As a upgrade var compensator for substations, the svqr has remarkable advanteges in many aspects such as var compensation precision, , response speed, stabilization of system voltage, reduction of line losses, and enhancement of transmission capacity. Senbao developed, for the first time in china, the substation var compensator, svqr, whose output is changed by regulating voltage across the capacitor. The svqr has found wide applications in substations. With complete hv and lv testing beds and the-state-of-the-art dsp-based control system development system, senbao has gathered a large army of excellent professionls and has passed the national iso 9001 quality system certification. The svqr is widely applied not only for new substations, but also for upgrading of existing substations, transforming the existing manual 1-step tbb into an automatic 9-step voltage-regulating-type var compensator. Senbao svqr has been operating successfully at an altude of 4, 000 meters in the cold area of shangri-la, yunnan, way ahead of the domestic manufacturers of the like products.
