network impedances and they are added to the base signal deforming the value and the shape of the main voltage. The distorted voltage increases electrical strain and temperature load of the equipment connected to the network. Moreover some of the disturbances can be dangerous not just for the equipments but for the people as well through the lights causing weariness, irritableness, etc. This special, dangerous on people effect is called flicker.
