针对大型电网中区域性电网失稳的失步振荡问题，以华北2020年规划电网和东北电网2013年500 kV线路相间短路故障为研究对象，根据同调分群解列原理，提出了基于机组受扰轨迹同调分群的解列配置流程。结果表明：基于机组受扰轨迹同调分群的解列配置方法与常规解列配置方法相比，解列断面的设置思路更加清晰，并且，可以有效地解决多群振荡问题。%Aiming at the problem of out-of-step oscillation for regional power grid instability in large scale power grid, taking North China planning power grid in 2020 and phase-to-phase short-circuit fault of 500 kV power transmission line of Northeast China power grid in 2013 as the research objects, according to coherency identification islanding principle, puts forward the process of islanding measure configuration based on disturbed trajectory coherency identification of generators in actual power grid. The result shows that:compared with the conventional islanding configuration method, the islanding configuration method based on disturbed trajectory coherency identification of generators has two advantages:the way of the islanding section setting is more clear;and it can effectively solve the problem of multi-group oscillation.
