| 摘 要： | 提出了一种多机电力系统稳定器(PSS)参数协调优化的共轭梯度法.该方法以系统动态组合泛函作为评价PSS阻尼效果的性能指标,通过变分法处理组合泛函指标中的积分项,提出了采用轨迹逆积分技术计算该指标对PSS参数向量梯度的新方法.该方法以上述组合泛函指标最小作为PSS参数优化模型中的目标函数.由于目标函数考虑了电力系统大扰动...

| Abstract: | Proposed in this paper is a new conjugate gradient approach for the coordination of the power system stabilizer(PSS) parameter optimization of multi-machine power system.In this approach,combination functional index is introduced as a performance index to evaluate the damping effect of PSS,the integral term of the index is dealt with by means of the variational method,and a backward trajectory integration approach is put forward to calculate the gradient of the index to the PSS parameter vector.Moreover,min... |
