APF improve power factor up to 0.99 UL CE CSA
What is APF?
Active Harmonic Filter (APF/STATCOM) is a new active electronic harmonic filtering device to reduce voltage harmonic and current harmonic, improve power factor and improve power quality.
• Chemical industry
• Coal mine industry
• Electroplating industry
• Foundry industry
• Forging industry
• Medical industry
• Machinery production
• Commercial building
• Oil drilling
• Papermaking industry
• Plastics industry
• Textile industry
•Dynamic compensation, doesn't depend on system impedance and not easy to happen resonance.
•Compensate harmonic and reactive power at the same time.
• Adjust reactive power value continuously, not affected by grid frequency
The other key features of APF are as follows:
l Design of cabinet integration and modularization
l Internal structure applies 3H Bridge design and boasts better stable operation.
l Dynamic response in time: response time＜100μs and complete response time＜10ms.
l Overall efficiency: ≥97% (rated power)
l Low noise: ≤65dB
l Harmonic filtration ratio: ≥95%
l Flexible offset way: amplitude settings can be performed for harmonic offset at each level selected
l Easy to operate with user-friendly interface.
l Protection functions for over-current, overvoltage and overheat etc.
l Auto current limitation, as the output current ≥ the rated, the current will be limited.
Working Principle of APF
Through the external current transformer CT, theAPF detect realtime grid current or load current the controller extract the fundamental current harmonic current through the fast Fourier transform,get active power, reactive power and negative sequence data by the DQ rotation coordinates, generate compensating current into power grid with same value opposite direction as compensating target (harmonic, reactive power, 3 phase imbalance) through IGBT power converter, realize power quality improvement.
Three-phase three-line and three-phase four-line
Rated Working Frequency
1. Compensate harmonics, specified harmonic select
2. Compensate harmonic and reactive power, some types available
3-50 harmonics(specified harmonic selectable)
Amplitude compensation setting for specified harmonic
Auto Current Limitation
Auto Diagnosis and Protection
Overheat protection, heatsink exceeds 65℃, fans will be started automatically
Voltage loss protection(system voltage lower than UN85%), breaker carry out voltage loss proetction
Load over current protection
Compensation over current protection
System voltage protection
DC voltage protection
IGBT protection(IGBT inside temperature exceed 108℃, alarm IGBT fault)
2 times of IGBT rated current
Multi-Unit Operation Mode
Modbus RTU Protocol
Fiber or electrical connection
Intelligent wind cooling
≤65dB (A sound level)
