| APF/SVG Functional Principle 1. Principle of filtering out harmonic APF / SVG acquires the current signal in real time through an external current transformer, and separates the harmonic part through the internal detection circuit, and generates a compensation current with the opposite phase of the harmonics in the system through the IGBT power converter to realize the function of filtering out harmonic. The output compensation current of APF/SVG varies accurately according to the dynamic harmonics of the system, so there will be no compensation problem. In addition, APF/SVG has overload protection function. When the harmonic of the system is larger than the filter capacity, the device can automatically limit the output of 100% rated capacity without overload. 2. Principle of compensating for reactive power According to the reactive power of the system, APF / SVG generates capacitive or inductive fundamental current through the IGBT power converter to achieve the purpose of dynamic reactive power compensation. The compensation target value can be set through the operation panel without overcompensation. The compensation is smooth and there is no inrush current impact on the load and the grid.. 3. Principle of compensating for three-phase unbalance The APF / SVG extracts the unbalanced component according to the system current, and the three phases emit a current of the same phase as the unbalanced component, and the unbalanced portion is compensated to zero, so that the three-phase unbalanced current can be corrected to the three-phase balanced current. |
