【摘要】 为保证异步发电机空载时能够建立电压并稳定运行,必须选择合适的建压电容值,因此需要确定其空载最小建压电容。从异步发电机稳态运行的等值电路出发,根据异步发电机稳态运行时的回路阻抗为零选取合适的目标函数,利用变量轮换的直接优化方法计算空载最小建压电容值。此方法编程简单,收敛速度快计算准确度高。更多还原

【Abstract】 In order to build up a terminal voltage under no load steady-state operation for induction generator, an appropriate capacitance must be choosed, so it is necessary to determine the minimum capacitance under no load operation. Based on the steady-state equivalent circuit of induction generator, and by setting the loop impedance to be zero, the objective function is given. Using the variable-shifting method the minimum capacitance is calculated. It shows the advantages of easily programming, fast rate of convergence and high calculation accuracy.更多还原
