建立了包括保护系统动态特性在内的电力系统动态分析的数学模型。方程的建立基于通过节点导纳矩阵Y/子母线/建立保护系统与系统其余动态元件之间的显式关系。通过将感兴趣的断路器表示为传输网元的一部分来实现该关系。保护继电器、重合闸继电器和断路器被建模为动态装置，利用相量状态变量跟踪这些装置对电压和电流输入的依赖关系。一个简单的例子说明了这些概念。作为分析模型的直接结果，引入了保护成功区域的概念，并讨论了它对稳定性分析、继电保护整定、自适应继电保护和串级跳闸的影响。>；
Mathematical models for power system dynamic analysis including the dynamics of the protective system are presented. The formulation of the equations is based on establishing explicit relations between the protection system and the rest of system dynamic elements through the node admittance matrix Y/sub BUS/. This relationship is achieved by representing the circuit breakers of interest as part of the transmission network elements. The protective relays, reclosing relays and circuit breakers are modeled as dynamic devices for tracking the dependence of these devices on the voltage and current inputs using the phasor state variables. A simple example illustrates the concepts. As a direct consequence of the analytical model, the concept of a protection success region is introduced and the implications for stability analysis, relay coordination, adaptive relaying and cascade tripping are discussed. >
