Understanding FACTS Devices: STATCOM, SVC, and UPFC Explained
A clear explanation of FACTS devices — STATCOM, SVC, and UPFC — covering how they work and how to approach them as student simulation projects. By Expert Agencies Team | Electrical & Electronics Engineering Project Support Flexible AC Transmission Systems (FACTS) devices are a favorite topic for power systems projects because they sit at the intersection of power electronics and transmission engineering. Here's a plain-language breakdown of the three most commonly studied devices. Static VAR Compensator (SVC) An SVC is a shunt-connected device that uses thyristor-controlled reactors and capacitors to regulate reactive power at a bus. It's relatively simple to model and is often the first FACTS device students simulate, since it demonstrates voltage support without complex switching control. Static Synchronous Compensator (STATCOM) STATCOM performs a similar function to SVC — reactive power compensation — but uses a voltage-source converter instead of thyristor-swit...
