摘要

针对特高压直流完全闭锁引起的交流系统暂态过电压问题

得出无功盈余量、短路容量是引起暂态压升的主要因素

计及无功补偿的容升效应与交直流系统间的无功交换

得出无功盈余量的计算公式并推导出换流母线暂态压升的计算方法。根据暂态压升表达式提出两个新指标用来衡量直流完全闭锁后的暂态过电压程度

并定量分析了闭锁容量与暂态压升的关系。最后基于DIgSILENT仿真平台

分别搭建CIGRE直流输电标准测试系统与新疆天中直流送端系统

仿真验证了暂态压升计算方法的有效性与正确性。

Abstract

In view of transient overvoltage problem of alternating current（AC） system due to complete blocking of after ultra-high voltage direct current（UHVDC） system

it is concluded that surplus reactive power and short circuit capacity are the main factors that cause transient voltage rise.Considering reactive power compensation capacity gain effect and reactive power exchange between AC and DC systems

the calculation formula of reactive power allowance is obtained and the calculation method of transient bus rise is derived.According to the c alculation method of transient voltage

two new indexes are proposed to measure the degree of transient overvoltage after the complete blocking of DC

and the relationship between the blocking capacity and the transient voltage rise is quantitative analyzed.Finally

the CIGRE DC transmission standard test system and Xinjiang Tianzhong DC transmission system are setup respectively on the basis of DIgSILENT simulation platform so to verify the validity and correctness of the calculation method of transient voltage rise.
