【摘要】 继电保护仿真系统是DTS中一个重要的组成部分。综合了逻辑判断仿真法和保护定值判断法的优点,提出了新的仿真方法,首先建立了各种保护类型的保护模型,基于广度优先搜索法提出了保护动作域的概念,在确定的保护动作域基础上进行定值判断,提高了仿真速度及逼真度。经过某实际电网中应用,取得较好的效果。更多还原

【Abstract】 Relay protection simulating system is an important part of DTS.A new type of simulating method was put forward by integrating advantages of logic judgment simulating method and judgment method with protection fixed set-point.First the various protection models corresponding to all protection types were built up,next the idea of protection action domain based on breadth-first search technique was put forward,last the fixed set-point judgment was carried out based on the protection action domain determined,by which the simulating speed and the fidelity were improved.The results applied to a power grid showed that it is feasible and effective.更多还原
