COMSYS ADF P300 Active Harmonic Filter

COMSYS ADF P300 Active Harmonic Filter

COMSYS ADF P300 is the world's best and versatile dynamic active harmonic filter (AHF) with industry leading performance with fully customizable harmonic compensation, dynamic VAR reactive power compensation, load balancing, and flicker compensation. Compatible with low and medium voltage, typical applications include utility, data centers, small to medium manufacturing companies, industrial loads, fluorescent lamps, HVAC, EV charging stations, variable speed drive (VSD) systems, UPS systems, medical equipment, offices and commercial buildings, fan and pump applications, and more. The P300 is encased in a compact cabinet, and its modularity means that up to 15 units can operate in parallel for higher power output. The COMSYS ADF series is the only solution in the world with sensorless control, meaning no CTs (current transformers) are required. The web user interface (WUI) allows remote monitoring and control. Modbus TCP enables flexible functionality with integration to overlying control such as a PLC or SCADA systems.

What to expect with ADF?

ADF Operating Principle - How it Works.

An ADF unit is basically a very advanced computer-controlled current generator with the ability to instantly produce any shape or form of compensation current.

A simplified diagram of the operating principle is shown in the figure. Each ADF unit is connected in parallel, in shunt, with the load that requires compensation.

  • The power flows of electrical currents between the load and the network are measured and analyzed [1] to determine if disturbances such as reactive displacement and /or harmonics are present.
  • If found, the ADF unit injects compensation current [2] that are the exact opposite of, for example, the harmonics and/or reactive displacement.
  • This is done in order to cancel out the load behavior [3].

NO CTs Required. The ONLY solution with Sensorless Control

When you need a retrofit solution or you have a complicated set-up, it can be very difficult to add the CTs (current transformers). But with Sensorless Control, we can compensate without it — so you can eliminate the CTs altogether. This gives you more flexibility when it comes to where and how to install the ADF unit and reduces the overall hassle of installation and compensation. In addition to this, you are also able to isolate sub-grids and compensate background distortion, which further improves the flexibility and adaptability of the ADF platform.

Sensorless Control is now available on all ADF products.

Remote Monitoring and Control of ADFs

The WUI (web user interface) is a web application requiring no additional software installation. It offers a convenient, easy-to-use service to enable you to monitor your ADF modules from any device – anywhere, anytime. Additionally, the WUI can be integrated into a larger system (i.e. with multiple generators, many loads, etc.), which you can then choose to run on a certain schedule or operation mode. And if your operation uses a PLC, the PLC can read out critical data from the ADF module automatically.
