摘　　要：为了解罗氏线圈的动态特性,基于分布参数模型研究了一种Rogowski线圈仿真的分裂算法。该法将Ro-gowski线圈等分成若干段,提出每段Rogowski线圈离散时间的等效动态电源模型和Rogowski线圈的离散时间电路模型。该模型在任意长时间内与Rogowski线圈等效,而非在一个积分步长内,这降低了仿真的计算量;描述此模型的参数具有明确的物理含义,不仅可以通过计算求得,也可以通过测量确定,且具有最简单的电路结构和数学描述,可方便地应用于电流互感器装置的仿真之中。提出的方法适用于对均匀和非均匀绕包的罗氏线圈进行高精度的仿真,且方法简单、计算量少,易于实现编程,为罗式线圈电流互感器的研制提供了有效的仿真手段。In order to find out the dynamic characteristic of the Rogowski coil, a new diakoptics-based algorithm for the simulation of Rogowski coil is presented based on the distributed parameters model. Rogowski coil is divided equally into some sections, and the discrete-time equivalent dynamic model is proposed for each of sections, whereby the discrete-time equivalent dynamic model is formed for the total Rogowski coil. This model is effective in any interval with the simplest circuit structure and mathematical formulation, and the parameters of this model can be calculated by mathematical equations or measured by experiments, with clear practical meanings. The proposed model is effective for the simulations of both symmetric and asymmetric Rogowski coil CT, and it can be easily implemented without intensive computations. Therefore, this paper provides an effective simulation tool for Rogowski coil CT＇s manufactures.
