摘要
特高压直流换流站的绝缘配合设计对特高压直流电网的安全运行和经济性有重要影响。本文依据缅甸水电送电广东相关规划研究,假设该工程采用±1 000k V特高压直流输电方式,设计了直流系统参数,搭建±1 000k V换流站直流暂态过电压仿真模型并进行暂态过电压计算。探索性研究了±1 000k V特高压直流换流站绝缘配合方案,初步提出换流站各点绝缘水平,分析了不同电压等级特高压直流换流站绝缘配合的特点。
Insulation coordination design of the UHVDC converter station significantly affects the safety and economy of UHVDC power system. Based on the transmission planning between Burma hydropower and guangdong power grid, supposed a ±1 000 k V UHVDC transmission project will be adopted, the main parameters of the DC system were designed and the transient simulation model of ±1 000 k V UHVDC power transmission system was built to research the DC transient overvoltage. The insulation coordination configuration of the ±1 000 k V UHVDC converter station was studied and the insulation levels of the UHVDC converter station were given. The insulation coordination characteristics of UHVDC converter station with different voltage level were also analyzed.
