Advantages of 10kv power quality combined compensator

It can be known from the description of the principle of 10kV power quality comprehensive compensator that the 10kV power quality integrated compensator can automatically adjust the magnitude and nature (capacitive or inductive) of the reactive power output according to the load characteristics and working conditions. Therefore, in essence, the 10kV power quality integrated compensator can be equivalent to a capacitor or reactor whose size can be continuously adjusted.

The 10kV power quality comprehensive compensator is the most advanced reactive power compensation technology. Its compensation device based on voltage source converter realizes the qualitative leap of reactive power compensation. Instead of using large-capacity capacitors and inductive devices, it uses a high-frequency switch of high-power power electronics to achieve a non-functional conversion. Technically speaking, the 10kV power quality integrated compensator has the following advantages over the traditional reactive power compensation device:

(1) faster response time

10kV power quality comprehensive compensator response time: <5ms.

Traditional dynamic compensation device response time: ≥ 50ms.

The 10kV power quality integrated compensator can convert the rated capacitive reactive power to the rated inductive reactive power in a very short time. This unparalleled response speed is fully capable of compensating for the impact load.

(2) Stronger ability to suppress voltage flicker

The traditional motion compensation can suppress the voltage flicker up to 2:1, and the 10kV power quality integrated compensator can suppress the voltage flicker by 5:1 or even higher. In addition, since the 10kV power quality integrated compensator has a very fast response speed, increasing the capacity of the device can continue to increase the ability to suppress voltage flicker.

(3) wider operating range

The 10kV power quality integrated compensator can operate in the range of rated inductive to rated capacitance, so it is much wider than other types of dynamic compensation. More importantly, the 10kV power quality integrated compensator can also output reactive current close to the rated operating condition when the system voltage becomes low. Other types of dynamic compensation rely on capacitors to provide capacitive reactive power. The reactive current output is proportional to the grid voltage. The lower the grid voltage, the lower the reactive current output, so the compensation capacity of the grid is also changed accordingly. weak. This is an essential shortcoming of other types of dynamic compensation techniques.

(4) Diversification of compensation functions

The same set of 10kV power quality integrated compensator device can realize different compensation functions:

2 separately compensated load reactive

2 Separate compensation of load harmonics

2 separately compensate for load imbalance

2 Compensating for load reactive, harmonic and unbalanced

Therefore, the 10kV power quality integrated compensator has a powerful compensation function.

 

(5) Active filtering function

The 10kV power quality comprehensive compensator adopts PWM technology, which not only generates very low harmonic content, but also compensates the harmonics and reactive power of the load, realizes the function of active filtering, and truly multi-functionalizes.

(6) Small footprint

Since large-capacity capacitors and reactors are not required for energy storage components, the footprint of a 10kV power quality integrated compensator is usually only 50% or less of other types of dynamic compensation of the same capacity. Therefore, in some mines and mines, the 10kV power quality comprehensive compensator has great advantages.
