摘要
为了研究特高压直流输电工程在运行过程中电气量的变化特性,需要搭建一个比较准确的仿真模型。在参考CIGRE HVDC标准模型控制策略的基础上,结合已经投入运行的云广±800 kV特高压直流输电系统实际工程参数,建立了仿真模型。利用该模型进行正极、双极全压两种运行方式下的仿真试验,将仿真结果与云广特高压直流输电系统实际运行参数对比可知,仿真模型能够较好地模拟云广特高压直流输电系统正极、双极全压运行方式。建立的模型具有较高的可信度,能够作为进一步研究云广特高压直流输电工程其他运行工况的有效仿真工具。
In order to study the changing characteristics of electrical variables during the operation process of UHVDC system, a more accurate simulation model should be established. A simulation model is established based on the reference of the control strategy of CIGRE HVDC standard model and by combining with actual project parameters of Yun-Guang ±800 kV UHVDC system which has been put into operation. Simulation tests under positive polar, bipolar with full voltage operation modes are simulated by using the model. By comparing simulation results with actual operation parameters of Yun-guang UHVDC system, it is found that the simulation model can well simulate the positive polar, bipolar with full voltage operation modes of Yun-guang UHVDC system. The established simulation model has higher credibility, which can be used as an effective simulation tool for the further study of other operation conditions of Yun- guang UHVDC project.
