摘要:为建立谐波励磁同步发电机(HESG)的非线性仿射模型,根据谐波绕组的结构特点,基于同步发电机电枢双反应理论,推导了三次谐波电势公式。结合转子运动方程、功率方程、励磁绕组电磁方程,得到了HESG的非线性仿射模型方程。基于军用电站的具体参数和相同的励磁调压系统参数,进行了仿真验证,结果表明:在突加额定负载的情况下,相对于传统结构的同步发电机,在向武器装备供电时,HESG的端电压振荡次数少,恢复稳定的时间短,功角变化迅速,更容易满足GJB1488对军用电站供电指标的要求。 关键词:谐波励磁;谐波电机模型;非线性仿射;谐波电势;三次谐波
Abstract: To establish the harmonic excitation synchronous generator non-affine nonlinear model, according to the structure and the character of the harmonic winding, based on the BLONDEL theory, the harmonic winding EMF formula was deduced. According to the motional equation, the power equation, the exciting coil electromagnetic equation, the HESG nonaffine nonlinear model was created. Based on the actual parameters of the military moving power station, the simulative analysis had been conducted. The result shows that the HESG has a rapid recovery of the teminal voltage. The terminal voltage index of the HESG could easily meet the national standared of GJB 1448. Key words: harmonic excitation; harmonic excitation synchronous generator model; non-affine model; harmonic potential; the third harmonic
