【摘要】：针对现有多谐波源责任分摊方法中存在的测量平差问题,对谐波责任稳健估计方法进行了研究。为了克服系统背景谐波电压波动的影响,提出基于复残差的背景谐波电压划分方法,引入中国科学院大地测量与地球物理研究所提出的IGG权重函数,基于复数域多元线性回归数学模型,在各时段内重复使用IGG权重函数确定回归系数,以提高背景谐波电压中样本筛选的抗差性;结合等效谐波阻抗的置信区间,提出了评估结果的检验方法;对IEEE 14节点测试系统进行仿真,仿真结果表明所提多谐波源责任分摊方法能够有效克服系统背景谐波电压波动的影响,并与现有分摊方法进行比较,验证所提方法的准确性和可行性。
[Abstract]:Aiming at the problem of measurement adjustment in the existing methods of multi-harmonic source responsibility allocation, the robust estimation method of harmonic responsibility is studied. In order to overcome the influence of background harmonic voltage fluctuation, a method of background harmonic voltage division based on complex residuals is proposed. The IGG weight function proposed by Institute of Geodesy and Geophysics of Chinese Academy of Sciences is introduced. Based on the multiple linear regression mathematical model in complex domain, IGG weight function is used repeatedly to determine the regression coefficient in each period of time to improve the robustness of sample selection in background harmonic voltage, and to combine the confidence interval of equivalent harmonic impedance. The simulation results of the IEEE 14-bus test system show that the proposed multi-harmonic source allocation method can effectively overcome the influence of the harmonic voltage fluctuation in the background of the system. The accuracy and feasibility of the proposed method are verified by comparing with the existing method.
