Recently, in particular, many of the coming hydro power projects in China are located far away from the load centers. As the use of HVDC transmission continues to develop situations have arisen where multiple HVDC links terminate in close proximity in a common AC system area. This paper refers to the methods to improve the stability of voltage on multi-infeed HVDC system, and using CRIEPI's transient stability simulation tool (CAPT). Through the simulations, this paper find the better measurement to solve those faults cases. Make a model multi- infeed system base on the China Southern Power Grid for system. We focused of the inverter side voltage, and compared this traditional control method with the rapid restart control method's results. The control of constituent HVDC subsystems can be better coordinated by the consideration of the time of rapid restart control at inverter side.
