The results clearly show the effectiveness of proposed design method in harmonics elimination and power factor correction. Finally, the performance of the design algorithm is tested for a 6-pulse HVDC converter simulated on the MATLAB.
Probably the most popular is the double-tuned filter (depicted in Figure F. Using this method, the parameters of damped-type double tuned filters are calculated based on the tuned frequencies, the parallel resonance frequency, and the reactive power compensation capacity etc. This component can be used in to model high-order filters. Next, the proposed design algorithm is developed for damped-typed double tuned filters. Simple 2D rendering allows rapid layout design while obstacles and banks can be tuned in 3D mode. Abstract: The ac/dc filters are always needed in HVDC converter stations to suppress harmonic. Firstly, the conventional double tuned filters are comprehensively studied, and an algorithm for precisely determining the parameters of this type of filters is presented. R/C Track Designer is a simple 2D/3D program to assist radio controlled racing hobbyists in designing on-road and off-road race track layouts. Damped-type double tuned filters design for HVDC systems. It can generally be built and adjusted without access to expensive equipment such as spectrum analysers or network analysers. Over the years I have found it to work reliably. This paper presents an algorithm for design of the conventional and damped-type double tuned filters to reduce harmonic distortion and improve power factor in electrical systems. Aiming at the question of parameter of double-tuned filter, A new method of designing double-tuned filter was proposed based on resonance frequency. The double-tuned-circuit band pass filter topology was chosen for this QRP Labs bandpass filter kit because it is a popular, tried and tested design. Among different types of filters, double tuned passive filters have been widely utilized in HVDC stations, yet these filters are still not considered well developed. Figure 1: A simple double-tuned band-pass filter without any additional matching of R L to the system impedance. Without elaborating on its design, assume that we have selected design parameters and components that result in R L 2000 ohms.
Please read the kit-building instructions (see below) for more details on the circuit, design trade-offs, construction. Figure 1 shows a double-tuned bandpass filter structure. It has a 50-ohm input and output impedance. The kit can therefore be used with our relay-switched filter kit. The ac side filters are also employed to compensate network requested reactive power. The Band Pass Filter kit is the same size as our LPF kit, 1.5 x 0.5 inches (38.1 x 12.7mm). The ac/dc filters are always needed in HVDC converter stations to suppress harmonic currents/voltages.
