Static var generator
AWSVG static var generator, a high-tech product that has many breakthroughs from conventional reactive compensation ideas, is widely utilized for reactive power compensation of electrical systems.
AWSVG adopts semi-conductor power electronic device to build rectification and inverter circuit. Continuous, dynamic and two-way reactive regulation may be realized for inductance and capacitance. Power factor is improved in a flexible and dynamic manner. Voltage fluctuation is restrained, resonance is avoided and unbalance reactive power is compensated by split-phase. Therefore, losses are reduced and energy is saved in a manner much better than conventional equipment.
AWSVG has better performances in terms of response speed, stable grid voltage, lower system losses, increased transmission capability, higher transient voltage limit, less harmonic and floor space.
