摘要
研究系统分析分布式能源接入对保护定值适应性、方向判别、孤岛效应及重合闸策略的影响机理,提出基于自适应保护定值整定、人工智能故障识别、分布式协同保护及数字孪生优化的应对策略。工程案例表明,优化后保护误动率降至3%,故障隔离时间缩短61.9%,证实策略具有有效性。
This paper systematically analyzes the influence mechanism of distributed energy access on protection setting adaptability,direction discrimination,islanding effect and reclosing strategy,and puts forward countermeasures based on adaptive protection setting,artificial intelligence fault identification,distributed cooperative protection and digital twin optimization.The engineering case shows that the misoperation rate of protection is reduced to 3%and the fault isolation time is shortened by 61.9%after optimization,which proves the effectiveness of the strategy.
