1- Introduce:
SVC through the dynamic adjustment of reactive power can cause failure due to rapid suppression of transient voltage fluctuations and improve voltage stability and power transmission level; inhibition caused by the impact of load bus voltage fluctuations and improve power factor, reducing the non-linear loads interference caused by harmonics, so that three-phase load balancing, and improve power quality and enhance the user's production efficiency, improve product quality and reduce power consumption. The device is widely used in transmission networks, metallurgy, mining, railway electrification, wind power and other fields.
2- SVC Normal application functions:
- Stable voltage
- Reduce harmonic
- Reduce flicker and reduce their own and neighboring users
- Protection device to reduce the failure rate
- Load balance to reduce the negative sequence
3- Applications in the electric arc furnace
- Reduce the harmonic distortion
- To improve power factor, no power factor penalty
- Stable voltage, the power to raise refining (refining power to increase 5-10%)
- Inhibit voltage fluctuation and flicker
- Smelting reduction of time and increase productivity
- Lower electrode wear and tear (2-3% savings, kg / ton of steel)
- Energy saving (save 2-3%, kWh / ton of steel)
- Stable arc, furnace lining to reduce wear and tear
