| 摘 要： | 电力变压器是输变电网络的主要设备。对上一级供电电源,因变压器自身特性和二次侧所驱动不同类型负载,电力变压器会产生谐波,是电网系统的谐波源。本文以电力变压器为研究对象,首先根据电力变压器的磁化特性,建立其谐波模型;其次在Matlab/Simulink环境下完成空载、驱动线性负载和非线性考察一次侧谐波产生情况,并获得重要结论。该文为谐波分析和谐波治理研究人员提供重要参考依据。

| Abstract: | The power transformer is the main equipment in the power transmission network. However,the power transformer will produce harmonic for the upper level power supply due to its own characteristics and driving different types of load,which means that the power transformer is also a power system harmonic source. As the research object in this paper,firstly the harmonic model is established according to the magnetization characteristic of power transformer. Secondly,the harmonic components produced in the power transformer are investigated when the transformer drives different types of load such as linear or nonlinear load in Matlab / Simulink environment and the important conclusion is obtained.This paper provides important value for harmonic analysis and harmonic governance researchers. |
