| 摘 要： | 基于PSCAD/EMTDC仿真软件,建立了特高压直流输电系统模型,详细介绍了特高压系统主电路及核心元件,如换流变压器、滤波器与无功补偿装置、直流传输线。在此基础上,根据华东电网特高压直流输电的系统的实际运行情况,搭建出相应的特高压直流与超高压直流多馈入测试系统。利用该系统对特高压直流系统的不同运行状态进行仿真实验,并针对特高压直流系统的几种典型故障测试进行仿真测试,将测试结果与特高压直流现场数据进行对比分析,结果表明该模型能很好地反映特高压直流输电系统的真实运行情况。 |

| Abstract: | A model of UHVDC transmission system is built based on PSCAD/EMTDC.Its main circuits and key components are introduced in detail,including converter transformer,filter and reactive power compensator,DC transmission line.A multiple feed-in test system is then established for UHVDC system according to the real operating conditions of the UHVDC transmission system in East China Power Grid,with which,various operating statuses of UHVDC transmission system are simulated and several typical faults of UHVDC transmission system are tested.The simulative results are compared with the on-site measured data of UHVDC transmission system and the results show that the model reflects very well the real operating conditions of UHVDC transmission system. |
| Keywords: | UHV power transmission DC power transmission electric filters converter transformer models computer simulation |
