Active filter, reactive power generator(APF, SVG)
Active power filter (APF) has multiple compensation modes, including harmonic control, reactive power compensation, unbalanced current compensation, on-demand distribution, and full range stepless compensation for reactive power. Having a comprehensive three-phase imbalance compensation strategy to achieve active/reactive/phase imbalance compensation
Excellent filtering performance
Simultaneously filtering out 2-50 harmonics and achieving comprehensive governance of odd and even harmonics, as well as setting the proportion of any single harmonic
Comprehensive equipment and system protection
Resonance protection, external electrical fault protection of equipment, internal fault protection of equipment, overcurrent protection, IGBT overheating protection, etc., automatic capacity reduction when the working environment exceeds the limit
High end quality of core components
Adopting imported IGBT, advanced three-level technology, high-end industrial control chip (28377) from TI in the United States, dual core 32-bit CPU+2CLA, with a main frequency of 200MHz and comprehensive functions
Humanized interactive experience
Through a graphical display interface, users can clearly understand the improvement of power quality in the system before and after compensation, including waveform diagrams, harmonic spectrum diagrams, effective current values, power factors, and other related aspects
Passive Filter (K-TFC)
The K-TFC intelligent controller adopts intelligent algorithms and encoding methods to control multiple sets of compensation filter banks for precise compensation, improving compensation accuracy, solving the problems of over compensation and under compensation, and ensuring that the power factor is always in the optimal compensation state. The measurement function includes: a three-phase four wire circuit or all phase voltage/line voltage (V), current (I), power (P, Q), power factor (COS Φ), frequency (F), harmonic (%), and harmonic bar graph analysis. It can measure up to the 15th harmonic and provide protection against total harmonic distortion rate of voltage.
Millisecond level triggering technology
The thyristor switch unit adopts precise zero crossing triggering technology, and when the filter bank is put into the power grid at a rate of 20mS, the current is smooth without impact
Low loss
The connection between the thyristor switch unit and the capacitor reactor group adopts a triangular connection, which can reduce the current flowing into the thyristor to 0.58 times that outside the angle
Powerful self checking system
The self diagnostic system can handle various faults, such as overcurrent, overvoltage, undervoltage, three-phase current imbalance, power phase loss, thyristor short circuit, thyristor open circuit, radiator overheating, fan failure, etc
Good scalability
According to the capacity of the device and compensation requirements, it can be divided into a main cabinet (i.e. the precise compensation cabinet is composed of filter compensation branches graded according to coding) and an auxiliary cabinet. The auxiliary cabinet is a supplement to the capacity of the main cabinet
