摘　　要：阐述惰速过程中频差和角差的变化规律,提出频差合格窗口和同期窗口的概念,给出并网成功与失败的确切定义。在此基础上,探讨并网成功率的具体计算方法,包括并网成功判据、并网失败判据,介于二者之间的判据,给出并网成功率计算公式,并对典型工程的并网成功率给出了计算算例。This paper describes the variation law of frequency difference and angle difference during the coasting process, proposes the concepts of qualified frequency difference window and synchronous window, and provides the exact definition of successful and failed grid connection. On this basis, specific calculation methods for the success rate of grid connection are explored, including grid connection success criteria, grid connection failure criteria, and criteria between the two. The calculation formula for the success rate of grid connection is given, and calculation examples are given for the success rate of grid connection of typical projects.
