摘要
目前,国内高压直流输电技术分为两类:一是基于ABB、南瑞技术路线的限幅型直流,二是基于 SIEMENS、许继技术路线的选择型直流.前者已有成熟机电暂态仿真模型,而后者尚缺乏深入研究,通常以限幅型模型近似代替,仿真结果与实际尚有一定差距,难以满足电力系统安全稳定计算的需求.该文在总结直流输电系统机电暂态建模原则的基础上,建立了选择型直流的精细化模型;利用轨迹灵敏度筛选出需校核参数,提出了基于实测数据的关键参数校核方法;并在中国通用的电力系统暂态稳定程序(power system department power tools-swing transient,PSD-ST)中开发实现,最后利用厂家电磁暂态仿真结果验证了模型的正确性.该文成果可改善直流控制系统模型缺失、仿真能力受限问题,有效提升机电暂态仿真程序的仿真精度.
Abstract
At present,there are two HVDC technical routes of HVDC control system in China,one is the HVDC control system based on limit by the ABB,NARI,and the other is the HVDC control system based on selection by the SIEMENS,XJ.The former has got a mature electromechanical transient simulation model,while modeling of the latter still lacks in-depth researches.It is usually replaced by a HVDC control system model based on limit.There is still a great difference between the simulation results and the actual characteristics,which cannot meet the needs of the power system security and stability calculation.This paper summarizes the electromechanical transient modeling principle of the HVDC transmission systems,establishes a refined model of the HVDC control systems based on selection;The paper proposes a key parameter screen and verification method based on the measured data and the trajectory sensitivity.This new modeling method is implemented in the general power system simulation program PSD-ST in China.Finally,the correctness of the model is verified by the manufacturer electromagnetic transient simulation results.The results of this paper will solve the problem of the lack of HVDC control system model,and effectively improve the simulation accuracy of the electromechanical transient simulation program.
