    High Voltage static dynamic reactive Power compensation and filter device

    Active Filter APF Module

    APF module product introduction
    New Power Active Power Filter APF has the characteristics of fast response speed, strong filtering ability, flexible installation, and convenient expansion, which can meet the needs of different users. The new-power APF adopts a modular design, which improves the reliability of the entire machine. It has a fast adjustment speed and a wide range of operation. After adopting multi-gravity and multi-electric equal PWM technology, the carrier frequency harmonic content of the compensation point is greatly reduced. Each module of APF can individually or simultaneously compensate for reactive power and harmonics.

    Comparison of APF Module and Channel Filter Technology

    New Power APF Module
    Passive LC channel filter module
    Filtering capabilities
    There is a strong filtering effect on harmonics within 50 times, and it can filter out the specified multiple harmonics, and it will not amplify other harmonics in the system.
    Only one harmonic can be filtered, and the filtering ability is greatly affected by the impedance of the system, and the harmonic below the cut-off frequency is amplified.
    Whole machine reliability
    Unit in parallel, mutual backup, fault unit does not affect the operation of the entire machine, high reliability
    With the attenuation of the capacitance of the power, the resonance point of the LC circuit will be offset, there is a risk of resonance, and the reliability is low.
    Environmental adaptation
    Power module seal, independent duct, no need for regular circuit maintenance, significantly reduce dust caused failure
    All the parts are open structure, operation is easily affected by dust, failure
    Departure and maintenance
    After the fault, the fault point can be recorded by the controller, and the replacement module can be run online. There is no need to stop the service and the obstacle removal time is short(within 1 hour).
    After the fault, it needs to be shut down and repaired. It can not be operated and the obstacle removal time is longer.
    Installation Size
    Modular design, high power density, volume 1/3 -1 / 2
    The filter reactor is generally designed as an air resistance and has a large installation space(usually a cabinet with a width of 1.2 meters).
    Minimum no-fault time
    Imported electric electronic components IGBT, no vulnerable parts, its service life is greater than20years
    The capacitance of the power will decay with time, and the service life is 2 to 4 years.
