【Abstract】 This paper investigates the effect of TCSC on improving transient stability through simulations when transferring power from west to east in Northwest power system. The main circuit configuration and the operation modes of TCSC are introduced first, then the static and dynamic model of TCSC are given. Through comparison of large quantities of simulation results in Northwest power grid, the site of installation and the capacity of TCSC is achieved. Test results show that TCSC can greatly improve the power transferring capability of Northwest power grid, and adopted control policy has obvious effect on improving system transient stability.更多还原
