690v Active Power Filter For Power Factor Correction And Load Balancing

Short Description:

690v Active power filter based on our company many years experience, is a very reliable product. The user can set the parameters so that the active harmonic filter apf can simultaneously filter out harmonics, dynamically compensate reactive power, compensate for three phase unbalance, and compensate for voltage drop, etc.

An active filter system consists of one or several AHF modules and an optional touch screen HMI. Each AHF module is an independent harmonic filtering system, and users can change the configuration of the harmonic filtering system by adding or removing AHF modules.

The AHF is available in three mounting modes: rack mounted, wall mounted, cabinet mounted.

Features

690v active power filter is a new type of electronic device for dynamic filtering of harmonic wave and reactive power compensation. It can conduct real-time filtering and compensation to harmonic wave (both size and frequency are changed) and dynamic reactive power, and is used to overcome disadvantages of traditional harmonic suppression and reactive compensation methods of traditional filters,thus realizing systematic harmonic filtering function and reactive power compensation function. In addition, it is widely applied into power,metallurgy. petroleum, port, chemical and industrial and mining enterprises.

1. Multiple monitoring interfaces to local/remote monitoring system.
2. IGBT and DSP chips are reliable brands.
3. Effectively control the temperature rise of the equipment.
4. Adapt to the harsh natural environment and power grid environment.

5. Three level topology, small size and high efficiency.
6. DSP+FPGA architecture, high speed computing power.
7. ≥20 modules are combined, and any unit can operate independently.
8. Provide customized services for structure, software, hardware and functions.

The 690v active harmonic filter operates on a 3-level neutral point clamped(NPC) topology. As shown in the above, the traditional 2-level topology circuit structure consists of 6 IGBTs( 2 IGBT power devices on each phase pin and current path ), and in the 3-level topology, there are 12 IGBTs( in each phase 4 IGBT power devices on pins and current paths ).

The 3-level topology circuit can generate three voltage levels at the output, including DC bus positive voltage, zero voltage and DC bus negative voltage. Two-level topology circuit can only output positive and negative voltages. At the same time, the three-level topology circuit also ensures higher quality and better harmonic output voltage, thereby reducing output filter requirements and associated costs.
