我国第一组高温超导电缆的运行工况及损耗计算

Operation Condition Analysis and Loss Calculation for the First High Temperature Superconductor Power Cable System in China

介绍了普吉变电站的超导电缆系统的技术参数、结构和并网运行的基本情况,与美国、丹麦的同等项目做了技术指标的比较,并用Monoblock model、Bean model等方法对超导电缆的损耗进行了计算,电缆及系统各部分损耗的计算结果与实际运行数据相符,随着电缆长度的增加,超导电缆系统的节能效果将越来越明显,普吉超导电缆系统能够在自然条件及电网各种工况下完成电能的输送。

The structure, technical parameters of high temperature superconductor （HTS） power cable system of Puji substation, that locates in Yunnan province, China and put into operation since April, 2004, as well as its on-line operation condition are presented and the technical indices of this project are compared with these of coordinative items in United States and Denmark. The losses of superconductor power cable system are calculated by the methods such as Monoblock model and Bean model, the calculation results of losses in cables themselves and in other parts of superconductor power cable system coincide with the data from practical operation. Along with the increment of cable length the energy saving effect of superconductor power cable system become more and more evident. The high temperature superconductor （HTS） power cable system configured in Puji substation can transmit electrical energy under natural conditions and various operation conditions of power network.
