THEORY OF OPERATION:

Arteche Type AHF Active Harmonic Filters utilize the latest IGBT power electronics technology to achieve dynamic cancellation of harmonics caused by three phase non-linear loads. The system will monitor the load current and dynamically correct each individual harmonic from the 3rd to the 51st. Through the injection of an inverse rela-tionship compensating current into the load, harmon-ics are significantly reduced and the sine wave is restored. Because our filter uses state of the art, fast switching PWM IGBT technology, it is capable of responding to rapid load fluctuations. Type AHF active filters will enable power systems or individual non-linear loads to meet the harmonic distortion limits of IEEE-519 for Total Demand Distortion (TDD) as specified in table 10.3 of the IEEE 519 Standard.

IEEE-STANDARD 519:

IEEE Standard 519 defines recommended limits for both harmonic current and voltage distortion. TDD represents Total Demand Distortion and is evaluated by analyzing the harmonic current distortion in % of maximum demand load current (15 or 30 minute demand).

Meeting IEEE 519 with Active Filters

BENEFITS TO POWER SYSTEM

AND POWER GENERATING EQUIPMENT: Because harmonic current flows through upstream system conductors, transformers and other electrical equipment, harmonics can cause measurable power system losses on the basis of I2R. More harmonics means higher true rms amperes and thus higher power losses. Considering that harmonics are flowing at higher frequencies (5th = 300hz, 7th = 420hz, etc), due to skin effect, conductor resistance is higher for the harmonic frequencies than for 60hz which further increases system losses. The impact of harmonic currents, are also seen in transformers and motors because they increase iron losses and temperature rise which has an impact on equipment life expectancy. For motors and transformers, life expectancy is cut in half for each additional 10 degrees Celsius of higher operating temperature. Installing an active harmonic filter reduces the electrical burden (KVA) for transformers, generators and distributed generation power sources. They reduce both the rms and peak current demands for this equipment. By reducing wasteful harmonics, it may be possible to release sufficient capacity in existing electrical power sources to enable the existing infrastructure to accept additional new loads.

The multifunctional LCD graphic display also serves as a controller, harmonics analyzer and offers both system management and networking capability. It has an eight function keypad that facilitates the operation, programming and diagnostics of the filter. Information for up to the 31st harmonic (most predominant range) is displayed including

waveform data. The controller allows for global (all harmonic orders) or selectable (specific harmonic orders) and settable VAR correction for maximum flexibility.

Inherent in our Type AHF filters is the capability to improve power factor by supplying VARs needed for reactive compensation. When high levels of power factor correction are also necessary, Arteche can also offer passive or active solutions as well as hybrid products that consist of both passive and active elements.

Type - AHF Active Harmonic Filter Selection

Product Selection 

Selection Make the proper selection of active harmonic filter by first determining the magnitude (in rms amperes) of harmonic current flowing on the phase conductors. From the proper line voltage rated filters, select the one with an equal or next greater current rating. For the best overall perform-ance and life expectancy, select AHF with approximately 25% more capacity than current maximum requirements.

[Example: 480V power system, harmonic current = 82Arms. Select AHF-0100-480-60-N1.] The residual harmonic current distortion will be <5% THD-i. DC-drives must have a 3-phase AC reactor (3% minimum) or a drive isolation transformer inserted between the ARTECHE AHF connection point and the drive AC input.

AC-drives (VFDs) must have a 3-phase AC reactor (3% minimum) or drive isolation transformer with electro-static shielding inserted between the connection point and the drive AC-input, unless the drive is a PWM type drive with a diode rectifier and has a DC-bus reactor. In that case the AHF may be connected directly to the drive AC input terminals. NOTE: As a general principle, we recommend a 25% higher rating than the rms harmonic current (Ih) to be compensated. For example, if the known load harmonic current amplitude is 40 Amps, the appropriate rating of the AHF should be 50 Amps. In the event the real values of the Ih are higher than the estimated one, or the Ih increases due to additional loads, there is no overload risk on the existing AHF that has been selected.

Reactive Power: Reactive Power Capacity (kVAR Leading) In addition to canceling harmonics, our active filters have the capability to improve power factor by providing capacitive kVARs and leading (PF) current which can be used to cancel inductive kVARs and amperes (A) up to their rating as illustrated in the following table.

Type AHF Active Harmonic Filters will help to improve displacement power factor in addition to minimizing harmonics. The charts below indicate the available reactive power (or current) that can be provided by the Active Harmonic Filter in addition to the harmonic compensating current. Reactive compensation, per charts below, is always available while AHF is operating.
