Interharmonics and flickers have an interrelationship between each other. Based on International Electrotechnical Commission (IEC) flicker standard, the critical flicker frequency for a human eye is located at 8.8 Hz. Additionally, eye strains, headaches, and in the worst case seizures may happen due to the critical flicker. Therefore, this paper introduces a worthwhile research gap on the investigation of interrelationship between the amplitudes of the interharmonics and the critical flicker for 50 Hz power system. Consequently, the significant findings obtained in this paper are the amplitudes of two particular interharmonics are able to detect the critical flicker. In this paper, the aforementioned amplitudes are detected by adaptive linear neuron (ADALINE). After that, the critical flicker is detected by substituting the aforesaid amplitudes to the formulas that have been generated in this paper accordingly. Simulation and experimental works are conducted and the accuracy of the proposed algorithm which utilizes ADALINE is similar, as compared to typical Fluke power analyzer. In a nutshell, this simple predictive method for critical flicker detection has strong potential to be applied in any human crowded places (such as offices, shopping complexes, and stadiums) for human healthy precaution purpose due to its simplicity.

Due to non-linear loads or non-linear behaviour of some elements, harmonics currents are injected in the network generating a voltage distortion. To improve the voltage quality, some passive filtering are used to trap these harmonic currents. However a simple passive filter modifies significantly the characteristics of the network by generating a parallel resonance and can create some problems of oscillations and instability when associated with power electronics converters as Large Rectifiers or Static Var Compensator. To avoid these problems, passive damping with parallel resistors is generally introduced. However this technique generates some losses in the whole filter and alters the efficiency of the filtering. This paper shows that dynamic damping with Voltage Source Converter can contribute to improve the damping without altering the filter efficiency and to optimise the whole losses of the hybrid filter. Two industrial cases are presented: Dynamic damping in the case of power supply and dynamic damping in the case of shunt compensation. Extension of this principle in a hybrid filter is presented in this paper with regards on losses and sizing. This article shows the strategic interest of small converters in AC filtering to make it evolute in new techniques associating passive and active elements to form hybrid dynamic damped filter.
