Description
Magnetically Controlled Shunt Reactors (MCSR)
Magnetically Controlled Shunt Reactors play a critical role in power systems by maintaining
reactive power balance, improving energy quality and increasing operational efficiency.
Thanks to their thyristor-controlled structure, they dynamically regulate reactive power
by adjusting the firing angle between 180° and 90°.
By changing the direct current (DC) flowing through the winding, the magnetic core saturation
level is controlled, allowing precise adjustment of the inductance value.
Main Technical Features and Advantages of MCSR Systems
- Operates as an adjustable inductance element within the power system.
- The adjustment range is between 5% and 100% of reactor power.
- Improves power factor.
- Reduces transmission losses.
- Increases line capacity.
- Supports voltage stability of the power system with continuously adjustable capacity.
- Provides high operational reliability.
- Generates low harmonic content.
- Plays a critical role in the safe and stable operation of electrical networks.
- Supports reliable operation of power plant generators.
Applications and Technical Advantages
MCSR systems are widely used in steel and metallurgical plants, petrochemical industries,
coal mining facilities, shipyard and crane systems, wind power plants and railway
electrification infrastructures.
These applications protect power quality, reduce voltage fluctuations and improve energy
efficiency.
From technical, economic and maintenance perspectives, Magnetically Controlled Shunt
Reactors provide a more effective and reliable alternative compared with thyristor-controlled
reactors, capacitor banks forming SVC systems and synchronous condensers.
