Power Quality Problems In Commercial Complexes A large number of automation equipment in commercial complex automation systems require high-quality power supplies. However, a considerable part of these devices have become disturbance sources that cause harmonic distortion in low-voltage power supply systems due to their nonlinear load characteristics. It will cause pollution of the power distribut...
Background Hongsan Industrial Park is a professional functional zone characterized by rubber industry, and the electric loads are mainly rubber cutters, open mills and internal mixers. The electric power consumption of the motor in the internal mixer system accounts for about 70% of the total electric power consumption in the rubber industry. Because of the high power of the internal mixer an...
Power Quality Problems With the in-depth application of power electronic technology, the automation of the petrochemical industry has been continuously improved, and the nature of the load has also undergone qualitative changes. The increase of nonlinear and impact loads has brought about voltage flicker, three-phase imbalance, and excessive reactive power consumption. , harmonics and a series of ...

Background Jiangyin Huaxin Steel Cable Co., Ltd. produces thick zinc-coated prestressed steel wire, stranded wire and other steel wire, bar steel, steel wire metal products and stainless steel sheet materials. Power Quality Problem In the production process, the harmonic content of the power grid is relatively large, the power quality is poor, and the original reactive power compensation eq...
Current and voltage harmonics are often used interchangeably. At most places, only harmonics is quoted and whether the values pertain to current or voltage is not mentioned. The differentiation can be done on the basis of their origin. What is Total Harmonic Distortion? The current and voltage harmonics in a system are often expressed as Total Harmonic Distortion (THD). The total harmonic d...
In modern industrial processes, the number of nonlinear loads - known to be a major source of current harmonics - is constantly growing. At the same time, the number of reactive-power compensators operating in these networks is growing too. Though the compensators are not the source of harmonic distortions, they may cause high amplifications of harmonics by creating resonance conditions. This can ...
Power Quality Concept IEEE's technical definition: Qualified power quality means that the provided power and grounding system are suitable for the normal operation of sensitive equipment. The concepts of power quality problems raised by modern power systems: Any power problems that cause damage to user equipment or abnormal operation due to voltage, current, and frequency deviations. IEEE51...
