谐振接地系统的高阻故障选线是配电网故障诊断的传统难点。传统故障选线方法,一方面
因过渡电阻升高带来的特征原理性变化或对测量精度较敏感而可靠性不足;另一方面
因缺乏对分布式电源接入以及配电网多变运行方式下的特征机理研究而导致对实际场景的适用性不强。文中探讨了高阻故障非线性介质击穿原理和信号宽频化特点;建立了有源配电网高阻故障这一非线性系统的分析模型和宽频信号描述方法;讨论了故障的非线性特征在不同脱谐度、阻尼率等系统运行方式下的空间分布规律。最后,提出基于频段零序无功功率的高阻故障选线方法。仿真和实际故障案例验证了算法的有效性。
The high-resistance fault line selection of resonant grounded system is the traditional difficulty in fault diagnosis of distribution networks. On the one hand
the reliability of the traditional fault line selection method is insufficient due to the change of characteristic principle caused by the increase of transition resistance or the sensitivity to measurement accuracy. On the other hand
due to the lack of research on the characteristics and mechanism of distributed generation integration and variable operation modes of the distribution network
the applicability to the actual scenario is not strong. The principle of high-resistance fault nonlinear dielectric breakdown and the characteristics of broadband signal are discussed. The analysis model of the nonlinear system with the high-resistance fault in the active distribution network and the description method of the the broadband signal are established. The spatial distribution of the nonlinear characteristics of the fault under different operation modes such as detuning degree and damping rate is discussed. Finally
a high-resistance fault line selection method based on zero-sequence reactive power in the frequency band is proposed. The effectiveness of the algorithm is verified by simulation and actual fault cases.
