Abstract

High Voltage Direct Current(HVDC) transmission projects has been playing crucial role in China Southern Power Grid(CSG). These projects transmit the numerous hydro electricity from Yunnan to Guangdong and Guangxi. Keeping these HVDC projects stabilized operating is important to the whole power grid. Different from Alternate Current(AC) transmission projects, 78% of debugging and checking work for HVDC devices is proceeding before being service as estimated, the commission work actually. The Lugaozhao HVDC project is ±500kV three-terminal HVDC project, which is updated from Gaozhao HVDC project. The multi-terminal project keeps operating normally in the following year after well designed field commission. The paper analyzed the rationality of field commission for multi-terminal HVDC project through the principles, contents and unexpected action in commission.
多端直流工程现场调试合理化研究——以卢高照直流工程为例
高压直流输电工程在南方电网中起着至关重要的作用。这些工程将大量的水电从云南输送到广东和广西。保持这些高压直流输电项目的稳定运行对整个电网至关重要。与交流输电工程不同的是,高压直流设备的调试和检查工作中有78%是在预计投入使用前进行的,实际是调试工作。鲁高照直流工程为±500kV三端直流工程,由高照直流工程改造而成。经过精心设计的现场调试,该多终端工程在第二年保持正常运行。本文从试运行原则、试运行内容和试运行中的意外行为等方面分析了多端直流工程现场试运行的合理性。
