High Power Static Var Generator (SVG) – 3D Model SolidWorks

Static Var Generator, also known as Static Var Generator, or SVG for short, is a device that uses a free-commutation power semiconductor bridge converter to perform dynamic reactive power compensation. SVG is currently the best solution in the field of reactive power control. Compared with traditional phase-shifting devices, capacitor reactors, and traditional SVC represented by thyristor-controlled reactors TCR, SVG has incomparable advantages.
SVG uses turn-off power electronic devices (such as IGBT) to form a self-commutated bridge circuit, which is connected to the power grid in parallel through a reactor to appropriately adjust the amplitude and phase of the output voltage on the AC side of the bridge circuit, or directly control its AC side current. Rapidly absorb or emit the required reactive power to achieve the purpose of rapid dynamic reactive power regulation. As an active compensation device, it can not only track the impact current of the impact load, but also track and compensate for the harmonic current.
The cabinet of our company’s static VAR generator adopts the 90% profile imitation Rittal cabinet. Since the power of this static VAR generator is very large, in order to better dissipate the heat of IGBT, the radiator adopts a heat pipe radiator with better heat dissipation effect. In addition, the drawings also include reactors, capacitors, molded case circuit breakers, mutual inductors, etc.
