The low-voltage distribution automation terminal is an important part of the distribution network, which has the characteristics of multi-faceted and wide-ranging. With the great investment of CSG (China Southern Power Grid Company Limited) in distribution automation, the installation, debugging, operation and maintenance of the massive access of low-voltage distribution automation terminals difficult problems are particularly prominent. Therefore, this paper proposes a plug and play implementation method for station equipment based on IEC 61850. Firstly, a model design method based on the IEC 61850 standard is proposed to realize standardized access and communication point table configuration of end devices. Secondly, based on the model design method, a plug and play system and control of APP loading, unloading, and dynamic tracking of multiple instances are designed. The method realizes the standardization and uniformity of equipment communication, and ensures the safety, integrity and reliability of the replacement and access work of terminal equipment. Finally, the method proposed in this paper is applied to China Southern Power Grid to verify the advancement and feasibility of the method. The application results show that the method has a very positive guiding significance and reference value for practical problems such as complex on-site construction processes and cumbersome personnel operations.
