中文摘要：
交直流系统之间的相互作用，尤其是与弱交流系统连接时，会带来电压不稳定、动态不稳定等一系列问题。受端系统为弱系统时，换流站交流母线的电压稳定性成为困扰直流输电系统正常运行的一个重要问题。在以往研究的基础上，提出了一种判断交直流互联系统逆变站换流母线动态电压稳定性的判据，该判据简单且判断速度较快。利用BPA仿真软件，对两端直流系统（以下简称2DC系统）直流闭锁故障时的换流母线动态电压稳定性进行了分析，研究结果验证了判据的有效性和合理性。
英文摘要：
The interactions between AC and DC systems, especially when connecting with the weak AC system, will cause a series of problems such as voltage instability, dynamic instability and so on. When receiver system is weak, the voltage stability of AC bus in converter station becomes one of important items of HVDC transmission system. On the basis of some former research, a criterion is presented to judge the dynamic voltage stability of commutation bus in inverter station of AC/DC hybrid power system. This criterion is simple with fast determination speed. Using BPA to analyze the dynamic voltage stability of commutation bus for DC block faults in 2DC system, it verifies that the criterion is of validity and rationality.
