With the wide application and development of power electric technologies, there are more and more nonlinear loads in the power system, such as rectifiers, frequency converter, UPS, household applications, LED lights, computer and other equipment. When a sine wave voltage is applied to the nonlinear loads, the current becomes a non-sine wave. Non sinusoidal current, which generates voltage drop on the power grid, can also cause the voltage waveform to become non sinusoidal. The components with the same frequency as the power frequency contained in non-sine waves are called fundamental waves, and the components with a frequency greater than the fundamental waves are called harmonics. The nonlinear loads will generate harmonics currents and inject them into the power grid, causing distortion of the voltage waveform, thereby causing harmonic “pollution” of the power grid.
With the increasing widespread applications of power electric devices all over the world, the proportion of AC/DC converter equipment and switching loads is increasing, and harmonic pollution in the power grid is becoming more and more serious. At the same time, the power factor of most power electric devices is very low, which brings extra burden to the grid. In addition, the negative sequence current generated by three-phase asymmetric load also poses a series hazards to the power system and users, and has a significant impact on power supply quality. The automation and intelligence of the product process, as well as varies complex precision equipment, have put forward higher requirements for power quality. The harmonics have seriously affected the system safety and power supply quality, so its control has become an urgent problem to be solved in the power system.
1. Relying on the advanced intelligent monitoring technology, it has the features of faster, smaller, higher performance, simper and faster improvement of power quality.
2. Quick response: the response time of AcFee APF is less than 300us, making the harmonic eliminated before causing harm
3. Highly integrated: The 25A filter has a compact design and is easy to install. In addition, the 500A filter also minimizes the size while ensuring excellent performance.
4. Easy to maintenance: The AcFee APF benefits from its excellent design, the control unit modularization greatly shortens the repair and maintenance time.
5. Multiple choises: AcFee series have products with various specifications and capacities ranging from 50A-900A.
6. Adaptability: AcFee APF can compensate for self-interference and automatically change network topology.
