VAr Compensator Studies
Advanced reactive power control solutions for enhanced voltage regulation and system stability
What is a Static Var Compensator (SVC)?
A Static Var Compensator (SVC) is a shunt-connected device designed to regulate reactive power by dynamically absorbing or generating vars to maintain or control specific electrical system parameters, typically bus voltage.
TCR
Thyristor-Controlled Reactor
Continuously adjustable reactance using partial conduction of thyristor valves.
TSC
Thyristor-Switched Capacitor
Switches capacitors ON/OFF via thyristor valves, often paired with damping reactors.
TSR
Thyristor-Switched Reactor
Switches reactors ON/OFF using thyristor valves.
Benefits of Static Var Compensators
SVC systems provide critical capabilities for modern power system operation and control
Voltage Control
Steady-state and dynamic voltage regulation, even at points distant from the SVC connection.
System Stability
Enhancing system voltage during normal and disturbed conditions.
Transmission Capacity
Increasing circuit capacity limited by receiving-end voltage or stability constraints.
Voltage Recovery
Restoring bus voltage after faults or load rejection events.
Oscillation Damping
Mitigating oscillations (0.2–2.0 Hz) to improve dynamic stability.
Power Factor Control
Rapid adjustment for power factor, load imbalances, and harmonic filtering.
How We Perform SVC Studies
Our comprehensive approach ensures accurate analysis and optimal SVC performance
Data Collection
Gather relevant information, including single-line diagrams (SLD), SVC specifications, and system-specific data (e.g., load flow, short circuit, transient, harmonic, stability).
