Active Harmonic Filter Application Case: Coal Machine Equipment

Coal machine equipment main load on site:

Welding machine: non-linear load. When the equipment is started, it needs to establish a magnetic field, consume a lot of reactive power, and generate harmonic current in the operation process, causing line loss and equipment loss, thus generating the demand for harmonic and reactive power.

Inverter: non-linear load, the harmonic generated flowing into the power distribution system will cause harm to the power grid, and will also reduce the service life of the equipment, which has a significant impact on the safe and reliable operation of the power distribution system, so there is a demand for harmonic control.

Harmonic control scheme:

According to the accurate analysis of field load, it is recommended to use Active Harmonic Filter AHF and Reactive Power Compensation TSF products for harmonic control and reactive power compensation, effectively governing harmonic current, improving power factor, reducing system loss, increasing transformer load capacity, and reducing zero line current. It solves the problem of harmonic and reactive power for customers.
