柔性直流馈入下交流输电线路单端故障测距分析OA北大核心CSCDCSTPCD
Performance analysis of single-terminal fault location for transmission lines in an HVDC/AC interconnected power system
柔性直流输电具有不同于交流输电和常规直流输电的运行原理和特性,随着柔性直流输电技术的应用,交流电力系统的故障特征可能发生显著变化,基于传统交流系统暂态故障特征量的故障测距面临挑战.为此,基于柔性直流输电的运行原理,分析了柔直交流侧故障时换流器的运行特性,推导了在换流器保护未启动、限流以及闭锁条件下柔直交流侧短路电流解析式,分析比较了柔直不同暂态运行状态下对输电线路单端故障测距的影响规律.结果表明,柔直馈入下交流输电线路单端故障测距受换流器交流侧电…查看全部>>
The operation principle and characteristics of flexible high voltage direct current (HVDC) is different from conventional AC and DC transmission.With the application of flexible HVDC technology,the fault characteristics of AC power system may change significantly,and the fault location algorithms based on conventional AC power system face challenges.Therefore,based on the operating principle of flexible HVDC,the operation characteristics of converter w…查看全部>>
