基于5G通信技术的含DG配电网差动保护控制方法研究
Research on differential protection control method for distribution network with DG based on 5G communication technology
摘要
Abstract
In response to the communication delay and delay jitter issues of existing differential protection methods for distribution network with distributed generation(DG),a differential protection structure for distribution network based on 5th-Generation(5G)communication technology has been proposed,combining 5G communication tech-nology with improved time dynamic bending algorithm for differential protection in distribution network with distribu-ted power sources.The dynamic time warping algorithm is optimized by introducing weighted functions and global path constraint strategies,improving protection reliability and calculation speed.The superiority of the proposed protection method is verified through example analysis.The results indicate that,the proposed method can quickly perform protection in differential protection,effectively reducing communication delay,delay jitter and protection action time,which is capable of adapting to future complex distribution network structures with distributed power sources,providing certain assistance for the development of 5G+smart electricity.关键词
