-- 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 fluctuation
-- Secondary substation in city (66/110kv)
-- Hoist, and other heavy load
- 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 RXPE.
SVG Main Specialized Components
B. Power unit
C. Input reactor
D. Control cabinet
E. Full digital control system
F. NMI integrative workstation
SVG is the most advanced var compensator technologically, which realizes an evolution of reactive power compensation mode based on voltage source converter. Big volume capacitors and reactors are no longer needed. SVG uses HV IGBT or IGCT with high switching frequency to realize reactive power regulation. Therefore, SVG has the following advantages compared with traditional compensation methods:
--Faster response speed
--Stronger voltage flicker restrain capability
--Wide operation range
--Low harmonic content
A Top quality IGBT module for traction
--German EUPEC top quality IGBT modules
--Super capability of bearing high current and voltage spikes.
B Low inductance power capacitor
--High rated voltage and current.
--Long service life and free maintenance.
--Advanced performance at high temperature condition.
C Unique cooling design
--Advanced heat pipe design with high efficiency heat radiation technology.
--Eliminate heat-island effect of HV IGBT thoroughly.
D Low Voltage SVG Test Platform
The SVG test platform utilizes US TI TMS320F2812 type DSP as key controller to realize the following tests:
--Manually generate adjustable capacitive or inductive reactive power.
--Automatically compensate reactive power.
--Stabilize grid voltage.
--Compensate load harmonics.
--Compensate load unbalance
--Compensate reactive power, harmonics and load unbalance simultaneously.
