摘要:
为了提高三相整流发电机电压控制精确度,提出采用直流侧电压负反馈和励磁电流负反馈构成的双闭环励磁控制策略。根据发电机空载特性曲线引入饱和系数,建立三相整流发电机励磁数学模型。该模型较好地反应出了其非线性特征。分析电压环采用PI调节存在突加负载时电压跌落较大的原因,给出将电流限幅器下限设置为空载励磁电流设定值的解决方法。为了验证所提出策略和分析方法的正确性,构建以DSP控制器为核心的整流发电机数字式励磁控制系统。实验结果表明采用双闭环控制的励磁系统具有较好的电压调节精确度,设置电流限幅器下限的方法明显改善了直流侧电压跌落。
Abstract:
For improving the accuracy of DC-link voltage regulation in the three-phase rectified generator,a double close loop control strategy with DC-link voltage close loop and the field current close loop is proposed for its excitation system.Based on the generator non-load saturation curve,the saturation effect coefficient was introduced to establish the mathematical model of the rectified generator.The corresponding nonlinear characteristic was pointed out from this model.With a voltage PI regulator,the principl...
