摘要
当输变电网络承载负荷超出额定值时,易导致设备损坏,威胁电力网络安全,为使电力网络能够掌握输变电负荷情况,提出了基于信息重构和DBSCAN算法的输变电负荷数据识别方法。定义电力负荷信息重构原则,并联合DBSCAN算法模型,完善电网架构体系,实现对输变电网络的重构。分别确定电压、电流、电力信号负荷三类电力参量的等级标准,实现对变电负荷数据的针对性识别。实验结果表明,该方法能够根据功率与电感数值,准确计算出电力网络的实时电量负荷水平,保障了输变电负荷数据的识别准确性。
When the load carried by the power transmission and transformation network exceeds the rated load,it will cause equipment damage and affect the safety of the power network.In order to enable the power network to grasp the load situation of power transmission and transformation,an information reconstruction and DBSCAN algorithm based data recognition method for power transmission and transformation load is proposed.Define the principle of power load information reconstruction,and combine it with the DBSCAN algorithm model to improve the power grid architecture system and achieve the reconstruction of the transmission and transformation network.Determine the level standards for voltage,current,and electrical signal load,respectively,to achieve targeted identification of substation load data.The experimental results show that this method can accurately calculate the real⁃time electricity load level of the power network based on power and inductance values,ensuring the accuracy of identifying transmission and transformation load data.
