Overview of APF series active power filters

The main circuit of our active power filter (APF) is IGBT power converter, which adopts the detection technology based on the instantaneous reactive power theory to automatically track the harmonic changes of the power grid, and has high controllability and fast response. It overcomes the disadvantages of the traditional passive filter, such as poor filtering effect, easy resonance, and only fixed harmonic compensation, and can play a good filtering and compensation effect for all kinds of fast transient impact loads.

APF series active power filter adopts military-grade control chip, strong computing power and anti-interference ability, can realize a controller to control multiple active power filters in parallel, using adaptive current average value control algorithm combined with LCL topology. It overcomes the shortcomings of traditional hysteresis current control, such as wide range of output spectrum, difficult filtering and interference of high frequency harmonics due to switching frequency change.

SVG series static reactive power generator overview

At present, in practical application, the traditional reactive power compensation adopts the mode of grouping capacitor switching by slow switching equipment, which has range, poor compensation accuracy and slow response speed. SVG uses the way of compensating current generated by high-speed switching devices, there is no problem of compensation accuracy, and the response speed is fast.

Overview of TSVG series hybrid dynamic reactive power compensation devices

Traditional compensation devices use capacitors to provide reactive power, capacitor group capacity is fixed, the output capacity is different, it is difficult to achieve the reactive power safety balance with the system, and the cost of large-capacity SVG is very high, so our company has developed TSVG after years of practice and exploration, using small-capacity SVG and large-capacity TSC combination. It saves the cost and achieves the effect of fast SVG response speed and stepless compensation, and the reactive power capacity ensures continuous adjustment and smooth output.
