继电保护仿真系统的研究

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.

Study on relay protection simulating system

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.
