Web16.22 High-Voltage Direct Current Interruption. High-voltage direct current (HVDC) lines are used as links in AC transmission systems for several reasons such as stability, economy, and corona loss. It is possible to control the current on the HVDC side by use of firing circuits of the thyristors used in both rectifiers and inverters. Web13 Sep 2024 · With classic HVDC, the reactive power cannot be controlled independently of the active power. VSC-HVDC makes it possible to control the reactive power and the active power independently. The reactive power flow can be controlled separately in each converter by the AC voltage that is requested or set manually without changing the DC voltage. the boultings
