摘要
针对受端是弱交流系统的直流输电系统,上海-嵊泗直流输电工程为研究对象,模拟研究了如何通过调整控制策略,增加相应的频率控制环节,使受端为弱交流系统的直流输电系统在不同的运行方式要求下,随着系统动态负荷的增加稳定地起动。同时,研究中结合了系统无功能量平衡和系统运行稳定性的要求,分析了各设备状态,如滤波器、调相机和发电机等,最终在保证交流系统稳定、安全运行的同时得到受端为弱网的直流系统最优起动方式。
Taking Shanghai-Shengsi HVDC project as a studying object, this paper describes the start mode of HVDC system in which receiving system is weak AC system, by way of adjusting the control strategy and adding the link of frequency control to gain a steady start under different operation modes. Thinking of the reactive power balance and operation steady, the states of equipment, such as filters, synchronous condenser, generators, and etc, are studied carefully. Finally the optimal start mode of such HVDC project has been obtained on the basis of ensuring the AC-DC system to operate safely and steadily.
