摘要
在电力系统不平衡负荷不断增多的过程中,三相不平衡问题持续恶化,其导致的损耗电量是线损计算所需考量的重要因素,要得到准确的计算结果,必须确保数据的完整性。从三相不平衡角度出发,根据三相负荷大小对三相不平衡情况进行分类,针对计算过程中数据偏少的问题,运用对抗生成网络增加样本数据,进行不平衡度计算,利用不平衡度推出线损增量系数,得到“三相不平衡度-线损增量系数”的量化关系。通过使用对抗生成网络前后的平行试验对比发现,运用对抗生成网络可以有效提高计算精度,构建的“三相不平衡度-线损增量系数”的量化关系具有现实意义。
With the increasing diversification of unbalanced load in power system,the phenomenon of three-phase imbalance is becoming more and more serious.The loss of electricity is an important factor in line loss calculation.To obtain accurate results,data integrity must be ensured.From the point of view of three-phase imbalance,the three-phase imbalance is classified according to the size of three-phase load.In view of the problem of less data in the calculation process,the sample data is increased by confrontation generation network,and the imbalance degree is calculated.The nonlinear model of“three-phase imbalance-line loss increment coefficient”is obtained by using imbalance degree.Through the comparison of parallel experiments before and after confrontation generation network,it is found that the confrontation generation network can effectively improve the calculation accuracy,and the nonlinear model of“three-phase unevenness-line loss increment coefficient”is of practical significance.
