  which are significantly different from that of conventional synchronous generators. The performance of conventional percentage restrained differential protection is facing challenges. In order to solve this problem, this paper proposes a pilot protection method based on Spearman rank correlation coefficient for transmission lines. When the system operates normally or an external fault occurs, a traversing current is flowing through the transmission line, so the current waveforms on both sides are completely opposite. When an internal fault occurs, there are huge differences between the transient current waveforms on both ends. Therefore, the Spearman rank correlation coefficient can be used to measure the correlation degree between the current waveforms on two ends, to distinguish the faults inside and outside the zone. The method is suitable for all kinds of renewable energy power plants, and has good performance on tolerating transition resistance and noise. Compared with the existing protection based on fault characteristics of renewable energy sources, the proposed method also shows good operation performance when the output power of renewable energy sources is weak and the breaker recloses into a permanent fault. Both simulation results and field recording data verify the effectiveness of the proposed method.

摘要

随着逆变型分布式电源大量接入配电网，配电网运行方式灵活多变，给基于定值的三段式电流保护带来了挑战。同时

因配电终端和局域通信易受影响，基于局域通信协作的保护获取的量测数据可能存在缺失及错误问题，影响保护的动作性能。为此，提出了计及量测数据缺失及错误的配电网电流保护自适应整定方法。首先，通过多点量测信息实时感知配电网运行状态，并生成含实时拓扑信息的关联阻抗矩阵，经迭代计算后自适应调整保护定值，从而使得所提保护能够自动适应配电网运行方式的动态变化；然后，提出改进的基于Wasserstein距离生成式对抗网络的缺失数据重构与异常数据修正算法，解决了基于局域通信的配电网自适应电流保护存在的量测数据丢失及错误；最后，通过仿真验证了所提方法的正确性及有效性。

Abstract

With a large number of inverter-interfaced distributed generation connected to the distribution network

the operation mode of the distribution network is flexible

which brings challenges to the three-section current protection based on the setting. At the same time

because the distribution terminal and local communication are vulnerable

the measurement data obtained by the protection based on local communication cooperation may be missed and incorrect

affecting the operation performance of the protection. Therefore

an adaptive setting method for the over current protection in the distribution network is proposed

which takes into account the measurement data missing and error. Firstly

the operation status of the distribution network is sensed in real time through multi-point measurement information

and the correlation impedance matrix containing real-time topology information is generated. After iterative calculation

the protection setting value is adjusted adaptively

so that the proposed protection can adapt to the dynamic change of distribution network operation modes. Then

an improved algorithm for reconstruction of missing data and correction of abnormal data based on the Wasserstein generative adversarial network (WGAN) is proposed to solve the problem of measurement data missing and error in adaptive over current protection of distribution network based on local communication. Finally

simulation results verify the correctness and effectiveness of the proposed method.
