摘　　要：大区域电网间采用异步互联是未来电网发展趋势,直流输电技术是实现异步互联的关键技术。VSC-HVDC输电技术是直流输电技术的主要发展方向之一,与传统的较为成熟的PCC及CSC技术不同,基于VSC技术的交直流混联系统静态电压稳定性问题研究较少,对此问题进行较为深入的探讨,提出基于VSC技术的交直流混联系统静态电压稳定性分析方法,并使用算例进行AC/VSC-HVDC系统的电压稳定性计算,算例结果证实算法的可行性。Large regional power grid using asynchronous interconnection is the future trend of the grid.HVDC technology is a key technology to implement asynchronous interconnection.VSC-HVDC transmission technology is one of the main development directions of HVDC technology.It is different from the more mature and traditional PCC and CSC technology, there is few study of static voltage stability problems based on AC/VSC-HVDC system.So this paper has a more in-depth discussion with this problem,proposed an AC/VSC-HVDC power system static voltage stability analysis method. The feasibility of the algorithm,is confirmed by examples.
