摘要
文中以探究同塔架设的两回直流系统之间的相互影响特性为出发点,借助实际控制保护系统与实时数字仿真工具RTDS构成的闭环仿真系统对葛南与荆沪同塔双回直流输电工程的各种运行工况与故障进行了详细的仿真研究。进一步研究了相对于常规单回架设方式,直流系统采用同塔双回架设方式对各回自身暂态特性的影响情况,并针对同塔双回架设的方式可能出现的几种特殊故障进行了特征研究。仿真结果和研究结论对同塔双回直流输电工程控制与保护系统的功能设计和参数整定提供了有效而可靠的依据。
In order to explore the interaction characteristics of double circuit on same tower,based on the closed-loop simulation system consisting of the actual control and protection system and real time digital system(RTDS),many kinds of operation conditions and faults of the Genan and Jinghu ±500 kV double circuit HVDC power system are analyzed.Compared with the conventional single transmission line,the influences of the double circuit HVDC system to their own transient characteristics are studied,and some possible faults are also analyzed.Simulation results and conclusions can provide effective and reliable basis for the functions design and parameter setting of double circuit HVDC power system.
