1. 1. Damping of sub-synchronous control interactions with a STATCOM : Wind farms & series compensated power lines

   Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

   Författare :Leonardo Alvarez Urrutia; [2022]
   Nyckelord :Sub-Synchronous Control Interactions; Power Systems; STATCOM; Network Stability; Doubly-Fed Induction Generator; Impedance-Based Stability Analysis;

   Sammanfattning : The power converter is one of the key components in power system applications such as high voltage direct current (HVDC) systems and the grid connection of intermittent sources such as wind and solar power. However, the increased penetration of converter-based generation introduces challenges, such as sub-synchronous interaction between the converter control system and the grid. LÄS MER

3. 2. Mitigating SSCI in a hybrid wind and PV farm utilizing PV-STATCOM : A Swedish case study

   Master-uppsats, Högskolan Dalarna/Institutionen för information och teknik

   Författare :Isabelle Löfgren; [2022]
   Nyckelord :impedance analysis; PV-STATCOM; SSCI; SSO; SSR; sub-synchronous control interaction;

   Sammanfattning : The share of electricity generation in the power system being based on power electronics is increasing, which will impact the system in different ways, such as an increased risk for undesired interactions. An example is doubly fed induction generator (DFIG) based windfarms which have been shown to present negative resistance in (parts of) the sub-synchronous range (i. LÄS MER

4. 3. Utvärdering av faskompenseringsmetoder för ett småskaligt vattenkraftverk : Genomgång av kondensatorbatteri, aktiv och passiv reglering, övermagnetiserad synkronmaskin, SVC och STATCOM på Fröslida kraftverk

   M1-uppsats, KTH/Hälsoinformatik och logistik

   Författare :Fuat Göker; Christoffer Hedberg; [2018]
   Nyckelord :Power factor correction; efficiency; active; passive; total harmonic distortion; budgeting; capacitor bank; synchronous machine; SVC; STATCOM.; Faskompensering; effektivisering; aktiv; passiv; distorsion; kalkyl; kondensatorbatteri; synkronmaskin; SVC; STATCOM.;

   Sammanfattning : Småskalig vattenkraft är en stor användare av reaktiv effekt då de ofta har asynkrongeneratorer. Det gör att det finns ett reellt behov för faskompensering, dels för att minska distorsion i nätet samt för att förbättra deras ekonomiska ställning, då elbolag ofta tar ut en avgift för överskridande användning av reaktiv effekt.

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

   Master-uppsats, KTH/Elkraftteknik

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

   Sammanfattning : 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.

7. 5. Development of EMT Simulation Model to Use RMS Control Model

   Master-uppsats, KTH/Skolan för elektro- och systemteknik (EES)

   Författare :Priya Kalikavunkal; [2016]
   Nyckelord :;

   Sammanfattning : Evolution is continuous and as a result, developments in semiconductors are endless. This led to the Voltage Source Converter (VSC) based High Voltage Direct Current (HVDC) converter termed as HVDC light. HVDC light is quite preferable because of its pros in the technology used as well as the application it is used for. LÄS MER
