Long-distance power transmission
Stabilization of weak system voltage
Reduced transmission loss
Increased transmission capacity, make the existing power grid play maximum efficiency
Increased transient steady limit
Increased damping under small interference
Better voltage control and stability
Less power flunctuation
Secondary substation in city (66/110kv)
In regional power grid, the reactive power compensation of the system and improved power factor commonly achieved by TSC, which can only provide capacitive reactive power to the system, but can not achieve rapid and precise regulation along with the change of load, at the same time to ensure power factor of bus, it is easy to cause inverted sending reactive power to the system, raise the bus voltage, endanger electrical equipment and stability of the system. The SVG system of Shanghai Metal can quickly and accurately make capacitive and inductive reactive power compensation, when SVG stabilize bus voltage and improve the power factor, at the same time, it thoroughly, easily solves the problem of inverted sending reactive power.
Hoist, and other heavy loads
Hoist, and other heavy loads will cause the following impacts to the power grid at work:
Cause voltage level drop and voltage fluctuation in the power grid.
Power factor is low.
Transmission device will cause harmful high harmonic.
Above problems can be solved perfectly after installation of SVG of Shanghai Metal.
Solve the following problem for factories:
•Large voltage fluctuation
•Low power factor is lower
•Serious voltage flicker
•High-order harmonics, leading to voltage distortion
•Serious three-phase unbalance of the grid results negative sequence current
