【摘要】：配电线路是配电网系统重要的元件,在尽量满足分布特性的情况下,将其集总实物化是构建配电网动态模拟平台的关键环节。以Π型线路模型为基础,提出配电线路等效模型实物化方法。所提模型涵盖了线路电阻、相间电容、对地电容及线路间自感和互感;在分析各种电感模型的优缺点后,提出了空心螺线环形结构,不仅可以抗电感饱和,还可将磁通封闭在线圈内部,抑制磁场泄漏。最后通过实验对线路模型的磁场封闭性和暂态变化特性进行验证,表明所提模型可用于模拟真实配电网线路。
[Abstract]:Distribution line is an important component of distribution network system. Under the condition of satisfying the distribution characteristics as far as possible, it is the key link to construct the dynamic simulation platform of distribution network. The physical method of equivalent model of distribution line is proposed. The model includes line resistance, interphase capacitance, ground capacitance, self-inductance and mutual inductance between lines. After analyzing the advantages and disadvantages of various inductance models, the hollow spiral ring structure is proposed. It can not only resist the inductance saturation, but also seal the magnetic flux inside the coil to suppress the leakage of the magnetic field. Finally, the magnetic field closure and transient characteristics of the circuit model are verified by experiments. It is shown that the proposed model can be used to simulate the real distribution network.
