Reactive Power Compensation and Filtering Device
The MDQG series Reactive Power Compensation and Filtering Device adopts a reactive power compensation method different from traditional capacitor-reactor combinations that utilize inverse-phase physical characteristics. MDQG generates reverse reactive current through IGBT control to neutralize the reactive current in the power distribution system, thereby achieving effective reactive power compensation.
Product Features
• Smooth and stepless compensation, achieving a power factor close to 1.00 (≥0.99) throughout the entire range
• Capable of bidirectional inductive and capacitive compensation from -1.0 to +1.0, suitable for both traditional inductive loads and capacitive applications such as IDCs
• Based on IGBT technology, it is a controllable current source type compensation device
• Automatically tracks load changes with a total system response time ≤10ms
• Modular design with parallel operation mode, easy to expand
• Multiple control modes to suit various application environments
• Equipped with multiple protection functions: overcurrent, overvoltage, undervoltage, phase loss, etc.
• Harmonic compensation function, capable of filtering harmonics from 2nd to 50th order, with a total harmonic compensation rate ≥95%
• Uses DC capacitors for enhanced stability
• HMI provides graphical and tabular interface for intuitive system operation monitoring
• Equipped with RS485 communication interface for data exchange with HMI
