摘要：With the large-scale and large-capacity operation of HVDC transmission, the operating characteristics of the receiving-side power grid have changed significantly. In order to improve the dynamic recovery performance of HVDC transmission system, it is urgent to configure dynamic VAR compensation device in the system inverter Station. In this paper, the PSCAD/EMTDC electromagnetic transient simulation software is used to study the dynamic recovery performance of HVDC system for several different var compensating devices in HVDC inverter. In the case of HVDC inverter station commutation bus short-circuit fault, the effect of static var compensator (SVC), fixed capacitor (FC) and synchronous compensator (SC) on system power recovery is studied. The research results show that fixed capacitors have a certain effect on system fault recovery; SVC can effectively improve the voltage level after the fault but its effect and response speed are not as good as SC, At the same time, a large number of TSC will weaken the strength of the AC system; Synchronous compensator can quickly provide emergency reactive support for the system, accelerate system recovery, and enhance system strength, with obvious advantages.
