摘要
现有的感应子脉冲发电机容性整流系统平均值模型忽略了电枢绕组电阻的影响,可能导致仿真结果存在较大误差。本文在计算换流角度和平均电流以及状态方程中均考虑了电枢绕组电阻的影响,并对比分析了电枢绕组电阻影响的不同考虑方式下的仿真误差,还分析了电阻值大小和仿真误差大小之间的关系。研究结果表明,在换流角度和平均电流计算、状态方程中均考虑电枢绕组电阻时,仿真误差最小;仅在换流角度和平均电流计算中考虑电枢绕组电阻影响时误差最大;在换流角度和平均电流计算中忽略电枢绕组电阻影响会使充电电流仿真值偏小,而在状态方程中忽略电枢绕组电阻影响会使得充电电流仿真值偏大。电阻值越大,则仿真误差越大。最后通过实验验证了本论文的结论。对于样机系统,考虑电枢绕组电阻影响可以使得充电电压和充电所需时间的仿真结果的误差大幅降低。
The existing average-value model for pulsed capacitor charging power supply based on homopolar inductor alternator(HIA)neglects influence of the armature winding resistance,which may lead to a large error in the simulation results.Considering the influence of armature winding resistance in the calculation of commutation angle and average current,as well as in the state equation,and the simulation error of armature winding resistance under different consideration was analyzed and compared,and the relationship between the resistance value and the simulation error was also analyzed.The results show that the simulation error is minimum when the resistance of armature winding is considered in the calculation of commutation angle,average current and state equation,considering the influence of armature winding resistance only in the calculation of commutation angle and average current,the error is the biggest,and neglecting the influence of armature winding resistance in the calculation of commutation angle and average current will make the simulation value of charging current smaller,but neglecting the influence of armature winding resistance in the state equation will make the simulation value of charging current larger.The higher the resistance value is,the greater the simulation error is.Finally,the conclusion was verified by experiment.For the prototype system,when considering influence of armature winding resistance,the simulation error of the average model of charging voltage and charging time decrease dramatically.
