STATCOM and synchronous generator are considered as measures of providing dynamic reactive power to power grid. Based on a real regional power grid, ability of voltage support between STATCOM and generator are compared through digital simulations. The results shows that STATCOM always provides additional reactive power to persist voltage collapse, while ability of generator reactive power are restricted by terminal voltage under faults.
