Abstract

The topic of this paper is to construct the module of the current transformer (CT) basing the Jiles-Atherton (J-A) hysteresis model in electromagnetic transient program (EMTP) and alternative transient program (ATP) simulation. The J-A hysteresis model constitutes of first-order ordinary differential equations and has five parameters that can be determined by measurements of hysteresis loop. According to the description of J-A hysteresis model, we can establish the CT module basing J-A hysteresis model using transient analysis of control systems (TACS) in EMTP. Compared with type 96's CT module with hysteresis characteristic, the simulated result of the CT module basing J-A hysteresis model is apparently different in fault transient situation. Therefore, this proposed CT module basing J-A hysteresis model has not only the analysis capability of the transient situation, but also the flexibility of different point of power circuit

EMTP/ATP仿真中基于Jiles-Atherton滞回模型的电流互感器模块
本文的课题是基于Jiles-Atherton (J-A)磁滞模型在电磁暂态程序(EMTP)和备选暂态程序(ATP)仿真中构建电流互感器(CT)模块。J-A型迟滞模型由一阶常微分方程构成,有五个参数,可通过测量迟滞回路来确定。根据J-A迟滞模型的描述,利用EMTP中的控制系统暂态分析(TACS),建立了基于J-A迟滞模型的CT模块。与96型带迟滞特性的CT模组相比,基于J-A迟滞模型的CT模组在故障暂态情况下的模拟结果有明显差异。因此,本文提出的基于J-A磁滞模型的CT模块不仅具有对暂态情况的分析能力,而且具有对电力电路不同点的灵活性
