Product concept:
Working principle
The active filter cabinet detects the harmonic current in the power grid in real time through the internal power electronic devices, and then generates a compensation current equal to the harmonic current and opposite to the direction, and injects it into the power grid, thereby achieving the purpose of harmonic cancellation and filtering out harmonics. At the same time, it can also dynamically compensate for reactive power as needed to improve the power factor.
Structural composition
Controller: It is the core component of the active filter cabinet. It is responsible for real-time monitoring and analysis of the current in the power grid, and generates control signals according to the set parameters to control the operation of the inverter.
Inverter: Converts DC power into AC power and generates a compensation current opposite to the harmonic current. Inverters usually use power electronic devices such as insulated gate bipolar transistors (IGBTs), which have the advantages of fast switching speed, high efficiency, and strong reliability.
DC capacitor: It is used to store electrical energy and provide a stable DC power supply for the inverter. At the same time, DC capacitors can also play a role in smoothing DC voltage and reducing the impact of voltage fluctuations on the inverter.
Input and output reactors: Input reactors are used to limit the current flowing into the active filter cabinet to protect the equipment from the impact of short-circuit current; output reactors are used to filter out high-frequency harmonics in the inverter output current and improve the quality of the compensation current.
Performance characteristics
Fast dynamic response speed: It can quickly track the harmonic changes in the power grid and achieve effective compensation of harmonics in a short time.
High compensation accuracy: It can accurately detect and compensate harmonic currents, control the harmonic content at a very low level, and meet the requirements of various power equipment for power quality.
Versatility: In addition to filtering harmonics, it can also perform reactive power compensation, unbalanced current compensation, etc. at the same time, with the characteristics of multiple functional integration.
High reliability: It adopts advanced power electronics technology and reliable hardware design, has multiple protection functions such as overcurrent, overvoltage, overheating, etc., and can operate stably in harsh working environments.
Strong flexibility: It can be customized according to different power grid parameters and user needs to adapt to various complex power system conditions.
