    High Voltage static dynamic reactive Power compensation and filter device

    MEC module of power quality integrated optimization device

    MEC module product introduction
    The MEC module for comprehensive optimization of new power power power quality has a fast dynamic reactive power compensation, which can be used to compensate for impact loads by transforming the variable capacitive reactive power into rated reactive power in a very short period of time. There will be no problems such as overfilling or underfilling, and the filtering of the high harmonics of each phase will effectively control the voltage fluctuations and flash changes of the grid, suppress the imbalance of the three-phase(current) of the grid, and dampen the resonance of the grid, which is suitable for various working conditions. It is beyond the reach of traditional reactive compensation equipment.

    Reactive power compensation capacity
    Gradless adjustment from capacity to rated sensibility, good compensation effect
    Graded casting and cutting adjustment, there are cases of overpayment and underpayment, the compensation effect is poor
    Gradless adjustment from capacity to rated sensibility, good compensation effect
    Compensatory capacity
    Module nominal capacity is the rated output capacity of the device, the selection of simple
    The actual output capacity of the module is less than the nominal capacity of the capacitor. It is necessary to use the formula to convert it. The selection type is relatively complex.

    Three-phase imbalance management
    Three-phase AC power through the DC side connection, can deploy power, three-phase imbalance management ability is strong
    No such function
    Three-phase AC power through the DC side connection, can deploy power, three-phase imbalance management ability is strong
    reliability
    Module unit in parallel, backup each other, fault unit does not affect the operation of the entire machine, high reliability
    Self-healing capacitor is easy to resonate with the system after the capacity attenuation, damaging the equipment in the system, and the reliability is poor.
    Two sets of control systems are installed on the same bus. There may be interference and low reliability
    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
    All the parts are open structure, operation is easily affected by dust, failure
    Useful life
    Imported electric electronic components IGBT, no vulnerable parts, design service life greater than 20 years
    The capacity value of self-healing capacitor decays rapidly during use, and the general service life is 2 to 4 years.
