SVC
Static VAr
Compensation Systems
Static VAr Compensation (SVC) is onae of the reactive power compensation and voltage regulation systems which consist of static, or semiconductors, switching elements. Thyristor Controlled Reactor (TCR) and Thyristor Switched Capacitor (TSC) are the most common SVC systems.
Primary Benefits
- Power factor correction
- Voltage regulation improvement
- Flicker mitigation
- Load Balancing
- Power oscillation damping
- Increases transfer capability of transmission systems
- Voltage ride through support
Application Areas
- Transmission and Distribution Systems
- Metal Industry
- Railway Transmission Systems
- Mining Industry
- Cement Industry
- Oil & Gas Industry
- Grid code compliance applications of solar and wind energy systems
Benefits of SVC
- Reduction in active energy losses by improving
reactive power flow and filtering harmonics - Improvement in system stability with load balancing and flicker reduction
- Better utilization of transmission and
distribution systems - Increasing the quality of supply
- Reduction of production cost in iron and steel industry
Fundamentals

How it works?
- Thyristor Controlled Reactor (TCR)
- Controllable component of SVC
- Provides inductive reactive power
- Consisting air core reactor and with a bidirectional anti parallel thyristor stack called as thyristor valve
- Act as a variable reactor
- Reactive power output can be controlled from 0 – Qmax continuously
- Fast response time – 10 ms
