Real-Time Simulation of Static VAR Compensator and Static Synchronous Compensator

International Journal of Recent Technology and Engineering (IJRTE), 2020
In recent years, deregulation, open access, and co-generation in electrical power system are creating transmission voltage sags, swells, forced outages, and frequently followed by black-outs, congestion scenario, and many such problems. Reactive power limit is one of the major causes of voltage instability in the power system, and improving the system ...

Improvements in Bidirectional Power-Flow Balancing and Electric Power Quality of a Microgrid with Unbalanced Distributed Generators and Loads by Using Shunt Compensators

Energies, 2018
Improper connections of unbalanced distributed generators (DGs) and loads in a three-phase microgrid cause unbalanced and bidirectional power flow problems. The unbalanced DGs and loads may also aggravate the electric power quality (EPQ), such as voltage

Reliability model for a Static Var Compensator [PDF]

2017 IEEE Second Ecuador Technical Chapters Meeting (ETCM), 2017
This paper presents a reliability model of a Static Var Compensator (SVC) using an innovative algorithm based on sequential Monte Carlo simulation and Markov chains. The method employs the equivalent circuit of a SVC and takes the failure rate and repair time of each component as input in order to compute the failure rate and repair time of the whole ...

Power analysis of static VAr compensators [PDF]

International Journal of Electrical Power & Energy Systems, 2008
Analysis of three-phase loads usually assume them to be three impedances in a star or triangle connection. This is the reason why obtained results can only be considered valid for passive loads, strictly speaking. Analysis leading to the proposal of some static compensators is usually performed in this way, which induces to believe that this ...
