摘要:
 针对电力作动器类恒功率负载引起的负阻抗效应,提出采用负阻抗补偿法来解决电力作动
器系统的稳定性问题,并且进行补偿器设计方法的研究。首先通过推导电网输入导纳得出稳定判
据。然后比较常用增大电容法与负阻抗补偿法,分析两种方法对电能品质的影响及稳定性问题,并
比较补偿器参数的改变对干扰性能的影响,重点分析比例系数对电网性能的影响。再通过仿真和
实验对带有补偿器的作动器系统进行系统性能的验证。结论表明改进型负阻抗补偿法可以在满足
系统快速性的同时,采用相对小的电容来保证系统的稳定性。另一方面负阻抗补偿法对大扰动问
题仍然适用,同样可以改善电能品质。
Abstract:
 The negative input-resistance compensator is proposed to solve the stability problem caused by
constant power load as electromechanical acturator. Input admittance was derived to obtain stability conditions
first. Comparisons between the selecting large capacitor and adding negative input-resistance compensator
were done. The impact on the power quality and stability were analyzed for the two methods.
Simulations and experiments of the actuator system with compensator were adopted to verify the performance.
The conclusion indicates that the negative input-resistance compensator system realizes system stability
with relatively small capacitor as well as satisfies quick requirement. At the same time,the proposed
method could also be applied for large disturbance problem to modify the power quality.
