Product Description

Automatically alter the output reactive power’s size and type (capacitive or inductive) based on the parameters of the load and the environment. In principle, the 10kV power quality compensator can be compared to a continuously adjustable capacitor or reactor of the same size.

The reactive power compensation approach has achieved a qualitative leap. The transformation of reactive energy is now accomplished through high frequency switching of the huge power electronic devices rather than large capacity capacitance and inductance components. Technically speaking, the 10kV power quality comprehensive compensator is superior to the conventional reactive power compensation device in the following ways:

Advantages of 10kV power quality comprehensive compensator

Better and faster response time

  1. Response time of the comprehensive 10kV power quality compensator is 5ms. The typical dynamic compensating device has a response time of at least 50ms. The 10kV power quality comprehensive compensator can switch from rated capacitive reactive power to rated inductive reactive power in a very short amount of time. The unmatched response time completely makes up for the impact load.

Better suppression of voltage flicker

  1. Traditional dynamic compensation for voltage flicker suppression can be as high as 2:1, however the 10kV power quality complete compensator can be as high as 5:1. Additionally, by increasing the device’s capacity, the ability to suppress voltage flicker can continue to be improved thanks to the quick response of the 10kV power quality comprehensive compensator.
  2. The 10kV power quality comprehensive compensator has a wider operating range than conventional dynamic compensation, operating within the rated inductive to rated capacitive range. More significantly, the 10kV power quality compensator can output when the system voltage is low. Near the rated state, reactive power current. While other forms of dynamic compensation are all provided by capacitors in the form of capacitive reactive power, the output reactive current is inversely proportional to the grid voltage. As the grid voltage decreases, the output reactive current decreases as well, making it harder to compensate the power grid. The primary flaw in other dynamic compensating technology is this.
  3. Diversification of compensation functions is possible using the same set of 10kV power quality comprehensive compensators.
    • Reactive load must be separately compensated
    • Independently correct load harmonic
    • Independently correct load imbalance
    • Equalize the load’s harmonics, reactive power, and imbalance.
    • The 10kV power quality compensator hence has an effective compensatory function.
  4.  Active filter functionality; PWM technology is used in the 10kV power quality compensator. It can adjust for the load’s harmonics and active power in order to perform the active filter’s function, fully realising the multi-function. It not only produces very low harmonics on its own.
  5. Small floor area; The floor area of the 10kV power quality compensator is typically only covered by about 50% of that of other dynamic compensation in the same capacity, even smaller than the 10kV SVG volume, due to the absence of large capacity capacitors and reactors as energy storage components. Therefore, the 10kV power quality comprehensive compensator has many benefits in the renovation of the railway’s 10kV substation.

Protection Function

  1. The device’s over-current protection
  2. Power grid overvoltage protection
  3. Grid protection from undervoltage
  4. DC bus overvoltage protection
  5. The unit’s over-temperature protection
  6. The device’s short-circuit protection.
  7. protection of the unit against communications exceptions
  8. Atypical fiber transmission protection (number 

The gadget has an alarm, a shutdown feature, as well as other appropriate countermeasures and timely upload, so any circuit faults won’t affect the better system. In order to prevent mishaps, the entire set of equipment is capable of automatic detection, remote manual switching, and short distance manual switching. Automatic detection and control occur without human intervention.

After the detecting system has determined that there are no external defects, such as over-voltage and under-voltage protection, the device will automatically turn on.
