active power filter connected to the grid in Parallel, real-time test load harmonics and reactive components, using of PWM conversion technology, put the currents with the same size in opposite directions of the harmonic and reactive component into the supply and distribution system , to achieve harmonic suppression, dynamic reactive power compensation functions.

Technical Features

• Real-time following, dynamic compensation
Using detection technique based on instantaneous reactive power theory of harmonic current ,detect harmonic current in real time .tracking control instantaneous current , to achieve compensation for dynamic harmonic current ,tracking harmonic changes automatically ,with highly controllable and fast response.
• Flexible compensation
A machine can not only deal with harmonics , but also compensate for reactive power, improve power factor. it can not only separate compensation for a single harmonic source, but also focus on compensation for multiple harmonic sources. At the same time It can deal with specified harmonic harmonic . Also Can be used as a harmonic source.

• DSP intelligent monitoring
DSP high-speed testing and operations, to ensure the control of harmonic detection and compensation effectively and precisely; intelligent monitoring, device control flexibly, operating parameters and working status is showed; automatic fault diagnosis; with a remote communication interface, real-time monitoring by a PC.

• Advanced power conversion design
Using the latest high-frequency switching of IGBT devices, The main circuit topology is three-phase full-bridge PWM converter control with small size, high efficiency, high reliability, advanced technology to achieve multi-machine capacity expansion.

• The modular design of the standard
Power circuit and control circuit are module or group (plug) pieces of structure, improving the reliability and maintainability while standardized production .
