摘要
电力机车牵引负荷是牵引供电系统中的主要谐波源之一,谐波含量已经成为电力机车的一个重要电气性能指标。利用PSCAD/EMTDC仿真软件建立了SS6B型电力机车仿真模型。通过机车牵引控制特性函数与整流电路的关系确定导通角α,采用仿真软件内嵌的编程语言FORTRAN77编程实现了电力机车控制策略。通过对仿真波形与下庄变电所实测波形进行比较,验证了该仿真方法的有效性和可靠性。
Electrical locomotive traction load is the main source of harmonics in traction power system and harmonic content has become an important electrical performance index. This paper adopts the PSCAD / EMTDC simulation software to establish simulation model of the SS6B electrical locomotive. The paper determine the firing angle through the relationship between traction characteristics function and commutating circuit in the electrical locomotive. Using the simulation software embedded programming language FORTRAN77, this paper tries to realize the control strategy. The validity and reliability of this method can be verified by comparing simulation waveform with the measured waveform of Xiazhuang substation.
