Power quality

  New technology - Baoying Long active role in filtering the

 

   With power electronics technology development and wide application of power system increasingly non-linear loads such as rectifiers, converters, UPS, household appliances and computers. These non-linear loads and generate harmonic currents injected into the grid, the voltage of the waveform distortion of the grid, the resulting grid harmonic "pollution." In addition, the impact of volatility loads such as electric arc furnaces, welding equipment, etc., not only in the operation will generate a lot of high harmonics, voltage fluctuations and will, flicker, phase imbalance increasingly serious safety hazard grid operation. At the same time, production, process automation and intelligent living and a variety of sophisticated precision equipment, power quality also put forward higher requirements, so the power system harmonic control has become an urgent problem.
