Introduction • iSVG iSVG series high-voltage static var generator is the most advanced third-generation static var generator device developed by INVT for power compensation and harmonics compensate. iSVG series products apply advanced chain topology and three data processing to ensure the stable operation, faster response, self-protection and reliable communication. The structure and installation of iSVG series products also facilitate the ordinary maintenance. • Main Functions As a compensation device based on big power inverter, iSVG series high voltage static vargenerator can be...

Urban Substations Current: City substation commonly used grading capacitor bank to compensate for reactive systems and improve power factor. This compensation method can only provide capacitive reactive to the system, not adjust with the change of he load achieve and it is easy to cause reactive transmission, raises the bus voltage and the hazards of electrical equipment and system stability. Solution: iSVG can rapidly perform capacitive and inductive reactive power compensation to stabilize the bus voltage , improve the power factor and avoid reactive transmission. Current: Arc furnace is...

Product Composition iSVG series high-voltage static var generator composes of switch cabinet, reactor cabinet, unit cabinet and control cabinet. • Switch Cabinet Switch cabinet includes isolated switch, AC contactors and current limiting resistor. iSVG applies self-motivation technology to make the impact current smaller. Isolated switch can disconnect the device from the system with the obvious point of isolation to ensure the maintenance of personnel safety. • Reactor Cabinet There is a three-phase AC reactor which connects the high voltage static var generator and power grid, buffers the...

Monitoring System Interface System Principle • Working Principle The commutation bridge circuit of iSVG series high-voltage static var generator is composed of IGBT. After parallel-connecting iSVG with the grid, the circuit can release or absorb reactive current through adjusting the phase and amplitude of output voltage or control the AC current. Non-load Operation Capacitive Operation Inductive Operation When U1 >US, iSVG equals to Us jxl l continuous X T adjustable ^/( capacitors. Ul jxl L When Ul <US, iSVG equals to continuous adjustable inductances.

• Main iSVG circuit uses chain topology connects in Y shape. • ThelOkV device applies 12 IGBTs for each phase and the 6kV device applies 8 IGBTs for each phase. Principles of Power Unit -> Power supply PCB- Optical Signal • The core of iSVG is the chain inverter based on IGBT. The inverter is composed of several parallel-connected IGBT. • The power unit applies PWM control technology to simplify the circuit and improve anti-interference capability and reliability. • The power unit can be changed with each other because they have the same electrical properties.
