摘要
宁东—山东±660 kV直流输电示范工程是我国第1条660 kV电压等级的直流输电工程。该工程的成套设计由我国自主独立完成,是直流工程国产化的典范。为对其直流控制保护设备的整体功能及性能进行检验,并进一步校核成套设计成果的正确性,专门开展了二次系统实时仿真试验工作。对试验的整体情况进行了介绍,重点对试验中发现的关键技术问题及其解决策略、验证结果进行了阐述。二次系统实时仿真试验为宁东工程的现场调试工作和顺利投产奠定了坚实的基础。
The ±660 kV HVDC power transmission demonstration project from Ningdong to Shandong is China＇s first DC power transmission project in 660 kV voltage grade. The system design of this project is independently completed in China. To verify the overall functions and performances of DC control and protection devices for this HVDC power transmission project and further check the correctness of the system design, the real-time simulation tests for its secondary system are specially carried out. The overall situation of the simulation tests is presented, and key technical problems detected in the test and countermeasures to them as well as the verification results are expounded. Real-time simulation tests for the secondary system of the HVDC power transmission project lay down solid foundation for on-site commissioning and favoring putting into operation of the project.
