社会的持续增长和发展与满足其需求所需的能源数量直接相关。因此，需要现有电网的更多互连，增加了其操作的复杂性。因此，较大的电力系统容易经历区域间振荡，这是由来自不同地理位置的发电机相互振荡触发的。无论这些所谓的区域间振荡是否未受抑制，它们最终都可能导致系统崩溃。在这项工作中，线性二次高斯（LQG）控制方法阻尼区域间的振荡，这是一个动态特征系统实现算法（ERA）耦合，提出。虽然这两个概念是有据可查的文献中，新颖之处是它的组合产生的快速和有效的阻尼控制器。该架构是作为一个数字电力系统稳定器（PSS）使用专业软件DigSilent PowerFactory和Matlab的组合。所提出的控制器通过IEEE基准新英格兰模型的动态系统仿真进行了验证。此外，一个教程，以实现所提出的控制器。
The continuous growth and development of society have a direct correlation to the amount of energy required to satisfy its demand. As consequence, more interconnections of existing electrical networks are required, increasing the complexity on its operation. Thus, larger power systems are prone to experience inter-area oscillations, which are triggered by generators oscillating against each other from different geographic locations. Whether these so called inter-area oscillations are undamped, they could eventually lead to a system collapse. In this work, a Linear Quadratic Gaussian (LQG) control approach to damp inter-area oscillations out, which is coupled with a dynamic eigensystem realization algorithm (ERA), is proposed. Although these two concepts are well documented on the literature, the novelty presented here is its combination resulting on a fast and effective damping controller. The proposed architecture is implemented as a digital Power System Stabilizer (PSS) using the combination of the professional softwares DigSilent PowerFactory and Matlab. The presented controller is validated trough dynamic system simulations on the IEEE benchmark New England model. Additionally, a tutorial to implement the proposed controller is also presented.
