SVC and STATCOM are two types of power electronics devices used for reactive power compensation in power systems. While both devices serve a similar purpose, there are significant differences between them in terms of their operation, control, and application.

Static synchronous compensator (STATCOM) is the core of flexible AC transmission system. This article will introduce the control mode of STATCOM.

In general, STATCOM is a solid-state switching converter. When its input end is connected with a power supply or energy storage device, its output end can independently send or absorb controllable active and reactive power. Compared with traditional reactive power compensation devices, STATCOM has t
