When only measurements at the source of flicker are available, flicker levels in other network nodes can be obtained with stationary calculation methods. When dealing with multiple flicker sources it is vital to assess their cumulative contribution to flickers levels in network nodes using flicker summation factors. The paper presents a case of two arc furnaces causing flicker in a particular node...
Stationary and dynamic flicker calculation methods are often used for assessing flicker levels throughout the network. This paper introduces a method for calculating flicker levels in the network by analyzing the propagation of voltage interharmonics. Calculated flicker levels are compared with the measurement results. Simplifications of this method are tested on numerous examples.
The present paper introduces some simulation methods for flicker propagation assessment. The first method is based on current injection into the system matrix of the studied grid. Only one computation is enough to get all nodal voltages of the grid. We can thus deduce flicker propagation coefficient between any two nodes by the ratio of the relative nodal voltages. The second method requires two load-flow...
