LC filter is an important part of this hybrid reactive power dynamic compensation. The parameters of capacitor and inductive winding of LC filter change during operation with the changing surrounding temperature, the self-heating and the insulation ageing of capacitor, etc. During the installation and commissioning, there may exist errors that can deviate the actual parameters and correspondent harmonic oscillation frequency from the designed value and result in filter disarrangement.

By defining a discriminability function and utilizing some images with synthetic defects, a parameter selection method is proposed to adapt to various fabric types when the Gabor filter bank is applied in defect segmentation. It is argued that only the real part of Gabor filter works during segmentation; the radial orientation can be limited to horizontal and vertical direction; the radial frequency and the length of the FIR filter should depend on the basic frequency of the fabric texture.
