MCR
Magnetically
Controlled Reactor
High-quality, specific and cost-effective solutions
for reactive power compensation and harmonic
problems of conventional loads.
Primary Benefits
- Power factor correction
- Voltage regulation improvement
- Increases transfer capability of transmission systems
- Decreasing network losses
Application Areas
- Transmission and Distribution Systems
- Mining Industry
- Cement Industry
- Railway Transmission Systems
MCR Features
- A type of controllable saturated reactor used for shunt compensation
- Can be connected directly to HV levels without step-up transformer
- Used with fixed capacitor/harmonic filter banks to control reactive power flow
- Same functionality with SVCs
- Compared to TCR:
- Lower cost
- Lower harmonic distortion, <3%
- Reduced installation footprint
- Easier maintenance
MCR How it works?
- Structure
- A steel magnetic core with the main and
control windings - Main winding is connected to HV grid
- The control winding is fed by power electronically controlled rectifier.
- Controlled rectifier provides a variable dc superposed magnetization current to control inductive susceptance of reactor.
