基于大数据的城市低压配电网运行可靠性评估

Reliability Evaluation of Urban Low Voltage Distribution Network Based on Big Data

传统城市低压配电网运行可靠性评估技术的可靠性较低,因此提出基于大数据的城市低压配电网运行可靠性评估算法。将评估指标设置为四项,作为后续参数和求取目标。根据馈线容许最大负荷容量,计算低压配电网转供容量,实现整体性评估城市低压配电网运行可靠性。实验数据表明,这种评估方法可提高配电网运行评估准确率约21%。

The reliability evaluation technology of traditional urban low-voltage distribution network operation reliability evaluation is low. To this end,the reliability evaluation algorithm of urban low-voltage distribution network for big data is proposed. The evaluation index is set to four items,as the subsequent parameters and the target of the calculation,according to the maximum allowable load capacity of the feeder,the conversion capacity of the low-voltage distribution network is calculated,and the overall evaluation of the operational reliability of the urban low-voltage distribution network is realized.The experimental data shows that the application design evaluation method can effectively improve the distribution network operation and can consider the evaluation accuracy increase by 21%.
