摘要:
系统带电调试试验是确保柔性直流输电工程在实际应用中安全稳定运行的一个关键环节。为了避免现场有源初次启动过程中因故障、阀组触发相序错误等问题导致换流阀设备的损坏,结合厦门真双极柔性直流输电工程,提出了初次完整启动前开展换流阀无源逆变试验的安全控制策略,很好地满足了设备安全性的要求。对实验室系统联调及现场试验过程中发现的主要问题进行了分析总结并提出了改进措施,满足了系统安全稳定运行的要求。

Abstract:
The system live commissioning test is a key process to ensure the secure and stable operation of flexible HVDC power transmission project in its practical application. In order to avoid the damage of converter valves caused by faults and trigger phase sequence errors of valve groups in the initial active start-up process and combined with the Xiamen real bipolar flexible HVDC power transmission project, a security control strategy for passive inverter test of converter valves before the initial total start-up is proposed to meet the safety requirement of equipments. The major issues found in the lab system alignments and field tests are analyzed and summarized, and the improvement measures are put forward to meet the requirements of safe and stable operation of the system.
Key words:  flexible HVDC power transmission  converter transformers  converter valves  passive inverter  deblocking
