Active Harmonic Filter

Transcription

1 Reactive Power and Harmonic Compensation Active Harmonic Filter The new StacoSine Plus active harmonic filter is available in 100, 150, 200 and 300 amp assemblies. Modules can be paralleled for a maximum capacity of 1200 amps of harmonic mitigation. When multiple units are paralleled only one controller in one of the modules is needed to assure proper harmonic mitigation. This controller has a touch screen that allows for easy onsite programming. Besides correcting up to the 51st harmonic, the unit can compensate for both lagging and leading reactive power, and can be programmed from 0.7 lagging to 0.7 leading power factor. Highlights Reduces operation and maintenance costs Variable power factor and harmonic current control gives the user more flexibility to control his power system by allowing power factor improvement without adding a capacitor bank Filters up to the 51 st harmonic so all unwanted harmonic levels are reduced to allow for compliance with the IEEE 519 Standard No need for complex site analysis means simpler application and installation assuring virtually no downtime 480 volt, 100 to 300 amp assemblies are available with paralleling capability up to 1200 amps to correct at larger facilities 7 LCD touch screen allows for easier operator interface One touch screen can control up to 8 modules (up to 1200 amps) in parallel allowing for more precise and predictable harmonic mitigation Units are UL and cul Listed Roll back feature assures that the unit will continue to operate and not overheat in a high ambient temperature environment CTs can be installed on either the source or load side of the active harmonic filter allowing for a more flexible installation Your Tailored Power Solutions Provider TM

2 Harmonic Problems With the increased presence of electronics on power distribution systems, disruptive anomalies are created and harmonics can become a problem. These problems are usually manifested as transformer overheating, motor and generator burnout, neutral heating, electronic control malfunctioning, breaker tripping and capacitor failures. Major contributors to Harmonics Fluorescent Lamps Computers and Peripherals Welding Machines Uninterruptible Power Supplies (UPS) AC/DC Variable Speed Drives Frequency Converters DC Power Systems/Chargers The StacoSine Plus Active Harmonic Filter Active harmonic filters use a DSP control system to monitor the nonlinear load and dynamically correct every harmonic order from the 2nd to the 51st. By injecting a compensating current into the load, the sine wave is restored, attenuating harmonic levels at the point of installation. StacoSine Plus meets or exceeds Total Demand Distortion (TDD) limits specified in table 10.3 of the IEEE 519 Standards. The filter can accept a signal from a CT secondary of 1 amp (standard) or 5 amps with the optional kit that will convert the signal from 5 amps to 1 amp. The StacoSine Plus high speed processor cancels high frequency output current, while it ultimately determines the precise value of injected load current. StacoSine Plus IGBT based platform has been designed to operate at levels that continuously adapt to rapid load fluctuations. With its efficient operation and small physical size, it is ideal for a wide variety of industrial and commercial environments. Typical Applications for Active Harmonic Filters Water and waste water treatment facilities Textile and paper mills Steel mills and facilities with induction furnaces Pharmaceutical facilities Petrochemical plants Data Centers, servers, printers, and other IT equipment Hospitals and medical facilities Solar and wind farms Material handling facilities A Real Solution The StacoSine Plus behaves like a harmonics current generator. It measures the harmonics generated from a nonlinear load and cancels the harmonics with a newly generated, opposite phase shifted harmonic current of the same amplitude (AC/DC/AC). This allows it to: Eliminate all harmonic currents from nonlinear loads Compensate reactive power factor of lagging or leading loads Act as a damping resistor to prevent harmonic resonance Staco Energy Products Co.

3 Why StacoSine Plus is A Better Choice With other harmonic mitigation solutions, expensive and time-consuming site data collection, power quality surveys and computer generated studies are usually needed. Most harmonic filters are designed to accommodate just one or a few harmonic orders. The StacoSine Plus corrects a full range of harmonic orders, and will not create a resonance condition with other existing equipment, so only minimal up-front analysis is required. The StacoSine Plus can be easily and conveniently added in parallel with other active filters, to accommodate future facility expansions or equipment additions. Virtually no time is lost for installation, supporting the important uptime operation of your facility. The rating (size) of the StacoSine Plus is based on nonlinear load requirements (corrective current), not both linear and nonlinear current like traditional filter equipment. That means that you can install a StacoSine Plus system at a reduced ampere rating, which will lower initial capital costs. While injecting current into the system to mitigate harmonics, the Staco Sine Plus also has the capability to compensate for both leading and lagging power factor. The power factor correction can be programmed to correct from 0.7 lagging to 0.7 leading. It can also be programmed for a fixed amount of kvar. The user friendly 7 color touch screen display allows for easy operation and maintenance programming of the active filter. This display can control and show the status of the main active filter and up to seven additional active filters connected in parallel with it. This allows for up to 1200 amps of harmonic current to be injected into the power system to mitigate harmonics. Each filter can be controlled from just one location saving valuable maintenance time. Up to 300 events are recorded and logged for each connected filter. To help save energy, the StacoSine Plus can be programmed to shut down when a certain minimum load current is reached and to be energized when that level is exceeded. Optional monitoring software is available to allow the StacoSine Plus to communicate remotely using USB, RS-485 or Ethernet (TCP/IP) interface. The StacoSine Plus can be set to accept either load side or source side CT signals. This is particularly useful in very tight installations or if the source side connection is at the transformer.
