  1. 1. Embedded digital filter design and implementation

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Xiao Su; [2023]
    Keywords : ;

    Abstract : Digital filters have been widely used in signal processing, to reduce or remove unwanted signals of different types, such as noise, and interference, and to enhance or keep desired signals. They are implemented as algorithms on an embedded system (a microcontroller) or a computer.

  3. 2. The impacts of series compensated EHV lines on distance protection, and a proposed new mitigation solution

    University essay from KTH/Elektroteknisk teori och konstruktion

    Author : Syed Arif Ullah Shah; [2017]
    Keywords : Series compensation; metal oxide varistor; voltage inversion; current inversion; sub-synchronous oscillation; quadrilateral characteristic distance relay; digital high-pass filter; Seriekompensation; metalloxidvaristor; spänningsinversion; ströminversion; subsynkron oscillation; fyrsidig karakteristiskt distansrelä; digitalt högpassfilter;

    Abstract : Series compensation is extensively applied to the transmission lines to increase the power transfer capability of transmission lines, reduce transmission losses, improve voltage profiles, and improve power oscillation damping and transient stability of power systems. But it modifies the apparent impedance of the transmission lines during fault conditions and might cause the distance protection of transmission lines to encounter directional discrimination issues and reach problems.

  4. 3. Design of Harmonic Filters for Renewable Energy Applications

    University essay from Institutionen för kultur, energi och miljö

    Author : Bhunesh Kumar; [2011]
    Keywords : Digital Filter; Impulse Response; Wave Digital Filter; Circulator-Tree WAVE Digital Filter; Harmonics Filter; Renewable energy Filter; Wind Energy Filter; Butterworth; Chebyshev and Cauer filters; Low-pass; High-pass and Band-pass filters;

    Abstract : Harmonics are created by non-linear devices connected to the power system. Power system harmonics are multiples of the fundamental power system frequency and these harmonic frequencies can create distorted voltages and currents. Distortion of voltages and currents can affect the power system adversely causing power quality problems. READ MORE
