摘　　要：提出一种利用区间算法评估复杂配电网可靠性的方法.为使网络简化,根据复杂配电网的特点,运用网络等值的方法通过进行向上等效和向下等效过程得到简单的辐射型网络.该算法对配电系统元件可靠性原始参数进行分析和处理,得到各元件的可靠性原始区间参数,在此基础上求出负荷点及系统的可靠性区间指标及停电经济损失区间值.应用该算法对RBTS-BUS2系统进行可靠性评估,结果表明该算法灵活、高效、有工程实用价值.An interval arithmetic based approach to evaluate the reliability of complex distribution networks is proposed. To simplify the network model, according to the complex distribution network characteristic,this paper obtains the simple radiation pattern network using the network-equivalent method through upward equiva- lent and the downward equivalent process. This algorithm analyzes and processes the primitive distribution system component reliability parameter, based on which it obtains various component reliability primitive interval parameters and working-out the load and the system reliability interval indices and the power cut economic loss interval value. Through the application of the proposed algorithm in the evaluation of RBTS-BUS2 system, the results show that this algorithm is flexible, highly effective, and has practical engineering value.
