“…The advantages of double-tuned filters include the need for only one circuit breaker per phase, less space, the simplicity of the circuit schematic, less maintenance, and last but not least, the double-tuned filters significantly lower cost when compared to active filters [34]. Additionally, a double-tuned filter's THD measurement is 0.91% [35]. When the system impedance reaches the filter impedance in a typical double-tuned filter, the harmonics become amplified, resulting in significant harmonic distortion.…”

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.
