  Application example Heavy industry loading like hoist, etc Hoist may produce following influences on power grid during work:     Cause power grid voltage fluctuation and voltage decline     Make power grid power factor lower     Increase equipment and electricity transmission wire consumption High voltage TSC dynamic reactive power compensation device improves system power factor and realizes energy-saving through fast compensation and stabilizing grid voltage.  Regional substation In regional grid, high voltage TSC dynamic reactive power compensation device can compensate system reactive quickly and accurately, improve system power factor and stabilize system voltage. Box-type substation High voltage TSC dynamic reactive power compensation device applies cabinet installation, which can be installed into box transformer substation system. It can compensate system reactive quickly and accurately, improve system power factor and stabilize system voltage. Power supply system of electrified railway Electrified railway uses AC power and its power factor is low. Applying high voltage TSC dynamic reactive power compensation device can compensate system reactive quickly and accurately, improve system power factor and stabilize system voltage. Wind power generation system Wind speed change causes wind turbine mechanical power changes, which further causes fluctuation of active and reactive output of generator. Thus, it leads to power quality decline and power factor decline. Applying high voltage TSC dynamic reactive power compensation device can compensate system reactive quickly and accurately, improve system power factor and stabilize system voltage. Long distance power transmission High voltage TSC can greatly improve the transmission and distribution performance of power system, and it has been widely recognized around the world. That’s to say, under different grid conditions, in order to keep a balanced grid voltage, we can install high voltage TSC in one or several suitable positions of the grid to achieve following targets:     Stabilize system voltage     Reduce transmission loss     Increase grid transmission capability. Let existing grid gives its fullest play.     Improve transient steady state limit     Increase power system damp       Technology
