±100Mvar TSVG Series
The product description Data download

Maintain and control node voltage, improve system transient stability limit and reduce the amount of low pressure release load, and prevent transient voltage collapse, dynamically maintain node voltage transmission line, improve the steady-state transmission power transmission line limits;
On the load side, it can suppress the voltage flicker, compensate the load imbalance, improve the power factor, etc.
The system consists of pipe bus, starter cabinet, reactor, valve group container, control container and waterway system. Among them, the three valve sets of the container corner connection, through 35kV isolation knife to the 500/35kv special transformer low voltage side.

Technical advantages

The advanced professional container model is designed to adapt to the extreme weather conditions such as storm and desert
The innovation adopts FPGA to realize the system algorithm, which is more than the traditional SVG
Variable frequency speed regulation system, according to the chain section temperature automatically adjust the wind volume, reduce pollution, reduce noise, and save electricity
By means of independent control, harmonic extraction, full compensation mode, SVG has the function of reactive power compensation + harmonic control
TSVG high and low voltage cross control scheme to meet high and low voltage crossing requirements
The IGBT temperature is fully collected, and the temperature drop capacity can be achieved
