    Abstract : With the advent of Industry 4.0 and the Internet of Things, collecting data on Cyber-Physical systems has become the norm practice in large scale industries. By collectingrelevant data, it is possible to monitor the health status of whole systems or specificcomponents within them. READ MORE

  3. 2. Developing Verification Models for Corona Discharge Suppression in High Voltage Capacitor Banks

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Mohammadjavad Javadi; [2020]
    Keywords : Corona discharge; Suppression ring; High voltage capacitor banks;

    Abstract : Due to the universal considerable population and economic growth rate, demands for energy have risen significantly over the past decade. This means that the integration of renewable energies in the power grid has escalated as well as requests for reactive power compensation, voltage stability, and mitigation of harmonic filters.

  5. 4. Mitigation of Background Harmonic Amplification at PCC Using Active Filtering of STATCOM

    University essay from KTH/Elkraftteknik

    Author : Luai Malki; [2017]
    Keywords : FACTS; Hybrid-STATCOM; TSC; TSR; VSC; passive filter; active filter; PWM; MMC; passivity; input admittance; resonance; harmonics; ABB;

    Abstract : Shunt compensation devices have been a powerful candidate for expanding the limits of transmission facilities, allowing more active power transport and supporting voltage and overall stability of the network. An example of such devices is the Static Synchronous Compensator (STATCOM) which is based on Voltage Source Converter (VSC) which synthesizes output voltage and current for mainly reactive power compensation.

  6. 5. Ammonium and orthophosphate ions removal from source separated human urine using dual reactive filters: A small scale laboratory study in a batch mode.

    University essay from KTH/Mark- och vattenteknik

    Author : Prayash Khanal; [2013]
    Keywords : Reactive filters system; Urine; Nutrients removal; Polonite; Mordenite; Batch mode;

    Abstract : The nutrients available in urine make it a good resource as fertilizer. Limited availability of natural phosphorus (P) is compelling people to think about recovering and returning it back to the land from waste stream. READ MORE
