Electromagnetic compatibility standards and guidelines used for planning of flicker allocation at various busbars of a power system requires some knowledge of the manner in which voltage fluctuations and hence the flicker propagate and how various loads respond to them. The current rudimentary approach taken for the determination of the load response to voltage fluctuations is based on network impedance values and hypothetical dynamic impedance values of the connected loads. Practical results and recently developed theory on the subsynchronous behavior of induction machines suggest that where there is a large base of induction machine exists on a power system the flicker attenuation is significant. This paper reports on a methodology to include the influence of induction machine behavior in flicker propagation and attenuation studies. The work is based on small-signal models to describe induction machine and system behavior which are utilized for the development of a flicker transfer coefficient. A systematic approach for the practical application of the methodology for flicker related work is included.
