Static Var Generator SVG
YTPQC-SVG static var generator is based on the principle of voltage source inverter, using insulated gate bipolar transistor (IGBT) to control the amplitude and phase of inverter AC voltage, so as to achieve the purpose of reactive power compensation and harmonic compensation . Due to the very high switching frequency of IGBTs (up to several tens of kHz), SVG can compensate for fast reactive loads and achieve a fairly high compensation accuracy. SVG is the best solution in the field of reactive power control.

SVG features and benefits
outstanding performance* Reactive power compensation: Cos Φ = 1.00.
* Continuous correction - stepless control. SVG controls from 0 – rated kVAr as a continuous range.
* Capacitance and inductance compensation: -1 to +1.
* Full correction in less than 5 ms. For highly dynamic loads with fast or large fluctuations in power factor, e.g. sawmills, cranes, welders.
* No overcompensation or undercompensation experienced by capacitor switching systems.
* Current unbalance correction can correct the load unbalance of all three phases.
compact high performance
* Compact high performance.
* Wall or cabinet installation with ultra-compact design.
* Modular design allows 600kVAr to be provided in a single cabinet.
* Can be incorporated into electrical switchboards.
Network friendly and highly stable
* Not affected by harmonic distortion, no harmonic resonance.
* Not affected by network voltage drops. Even at reduced network voltage levels, full reactive current can be supplied to meet operating conditions.
* No annoying transient voltage spikes due to capacitor switching.
* Presents to the grid as a very high impedance device. Network companies do not have to worry about attenuation of the ripple injected signal.
