Sinopak 3~11kV Indoor Air Cooled SVG
(Static Synchronous Compensator), also known as SVG (Static Var Generator)
SVG is a chain-type static synchronous compensator (STATCOM/DSTATCOM, also knows as SVG) —active dynamic reactive and harmonic compensation device at different compensation ranges.
SVG, different from impedance compensation (injecting or absorbing reactive power by capacitor and reactor) theory of traditional SVC, is based on voltage source converter, whose theory is equivalent to static synchronous condenser but whose performance is better than that of condenser and SVC. Especially, its operation range is wide, and its reactive compensation under low voltage is far greater than that of SVC.

Sinopak TSVG successfully realize high voltage active harmonic filtering function from 3kV~35kV according to many years experiences. It can eliminate harmonics from 2nd to 13th completely. Compared with traditional SVC, SVG adopted active components. TSVG is not only used for dynamic reactive power compensation equipment, but also used for high voltage active harmonic filtering equipment directly.
Sinopak TSVG adopts cascade topology, with lower output harmonic content and very good filtering effect.
High Quality Power Units Design for moisture-proof and dust-proof.
Fully closed design of power unit control panel ensures operation stability in humid, windy and dusty environment, Control drive board on power unit adopts silicone material with good performance for potting. The silicone can stay resilient and stable within -55°C~+180°C, and has better thermal conductivity and insulativity, ensuring stable operation of SVG in salt-spray environment.
2. Control Cabinet Design Advantage
Fully closed design
of control cabinet ensures use reliability in sand-dust or humid environment.
Fully closed design of control cabinet prevents external dust or soot from entering control cabinet. After being closed, it needs to receive heat dissipation; to ensure internal temperature within a reasonable range, upper and lower parts of control cabinet interior are respectively equipped with one fan for up-down and right-left circular flow of air in it so as to decrease the temperature.
Whole control system components are comprehensively screened, with low power consumption and high reliability, to improve whole system stability. Thermal simulation of FlOWTHREM software is used to control 67°C average internal temperature when external ambient temperature is 45°C so as to meet component temperature in service environment. It fundamentally solve dust prevention and pollution prevention problems.
3. Service Advantage
Power Module Tester
SVG mainly consists of many power modules, in order to help customers find module fault in time, Sinopak designed power Module tester, it is very easy and very fast to find the module faults.
By the way, Sinopak also install GPS module in SVG control room in order to help customer analyze SVG faults.
