摘要

对于远距离、大容量、交直流并联运行电网

交直流控制保护的配合对电网的安全稳定有着重要的影响。直流基频和二次谐波保护是交直流系统间相互配合的基本保护功能。利用EMTDC仿真软件和实时数字仿真（RTDS）对交直流混合运行电网中直流系统50 Hz和100 Hz保护整定原则进行了深入研究

提出了与交流系统故障清除时间和直流主设备承受能力相配合的100 Hz保护整定原则。

Abstract

The cooperation of AC-DC control and protection functions has important influence on the security and stability of the power system with the characteristics of long-distance

high power and combined operation of AC/DC.HVDC fundamental and second harmonic protections are the basic cooperation function between the AC and DC system.The 50 Hz and 100 Hz protection setting principles of the AC/DC hybrid transmission system are studied through EMTDC and RTDS simulation.The setting method based on the longest clearing time of AC faults and the overload capability of the HVDC main equipment is proposed

and the quantitative method based EMTDC simulation is presented.
