Shunt Reactors
Shunt Reactors are designed for reactive power compensation and voltage control in transmission systems.
Shunt reactors are applied in high-voltage networks to absorb reactive power, control overvoltages, and stabilize voltage profiles along transmission lines.
Each unit is engineered according to system electrical parameters, short-circuit levels, load conditions, and applicable technical standards.
Role in System Stability
Shunt reactors are connected in parallel to transmission lines in order to:
- Absorb reactive power under low-load conditions
- Reduce overvoltages
- Improve voltage profile along long transmission corridors
- Support stability in interconnected and large-scale networks
Their application is essential in extended transmission systems or grids with high operational variability.
Applications
- Transmission substations
- Long-distance transmission lines
- Regional interconnections
- Networks with high renewable energy integration
Operating Principle
A shunt reactor operates by absorbing reactive power when connected in parallel to the grid, contributing to the balance between active and reactive power and maintaining voltage within defined system limits.
