Embodiment Construction
[0143] Combine below Figure 1 to Figure 4 , the control method with fault diagnosis and automatic repair functions of the hybrid compensation system of the present invention will be described in detail with specific examples.
[0144] In the present invention, the structure of the hybrid compensation system is as figure 1 shown. The hybrid compensation system includes a static var generator 1 (Static Var Generator, SVG), and more than one thyristor switched tuned filter (Thyristor Switched Filter, TSF ) composed of a thyristor switching tuned filter group 2 (abbreviated as "TSF group") and a controller 5 . The static var generator SVG and each thyristor switched tuned filter TSF in the thyristor switched tuned filter bank 2 are connected in parallel to the power grid.
[0145] In the present invention, the static var generator SVG includes a three-phase voltage type inverter and a filter. As an embodiment of the present invention, the filter in the SVG can use a single in...
