高压直流系统过负荷能力优化措施

HVDC System Overload Capacity Optimization Measures

考虑到高压直流输电系统单极故障会对另一极产生过负荷以及单极大地回线对周边电网和环境存在一定的影响,本文分析高压直流系统过负荷的设计方式和影响因素,在此基础之上提出针对区域性电网网架坚强的直流系统过负荷优化措施,并通过事例分析和统计总结验证此优化措施的必要性和正确性,为换流站运维提供了事故分析参考。

Considering that the single-pole fault of HVDC transmission system will cause overload on the other pole and that the single large loop has certain influence on the surrounding power grid and the environment, this paper analyzes the design methods and influencing factors of the HVDC system overload. On the basis of this, the paper puts forward a strong load optimization measure for DC system of regional power grid, and verifies the necessity and correctness of this optimization measure through case analysis and statistical summary, and provides an accident analysis reference for the personnel of the transfer station.
