Short Description:
The KRMSVC type high-voltage dynamic reactive power compensation device is an automatic control device for reactive power compensation and voltage optimization, integrating MCR, capacitor group switching, and on-load tap-changing transformer functions. The MCR is a 'magnetic valve' type controllable saturated reactor, which adjusts the saturation level of the core by changing the excitation through DC control current, thereby achieving smooth regulation of reactive power output. With capacitor group switching, it can achieve bidirectional dynamic continuous adjustment of reactive power. In addition, the MCR capacity only needs to be close to that of a single large-capacity capacitor group to meet reasonable compensation requirements, reducing equipment costs while significantly lowering operating losses.
