嵊泗直流输电系统的调节方式研究

STUDY ON THE REGULATION STRATEGY OF SHENGSI HVDC TRANSMISSION SYSTEM

针对嵊泗直流输电工程逆变侧为交流弱网的特点 ,结合直流侧阀控及保护柜性能的闭环试验 ,对该工程直流系统的调节和交直流系统的联合调节作了分析 ,得出了直流系统控制方案、同步调相机及交流滤波器组的优化配置。试验结果表明 ,交直流模拟系统能够稳定运行 ,为实际系统联调试验奠定了良好的基础。

Based on the study of regulation strategy for the Shengsi HVDC project whose inverter side is a weak AC system,combined with the close loop test of its controlling and protecting devices, this paper analyzes the functions of the DC system regulation and the AC-DC system associated regulation. The results show that the AC and DC simulating system can operate safely and steadily with the optimized configuration of the HVDC system control strategy, the synchronous condensers and the AC filters. It provides the good basis for commissioning and testing on site.
