摘要

变压器是电力系统中最敏感、最复杂的元件之一。目前,仿真是对该元件进行性能分析的一种常用而有效的方法。本文的主要目的是对电力变压器的保护进行研究。本文提出了一种基于自互感的变压器模型。此外,还对230/ 63kv、125 MVA两绕组三腿铁芯变压器进行了仿真。仿真研究结果与试验数据进行了比较。计算结果证实了所提出方法的有效性

Transformer winding detailed modeling for protection studies
Transformer is one of the most sensitive and complex elements of a power system. Nowadays, simulation is a common and effective way for behavior analysis of this element. The main objective in this paper is protective studies of power transformer. In this study a transformer model based on the self and mutual inductances has been proposed. Also a 230/63 kV, 125 MVA transformer with two-winding and three-legged core has been simulated. Obtained simulation studies are compared with test data. Obtained results confirm validity of the developed method
