2. Unified power flow controller - Wikipedia

   en.wikipedia.org/wiki/Unified_Power_Flow_Controller

   A unified power flow controller (UPFC) is an electrical device for providing fast-acting reactive power compensation on high-voltage electricity transmission networks. It uses a pair of three-phase controllable bridges to produce current that is injected into a transmission line using a series transformer. [ 1 ]

4. Voltage control and reactive power management - Wikipedia

   en.wikipedia.org/wiki/Voltage_control_and...

   The task of additional reactive power compensation (also known as voltage compensation) is assigned to compensating devices: [7] passive (either permanently connected or switched) sinks of reactive power (e.g., shunt reactors that are similar to transformers in construction, with a single winding and iron core [9]).

5. Static synchronous compensator - Wikipedia

   en.wikipedia.org/wiki/Static_synchronous_compensator

   In Electrical Engineering , a static synchronous compensator (STATCOM) is a shunt-connected, reactive compensation device used on transmission networks. It uses power electronics to form a voltage-source converter that can act as either a source or sink of reactive AC power to an electricity network.

   Solid Converter PDF is document reconstruction software from Solid Documents which converts PDF files to editable formats. Originally released for the Microsoft Windows operating system, a Mac OS X version was released in 2010. The current versions are Solid Converter PDF 9.0 for Windows and Solid PDF to Word for Mac 2.1.

7. Flexible AC transmission system - Wikipedia

   en.wikipedia.org/wiki/Flexible_AC_transmission...

   Heavily loaded lines consumed reactive power due to the line's inductance, and as transmission voltage increased throughout the 20th century, the higher voltage supplied capacitive reactive power. As operating a transmission line only at it surge impedance loading (SIL) was not feasible, [2] other means to manage the reactive power was needed.
