配合系数与网络结构关系的研究

STUDY ON RELATION BETWEEN NETWORK TOPOLOGY AND COOPERATION COEFFICIENT

根据整定计算实践中出现的有关配合系数的普遍现象 ,论证了不同运行方式和不同故障点对配合系数大小影响的一般规律。并给出选取最保守配合系数的运行方式和故障点的捷径 ,利用这些结论可以减少计算工作量 ,提高整定计算的工作效率 ,并且加深对配合系数概念的理解 。

According to the general phenomena appeared in the calculation of relay setting. the paper discusses the generalconclusion about the cooperation coefficient affected by different operating modes and fault points. A short--cut is given forselecting the operating modes and fault points which are necessary to consider for calculating the most conservativecooperation coefficient. Using this conclusion. we can reduce the calculation burden and enhance the efficiency of settingcalculation. And also it is very helpful to reduce the blindness of calculation by deepening the understanding of the concept ofcooperation coefficient.
