Standard harmonic compensation module unit

  Bdkj-lc portable filter reactive power compensation unit 1
Overview of portable filter reactive power compensation unit
Bdkj-lc portable filter reactive power compensation unit is applicable to occasions that need to suppress harmonic compensation reactive power, such as medium and high frequency heating, DC motor drive, frequency converter motor drive, rectifier and inverter power supply, etc
the unit device adopts comprehensive intelligent control to accurately calculate the switching filter compensation power unit by collecting the operating parameters of the load, so as to realize accurate and rapid compensation of reactive power, effectively suppress harmonics and achieve the best compensation effect
The portable filter reactive power compensation unit has the advantages of convenient use, convenient installation and small floor area
It is suitable for various occasions
Especially in the transformation of the traditional reactive power compensation cabinet, it can better reflect its convenience and practicability
The portable filter reactive power compensation unit is divided into control unit A single control unit can control multiple groups of power units
For example, the filter compensation capacity of 800 transformer is considered as about 50% of the capacity (i
e
about 400kvar), and the portable filter reactive power compensation unit can select 6 60KVAR power filter compensation units and control unit One 20kvar power filter compensation unit with a total capacity of 380kvar

Function of portable filter reactive power compensation unit
Intelligent acquisition and control output can quickly compensate the reactive power required by the load, and the compensation is in place in one step

20kvar automatically fine compensates the load reactive power, making the compensation accuracy higher

Improve line power factor, improve line voltage quality and reduce line loss

Suppress high-order harmonics of the system and prevent harmonic oscillation amplification of the system

Reduce the reactive current of main transformer and increase the output capacity

It is suitable for reactive power compensation of various bus changes

Characteristics of portable filter reactive power compensation unit
Independent anti-interference design ensures stable operation in various harsh electromagnetic environments

Advanced intelligent logic reactive power control technology is adopted to achieve the best reactive power compensation control effect

Multiple groups of power units with different capacities are matched and switched to balance the input branches and prolong the service life of power units

According to the multi group operation mode of the load, the compensation strategy is automatically adjusted to make the bus load balance obtain reactive power compensation and achieve the best compensation effect

It has complete protection functions: overvoltage, undervoltage, overcurrent, overtemperature, harmonic crossing, etc

It has automatic control, manual control and remote control

It has complete heat dissipation and temperature control system and complete alarm and indication system

The portable filter reactive power compensation unit adopts the partial harmonic design of filter reactor series filter capacitor to suppress the system harmonic and compensate the reactive power stably and reliably

Simple installation and operation, reliable operation and easy maintenance
