The petrochemical industry has a high degree of automation, and the increase of nonlinear load has brought serious harmonic problems, affecting the safe operation of the power grid and reducing the production capacity. There are a large number of rapidly changing impact loads in production, and the access of a large number of nonlinear loads inevitably leads to many power problems: low power factor, excessive reactive power consumption, harmonic interference, etc.

Solve the harmonic interference

caused by high-power frequency

conversion equipment,thyristor

rectifier equipment, etc.
