摘要
本文以一段定子铁心和一个通风道为研究对象,分析了定子铁心温升、绕组温升与发电机相电压、相电流、无功功率之间的状态方程。并根据此状态方程,推导出了定子绕组温升与发电机相电压、相电流、无功功率之间的传递函数,此传递函数即为定子绕组温升辨识模型。最后,通过实际试验验证了该模型的正确性,为发电机状态监测研究提供了基础。
This paper analyzes the equation of state of the stator core temperature, winding temperature rise and the generator phase voltage, phase current, reactive power, some of the stator core and a ventilation channel for the study. According to this equation of state, it deduces the transfer function between generator stator winding temperature rise and phase voltage, phase current, reactive power, which is the stator winding temperature rise of identification model. Finally, this paper verifies the accuracy of the model for subsequent generator study, which provides a platform for condition monitoring through the actual test.
