摘要
采用H∞优化算法来实现电力系统稳定器(PSS)的鲁棒控制设计。该方法采用了分子—分母双扰动表达形式、部分极点配置技术和一种新的加权函数选择方法,从而克服了某些传统PSS设计方法中受到的限制。在将电力系统的高度非线性特性作为模型的“不确定性”处理后,设计出的控制器具有很好的鲁棒性。与传统设计方法的比较,证实了所设计的PSS在较宽的系统运行范围内具有更好的阻尼性能。
The paper presents a robust PSS design approach based on H∞ method. The method uses the numerator-denominator perturbation representation and includes the partial pole placement technique and a new weighting function selection method. This overcomes certain conventional H∞ PSS design algorithm limitations. A robust PSS has been successfully designed by treating the highly non-linear characteristic of the power system as 'uncertainty' of the model. The design is verified to have better performance for a wide range of system operating conditions when compared with the conventional PSS design.
