摘要
针对利用聚类技术计算月度网损时,计算时间阶段划分过多和计算量过大的问题,首先根据月度网架结构与运行方式的变化情况,提出一种基于拓扑辨识分析的网损聚类计算时间阶段划分方法;其次,在对负荷精确性分析的基础上,提出一种基于融合理论的断面数量削减方法,在提高采集频率的情况下保证计算的速度;最后,提出月度网损计算的具体步骤。MATLAB仿真结果验证了所提方法的有效性。
Aiming at the too many time divisions and too large load of clustering technology in the monthly transmission loss calculation,a time partitioning method based on the topology identification and analysis is proposed for transmission loss according to the monthly change of network structure and operating mode. A cross section number reduction method based on the fusion theory and the accurate load analysis is proposed to increase the sampling frequency while ensure the calculation speed. The concrete steps of monthly transmission loss calculation are proposed. The simulative results of MATLAB verify the effectiveness of the proposed method.
