Long distance power transmission

The application of SVC in high-voltage power transmission network can significantly improve the transmission and distribution performance of power system. SVC installed at one or more suitable locations in the power grid can stabilize the voltage of weak system, increase the damping under small interference, improve the transient steady-state limit, increase the transmission capacity, maximize the efficiency of the existing power grid but reduce the transmission loss. In addition, the installation of SVC system in the power distribution network can also effectively improve the voltage stability of the power distribution network and greatly reduce the voltage fluctuation .

SVC can significantly improve the transmission and distribution performance of power system. SVC installed at one or more suitable locations in the power grid can achieve the following purposes:

■ Stabilize the voltage of weak system

■ Reduce power transmission loss

■ Increase the power transmission capacity to maximize the efficiency of the existing power grid

■ Improve transient steady-state limit

■ Increase the damping under small interference

■ Enhance voltage control and stability

■ Buffer power oscillation

The installation of SVC system also provides a solid technical support for the grid-connected operation of  in China.


SVC used in power system, especially in power transmission network, often adopts TCR + TSC + FC architecture:
