考虑负荷分类的低压台区线损率计算方法

Calculation Method of Line Loss Rate in Low Voltage Substation Considering Load Classification

为降低低压台区线损率出现的目标误差,营造稳定、安全的线损处理环境,设计了一种考虑负荷分类状态的低压台区线损率计算方法。选取有源低压台区线损影响因子,在标定的范围之内,设计线损多负荷归一计算流程,执行线损小波神经网络(Wavelet Neural Network,WNN)负荷分类环境,构建线损计算模型,采用K-Means负荷聚类法实现线损率计算。测试结果表明:所设计的负荷分类台区线损计算方法得出的线损目标误差均可控制在1.5%以下,表明此种计算方法的误差小,覆盖范围更为广泛,具有实际的应用价值。

In order to reduce the target error of line loss rate in low-voltage substation area and create a stable and safe line loss processing environment,a calculation method of line loss rate in low-voltage substation area considering load classification is designed in this paper.Select the line loss influence factor in the active low-voltage substation area,design the line loss multi load normalization calculation process within the calibration range,implement the line loss Wavelet Neural Network(WNN)load classification environment,build the line loss calculation model,and use the K-means load clustering method to calculate the line loss rate.The test results show that the line loss target error obtained by the load classification substation line loss calculation method designed in this paper can be controlled below 1.5%,which shows that this calculation method has small error,wider coverage and practical application value.
