“…One of the most important issues in the practical realization of active power filters and hybrid active power filters is the reduction of the time delay in the control system [64][65][66]. The time delay results from digital implementation of the control system and the usage of analogue filters in measurements.…”

The paper presents a shunt hybrid active power filter for 1 kV mining applications in configuration with a single-tuned passive filter. The focus is on the method of controlling the filter, with particular emphasis on the influence of network voltage distortion and time delays in control on the effectiveness of harmonic reduction, which is one of the most important aspect of power quality. The low-power loss configuration of a hybrid filter with SiC transistors is shown, as well as the control algorithm which limits the influence of voltage distortion. Theoretical considerations are verified by results obtained from simulations and tests of the hybrid active power filter prototype.

“…Consequently, research and application of active filter have become more extensive. Various design approaches for active filters have been proposed (Yang et al, 2022;Farghly et al, 2022;Du et al, 2022), addressing aspects such as optimizing the multi-topology structure of passive filters, parallel filtering structures based on hybrid systems, and adopting two-parallel single-tuned LC structures while considering the time-delay effect of controllers. The designed filters can effectively reduce harmonics and simultaneously reduce the size of capacitor banks to reduce reactive power compensation.…”

The AC power system strength exhibits time-varying characteristics during operation, thereby affecting the filtering performance of filters in the system. Failure to account for this variability may result in the harmonic levels exceeding permissible limits under specific power system strength, thereby affecting the normal operation of the power system. Consequently, building upon the existing filtering technique based on parallel-connected fixed capacitors for LCC-HVDC systems, a method for tuning the parameters of parallel-connected capacitors is proposed, thereby the capacitance range meets the filtering requirements under various system strengths.

“…The voltage and reactive power in HVDC systems are controlled using the secant method, a numerical approach. To improve the frequency regulation and damping control of hybrid HVDC power systems, a novel technique known as optimum fuzzy-based controllers has recently been investigated [22][23][24][25].…”

This paper presents a performance analysis of novel doubledamped tuned alternating current (AC) filters in high voltage direct current (HVDC) systems. The proposed double-damped tuned AC filters offer the advantages of improved performance of HVDC systems in terms of better power quality, high power factor, and lower total harmonic distortion (THD). The system under analysis consists of an 878 km long HVDC transmission line connecting converter stations at Matiari and Lahore, two major cities in Pakistan. The main focus of this research is to design a novel AC filter using the equivalent impedance method of two single-tuned and double-damped tuned AC filters. Additionally, the impact of the damping resistor on the AC channel is examined. The THD of the HVDC system with and without current AC filters was also compared in this research and a double-damped tuned AC filter was proposed. The results of the simulation represent that the proposed double-damped tuned AC filter is far smaller in size, offers better power quality, and has a much lower THD compared to the AC filters currently in place in the converter station. The simulation analysis was carried out utilizing power systems computer-aided design (PSCAD) software.
