摘要
在倍极感应励磁同步发电机中,转子励磁绕组中的励磁电流是由定于直流绕组建立的倍极磁场感应产生。转子励磁电流与定于直流绕组电流之间的关系是其重要电磁关系,通常用绕组电感参数表达,但由于该类电机结构的特殊性,有关电感参数的计算十分困难。本文从电感系数的基本定义出发,提出了一种有关电感系数的等效计算方法,并由此得出了用绕组参数表达的转子励磁电流实用计算公式,其正确性得到了实验验证。
In double-pole induced-excitation synchronous generator, the magnetizing current in the rotor winding is induced by the double-pole megnetic field in a DC winding on the stator. The relationship between the rotor field current and the current in the stator DC winding is very important and usually expressed by the inductance parameters.However, because of the special configuration, the calculations of these inductances are difficult. In this paper, an equivalent method of calculating these inductances is proposed. Based on this, an available calculating formula of the rotor field current is obtained, which is expressed by winding parameters. The effectiveness of the method and the formula is discussed and verified by tests.
