A new static var compensation topology arithmetic is proposed to meet the demand of harmonic suppression and dynamic continuous power compensation on industrial rectification system. It calculates the active power and reactive power of the net side of the rectification system on-line, which based on the three-phase circuit instantaneous reactive power theory. To provide fast and accurate real-time measurements of active and reactive for new type static var compensators, this paper designs a optimization digital low-pass filter with the approach by combining the Butterworth filters with mean filter. Simulation results by simulink proves the good dynamic response speed and stability of the optimization digital low-pass filter.
