摘要:
准确的线损计算是分析线损构成、制定降损措施以实现电网经济运行的基础。配电网谐波污染日趋严重,因谐波因素导致配电网运行状态及设备参数发生较大变化,由此产生的附加损耗已不容忽视。本文在分析了传统线损计算方法的基础上,系统分析了谐波对配电变压器及线路损耗的影响机理,通过引入输电线路交流电阻系数和变压器谐波损耗因子,提出一种计及谐波因素的线损计算模型,并结合典型配电变压器及线路,完成谐波对其损耗影响的量化计算。最后通过建模仿真,验证了模型的有效性和准确性.
Abstract:
Accurate line loss calculation is the basis of realizing economic operation of power grid. The harmonic pollution in distribution network is becoming increasingly serious. Because of harmonic factors, the distribution network operation state and equipment parameters have changed greatly, and the additional losses arising therefrom have not been neglected. Based on the analysis of the traditional calculation method of line loss, this paper systematically analyzes the mechanism of harmonic effect on distribution transformer and power line. By introducing the transmission line AC resistance coefficient and transformer harmonic loss factors, a loss calculation model considering harmonic is put forward. Then, combined with the typical distribution transformer and transmission line, the harmonic loss was calculated quantitatively. Finally, the validity and accuracy of the model are verified by modeling and simulation.
