摘要
三沪直流工程系统调试分为2个阶段,共计完成试验项目238项,内容包括:初始化运行、保护跳闸功能、系统监控功能、电流控制、功率控制、无功控制、降压运行、辅助电源切换、交直流线路故障、本地/远端控制转换、功率提升/回降、直流额定功率运行和过负荷以及单项测试项目和测试结果。详细分析单极系统调试和双极系统调试对设备及其功能考核的结果,设备试验、分系统和站系统的调试结果,给出试验结论,最后得出系统的调试结论。
In the two stages of the system commissioning test of Throe Gorges-Shanghai HVDC Transmission Project, a total of 238 test items has been completed, including operation initialization, protective tripping, system monitoring, current control, power control, reactive power control, reduced voltage operation, auxiliary power switching, AC/DC line fault, local/romote control switching, power rise/drop, rated DC power operation, and overloaded DC operation, etc. Effects of monopolar and bipolar system trial tests on equipments and its functions are analyzed in detail. Equipment test, subsystem and station system trial test results are also analyzed and conclusions are made. Finally, conclusion to the system trial test is given.
