Among all electric disturbances, flicker is not the most harmful one resulting in malfunction of grid equipment and customer appliances, because flicker phenomena is evidently visible, all twinkling lamps may lead to often LV customer complaints. For utilities, flicker estimation is one of the necessary tasks in assessment of emission level for the connection of fluctuating installations to electric...
Under the scope of the IEC technical report 61000-3-7, the principles to assess flicker emission limits for the connection of fluctuating loads to the public network power system have been outlined. This technical report gives also the definition of the flicker emission level. But this report does not explain how to measure and assess the flicker emission level. Actually, because of the existence...
This paper presents a methodology for flicker propagation analysis, numeric IEC flickermeter emulation and flicker source modeling. The main results of this study are: ldr To create a distribution load model by which the flicker propagation from HV to MV can be studied, ldr To build numeric IEC flickermeter with improved algorithm (demodulator and nonlinear classification), ldr To build simplified...
