摘要:
宁东—山东±660 kV直流输电示范工程中过电压与绝缘配合研究是工程的关键技术之一,对工程的可行性、可靠性、经济性有较大影响。文章针对宁东—山东±660 kV直流输电工程绝缘配合主要特点,结合具体的过电压电磁暂态仿真研究了系统工频、谐振、操作和雷电过电压水平,并根据计算结果提出换流站设备要求的绝缘水平,为工程设备配套提供依据。
关键词: 过电压, 绝缘配合, 避雷器, 绝缘水平
Abstract:
The overvoltage and insulation coordination are the key technologies in the Ningdong-Shandong ±660 kV HVDC transmission project, and have great influence on the feasibility, reliability, economy of the project. In this paper, combined with the insulation coordination features of the project, the power frequency, harmonic vibration, operation and lightning overvoltage level are analyzed by the overvoltage electromagnetic transient simulation. Based on the simulated results, the insulation level of equipment in converter station is determined, providing references for the matching of the engineering equipments.
