Abstract：Gansu dock at Guazhou Valley wind farm in the original fixed capacitor reactive power compensation performance defects and safety risks, proposed using dynamic reactive power advantage over the original SVG device reconstruction scheme of reactive compensation equipment。Introduced the Guazhou overview, features, and long-term planning in area power system, as well as the meaning and application of SVG. Analysis of response time and dynamic SVG devices to track time, discussed the use of SVG device smooth regulation of reactive power compensation fixed capacitor bank reform programme, combined with original features, practical effect. After the transformation, meeting the system requirements on the regulation of reactive power and voltage, but also for the future of the reactive power compensation of intelligentized reconstruction provides experience.
