摘要
This letter introduces representative voltage samples that, together with flicker transfer factors, enable the calculation of flicker levels throughout the network at the same voltage level. The described method is an alternative to the established stationary flicker propagation methods. The shorter 1-s voltage samples are extracted from the instantaneous voltages measured and can represent the longer operating periods of an arc furnace. The calculation of flicker levels with the use of voltage samples is practical and eliminates the need for flicker measurements in an arbitrary network node. In addition, the flicker levels in nodes under the influence of flicker from multiple arc furnaces can be obtained without the use of superposition factors.
