摘要: 构建了电网的加权动力学模型，以IEEE14节点标准测试系统为基础，对网络的拓扑结构和网络特性间的内在联系进行了深入研究，从耦合强度、功率扰动以及发电机的入网方式等方面研究了系统的自同步能力，并对影响系统同步稳定性的因素进行了分析。Abstract: Weighted dynamic model of power grid was built, and network topology and intrinsic link between characteristics of the networks were in-depth researched based on IEEE14 nodes standard test system. The capacity of self synchronization of system was studied from aspects of coupling strength, power disturbances and different ways of generator accessing into power grid, and factors affecting the stability of the system were analyzed.
