FGI has served the coal mining industry for more than 30 years, providing five series of products and services of "less electricity, good use of electricity, renewable electricity, storage electricity, explosion-proof electricity", among which the technical level of long-distance power supply comprehensive treatment device has reached the leading level in China, solving the problem of long-distance power supply in the mining industry in fully mechanized mining, driving face and underground high and low voltage transmission line long-distance power supply system.

1.Industry difficulties

The traditional method has some problems, such as mechanical regulation, poor regulation characteristic, overcompensating reactive power, low power factor, overvoltage, closing inrush current, high harmonic amplification, capacitor explosion and so on.

2.Solution

Static Var Generator (SVG) centralized compensation solution

3.Program advantage

High voltage explosion-proof SVG covers 6kV, 10kV, complete certification specifications, maximum power 6Mvar;

High voltage explosion-proof SVG is configured in the underground high voltage power supply line, which can centrally compensate the load of the whole working face;

High voltage explosion-proof SVG has high integration and the smallest volume in the industry;

High voltage explosion-proof SVG improves power factor, filters out harmonics, and improves the long distance capability of the power supply line.

4.application case

Power factor increased to 0.99;

10kV bus power supply distance 10km;

The power grid bus voltage is increased by 500V;

Compensate the harmonics of the power grid and improve the quality of power supply;

Reduce reactive power loss to achieve energy saving and consumption reduction.
