摘要(Abstract)：

介绍了舟山多端柔性直流输电工程舟洋换流站无源HVDC启动时的两起典型故障,分别为无源HVDC方式下直流控制保护系统手动切换试验失败、模拟阀控系统故障冗余切换试验失败。对故障原因进行了深入分析,并提出了解决方案。解决方案经试验验证有效,可作为后续柔性直流输电工程控制保护系统设计的参考。
Two typical faults occurred during the passive HVDC(high-voltage direct current) startup tests in Zhouyang VSC-HVDC(voltage source converter based high-voltage direct current) converter station are described in this paper. One is the failure of manual DC control and protection system switching and the other is redundancy switch test due to failure of simulated valve control system. The fault courses are deeply analyzed and the solutions are proposed. The solutions are validated and can be the reference of control and protection system design of follow-up VSC-HVDC projects.
