Power Background:

1), high-voltage 35KV side traction rectifier inverter device generated high-order harmonics, the dominant harmonic is 11 times, 13 times, 23 times 25 times;

2) The natural power factor of the low-voltage side is low, and the reactive power and harmonic wave are large when the load is working at night;

3), high-voltage side of the natural power factor is higher, due to the long power supply line, at night when the load is low reactive reverse phenomenon;

Recommended scheme:

1) In terms of harmonics, APF active filter is directly connected to the bus below 35KV through the step-up transformer to filter out high harmonics.

2) In reactive power compensation, HDVG is used to connect the bus below 35KV through 10KV step-up transformer to adjust the power factor in both directions to prevent reactive power reverse transmission.

Customer Benefits:

Reduce the harmonic content to ensure the safe and stable operation of the power supply system in the metallurgical industry;

Safety improvement of power factor to avoid fines caused by reactive power reverse;

Save energy and reduce consumption, reduce harmonic content, and avoid equipment malfunction.
