摘要
对系统调试过程中解决的主要技术问题进行分析概括,涉及系统调试方式计算分析、编制系统调试方案和试验项目科学优化组合。解决直流输电工程接地极电流对交流系统影响问题,保证直流大功率下单极大地回线和金属/大地回线转换等试验项目的圆满完成。自主开发的新型短路试验装置提高了短路试验的效率和安全性。研究无功控制交流滤波器投切逻辑,并提出了完善建议;对阀控制保护软件投旁通对控制逻辑和直流控制保护其他功能提出了完善意见。
The main technical problems of Three Gorges to Guangdong （3GG） HVDC project system commissioning test were summarized and analyzed. These contents included the mode calculation and analysis of system commissioning test and test programs. The influence of ground electrode current on AC system transformer was solved to guarantee the monopole high power test successfully with ground return and metallic return configuration. The development of new AC/DC line ground test device improved the safety and benefit of AC/DC line ground fault test. Reactive power control test, AC filter switching control test and other control and protection performances were carried out, and the related suggestions were presented. These technical problems were solved during system commissioning test, which guaranteed to complete system commissioning test and put this project into operation.
