摘要
常用电磁暂态分析软件,如ATP-EMTP,PSpice等,具有多种电力元件模型,部分还具有传输线的分布参数模型,然而,它们都不能直接研究场-线耦合问题,而场-线耦合传输线模型能完成这项工作,但是无法利用现有电磁暂态软件直接实现它们,Taylor模型是其中常用的一种。为了利用内含分布参数传输线模型的电磁暂态分析软件实现Taylor模型,基于电路理论推导了Taylor模型新型等效电路,使之符合ATP-EMTP等电磁暂态分析软件的分布参数传输线建模特点。分别利用ATP-EMTP软件基于所推导的Taylor模型等效电路,以及Matlab软件基于Fourier变换和逆变换方法,对算例给出的传输线耦合外场的电磁暂态响应进行了计算,结果表明2种方法计算结果较符合,证明所推导的Taylor模型等效电路是正确的,可以利用电磁暂态软件ATP-EMTP对其进行建模。该研究结果的应用可降低场-线耦合研究的复杂度。
The commonly used electromagnetic transient programs(ETP), such as ATP-EMTP, PSpice, etc, can not solve field-to-wire coupling problems, wheras, the field-to-wire coupling models, like the Taylor model, cannot be implemented by the common available ETP softwares. In order to implement the Taylor model in ETP software, we proposed a new equivalent circuit of Taylor model based on electric circuit theory, and calculated the transient response of a transmission line coupling with external field by ATP-EMTP based on the new equivalent circuit of Taylor model and software Matlab based on Fourier and inverse-Fourier transform methods, respectively, and calculation results of the two ways coincide well with each other, showing that the new equivalent circuit of Taylor model is right and is able to be implemented by ATP-EMTP, and can reduce the complexity of field-to-wire coupling research.
