SVG (Static Var Generator) and conventional capacitor bank are both devices used in power systems for reactive power compensation, but they have significant differences in terms of operation, performance, and flexibility. Here's a comparison between SVG and conventional capacitor bank: 1. Operation: - SVG: SVG uses power electronics-based technology to dynamically control and r...
The reactive power consumed by the transformer is generally about 10% to 15% of its rated capacity, and its no-load reactive power is about 1/3 of the full load. Therefore, in order to improve power factor (PF) of the power system, the transformer should not operate at no-load or in a long-term low-load operation state. Vigorously improving the power factor of transformers, reducing line losses, a...
