| 摘 要： | 提出采用一种基于高温超导直流输电的长距离大容量联络线输电方案,并对该方案的实现进行概念性设计,建立相应的模型。在该模型基础上结合CIGRE标准高压直流输电模型参数,对系统的性能进行量化评估。采用高温超导技术可以在较低运行成本的情况下大大降低长距离输电带来的损耗,但是输电线路电阻的下降造成输电系统对整个电力系统的阻尼不足。为此,根据简化的模型讨论输电系统电阻对系统阻尼的影响,并采用Matlab/Simulink!对输电性能进行仿真研究,为超导直流输电系统控制系统的设计提供初步的依据。 |

| Abstract: | A superconducting DC power transmission scheme was proposed for long-distance tie-line power transmission. The conceptual model and mathematical model were built. Based on the model and CIGRE HVDC benchmark model, quantitative performance assessment was performed. Use of high-temperature superconducting (HTS) transmission can greatly reduce the transmission lost at comparatively low operation cost. However, HTS cannot provide enough damping for a superconducting power transmission system. The effect of the transmission resistance on the damping based on a simplified model were discussed. Power transmission performance was studied by performing numerical simulations under a Matlab/Simulink(r) environment. The simulation results can provide useful information for the control system design. |
