In the gas industry the control of the compression system has two primary objectives: the operation of the machine and also its protection against damage such as that following a surge cycle. The interaction between these two control actions can be strong, causing instability and oscillations. Moreover whenever the gas is recycled for surge protection, it is not delivered as final product and energy...
Compressors operate in parallel to increase the supply of a gas in many applications in process industries (e.g. an air separation process). To optimally distribute the load of the compressors in parallel, an optimization problem is formulated that takes into account the operational constraints of the compressors and the objective is to reduce operational costs, i.e. power consumption of the drivers...
In this paper, a multivariate statistical projection method based on Principal Component Analysis (PCA) is proposed for detecting and extracting unusual or anomalous events from wide-area monitoring data. The method combines PCA with statistical test to detect and analyze anomalous dynamic events from measured data. Simulations based on a transient stability model of the New England Test System are...
