摘　　要：在分析Z型接地变压器原理的基础上,将其进行一定的简化,利用耦合元件建立基于EMTP的Z型接地变压器模型,并利用简化Z型接地变压器模型建立了10 kV电缆配电网系统仿真,仿真结果证明了该方法的有效性,该模拟方法为中性点接地系统正确仿真奠定了基础,补充了部分仿真软件的仿真模型。Simplification is made after analyzing the principles of Z-type grounding transformers, and Z-type grounding transformer model based on EMTP is set up by coupling element. And simulation of 10 kV cable distribution network is set up by the simplified Z- type grounding transformer model. The result shows the method is effective, which has laid a basis for a good simulation of neutral point grounding system, adding simulation model for partial software.
