三相同步发电机有功功率调节的研究

Study on the regulation of active power for three-phase synchronous generator

三相同步发电机作为三相工业频率的交流电源 ,研究其有功功率调节具有重要意义 .讨论了欲保持无功功率不变 ,当调节有功功率时 ,功角δ和励磁电流If 随有功功率调节的变化关系 ,以及电枢电流 Ia 和空载电势 E0 的变化轨迹 .

It's significant to study the regulation of active power of three-phase synchronous generator by way of the alternating power source of three-phase industrial frequency. Accordingly, this paper has concluded a variable relation formula, ie, how power angle (δ) and excited electric current (Ι f) change with active power, and the changing-locus of armature electric current ( a) and weight empty electric potential ( a) as well under the condition of regulating active power with the changelessness of keeping unavailable power
