三相不平衡度的线损算法改进研究

Study on Improvement of Line Loss Algorithm for Three-phase Unevenness

在三相负荷不平衡区域,传统线损计算方法的计算值和实际值会存在很大偏差。针对此问题研究了三相负荷不平衡的线损改进算法,结合不平衡度算法与等效电阻法,得出三相不平衡下线损增量公式。最后,在实际案例下计算不平衡度和线损增量,结果表明,与传统的线损算法相比,该算法更接近实际线损。

In the area of unbalanced three-phase load,there will be a great deviation between the calculated value and the actual value of the traditional line loss calculation method.In this paper,the three-phase unbalanced line loss improvement algorithm is studied for the above problems.According to the combination of the unbalanced degree algorithm and the equivalent resistance method,the formula of the loss increment of the three-phase unbalanced line is obtained.Finally,the unbalanced degree and line loss increment are calculated in the actual case,and the results show that the algorithm is closer to the actual line loss than the traditional line loss algorithm.
