摘要/Abstract

摘要： 针对含多级分支子馈线且分支线首端设有断路器保护的复杂配电网提出了一种可靠性评估算法。首先对网络进行两级简化处理,通过改进的网络等值法将向上的等效节点直接串接在分支开关下游,将上级网络对下级网络的影响视为向下展开所形成简单节点网络中的区域节点指标,在后续处理时再将该影响叠加到停电指标结果中,避免了传统网络等值可能带来的误差。随后导出了基于故障影响矩阵的指标计算方法,可快速计算出区域和负荷点的可靠性指标以及系统指标。算法考虑了各种开关故障和自动化开关拒动的影响,计算快速准确且易于编程实现。算例验证了算法的正确性和有效性。

Abstract: A new method is proposed for the reliability evaluation of complex distribution networks, which consists of multistage sub- feeders with breakers and protections installed. First, the complex distribution network is simplified into several simple node networks. The upward-equivalent node is connected to the branch switch directly in the improved network-equivalent method.The impact of the superior network on the lower network is treated as an area-node reliability index of the downward-equivalent simple node network,which is added to the reliability indexes in the subsequent computing process. The error of the traditional network-equivalent method is avoided in the improved method. Then a fast method based on the fault influence matrix is derived. The reliability indexes can be calculated using the proposed method. The effect of various switching devices on the system reliability is also taken into account during the computing process. It is not only as accurate as the FMEA method,but faster than the existing algorithms. Moreover, it is easy for programming. Test results are presented to illustrate the effectiveness of the algorithm.

Key words: power system, complex distribution networks, sub-feeders, reliability evaluation, network simplification, fault influence matrix, switch faults, automatic switch refusing to action
