摘要 提出了一种提高基于阻尼补偿的直流(DC)发电机带恒功率负载(CPL)系统稳定性的方法。依据输入滤波器输出阻抗极大值最小原则对基于阻尼补偿的直流发电机带恒功率负载系统输入滤波器参数进行了最优设计,给出了设计方法和流程。运用Bode图和Nyquist曲线对基于阻尼补偿的直流发电机带恒功率负载系统进行稳定性分析,并与在输出端并联单电容的直流发电机带恒功率负载系统进行比较。对两种系统进行了仿真分析和试验验证。结果表明,基于阻尼补偿的直流发电机带恒功率负载系统较之在输出端并联单电容的直流发电机带恒功率负载系统带载能力可提高一倍以上。 A method is proposed to enhance the stability of a system with a direct current（DC） generator driving constant power load（CPL） based on damping compensation.Optimal design for input filter parameters in the system is accomplished to obtain the minimization of peak output impedance,and the design process is discussed in detail.By means of the Bode plot and Nyquist contour,stability analysis is carried out on two systems with DC generators driving CPL,one based on damping compensation and the other on only one capacitor.Simulations and experiments for both systems are used to validate the theoretical analysis.The results indicate that the capacity of a DC generator driving CPL is enhanced by more than 100% for the system based on damping compensation as compared with the system with only one capacitor.
