SVC-solved problems

Electric arc furnace

When the electric arc furnace connects to grid as one nonlinear and ruleless load, it will trigger a series of harmful effects, which mainly includes:
1 severe 3-phase unbalance of grid, and negative sequence current.
2 higher harmonics, the coexistence of 2f, 4f, the even harmonics and 3f, 5f, 7f, the odd harmonics, which will be perplexed the voltage distortion.
3 severe voltage flicker.

4 Low PF.
The only way to completely solve above mentioned problems is that user must provide the SVC with rapid response speed for electric arc furnace. Since the response time of SVC is less than 10ms, it can completely meet the strict technical requirements, swiftly provide reactive current for EAF, stabilize system voltage, increase output of metallurgical active power and enhance production efficiency, as well as minimize the flicker effect. The phase splitting compensation capability of SVC can eliminate 3-phase unbalance caused by EAF. Harmonics filtering device can remove harmful higher harmonics, improve power quality and increase PF by transferring capacitive reactive power to system.
