With the truth that the essential carrying limit of transmission element is its permissible operating temperature,a contingency screening and ranking method based on the temperature of transmission element is proposed.
本着输电元件载荷限制的热本质因素,提出以输电元件温度为核心的事故筛选和事故严重性程度排序方法,该方法以预想事件发生后电力系统中各输电元件的稳态温度值是否超过其最大允许运行温度为事故筛选标准,进而对造成输电元件过载者按其温度到达其允许值所持续时间长度作为事故严重性程度排序指标,建立系统的评价方法。
3.
The aim of contingency screening and ranking is to reduce the number of contingencies needing detailed analysis and meet the requirement of dynamic security assessment with the selection of severe contingencies or the screening of harmless contingencies.
本文对目前的暂态稳定性分析的事故筛选与排序方法,如能量函数法中的PEBS法、基于扩展等面积法则的EEAC法及集中反应事故性能指标的方法进行了总结,并对各类方法进行了对比。

补充资料：DSH回转移动式筛选机
1、工作原理：本机座平面上有一个主动轴和四个从动轴托起筛箱，转动的曲轴带动筛箱作回转运动。形成多方位的贯力。使物料在筛网面上翻滚，移动。在每层网架与流料板之间装有网孔式托板及弹球，避免网孔堵塞。筛箱内的网架及流料板与平面相对为斜面，引导筛选物料移动方向，使粗、细物料自动流入下层网面或自动排出。
2、机器特点：
1、单机/小时处理量大，20目-40目，每小时可筛分15吨-20吨;
2、筛网使用寿命长;
3、筛分灵活方便，可同时筛分4种目数，也可以一种目数4次同时筛分;
4、密封性能好，噪音低、省工、省时;
