Robust fault estimation for wind turbine energy via hybrid systems

Abstract: The rapid development of modern wind turbine technology has led to increase demand for improving system reliability and practical concern for robust fault monitoring scheme. This paper presents the investigation of a 5MW Dynamic Wind Turbine Energy System that was designed to sustain condition monitoring and fault diagnosis with the goal of improving the reliability operations of universal practical control systems. A hybrid stochastic technique is proposed based on an augmented observer combined with eigenstr… Show more

“…It gives a design of the gain observer by using the left and right eigenstructure methods and aims to cancel directly the disturbance (for more details, see (Xu & Tseng 2007)). Recently, diagnostic observers are used in many applications in order to diagnosis damage (see, e.g., (Odofin et al 2016), (Sen & Bhattacharya 2017) and (Odofin et al 2018)). Residual generation using unknown input observer is a important diagnostic method and applied specially to isolate the fault.…”

“…Recent research carried out in this field identified two main approaches of FDI: signal‐based FDI and model‐based FDI. With the advancement in the field of digital computers and system identification, model‐based FDI has emerged as a powerful approach [10–12]. The model‐based approach depends on the mathematical model, which could cause false alarm between the actual system and model, which makes FDI dormant in most cases.…”

“…The literature review also shows some successful studies in predicting faults caused by complex nonlinearity reasons using operational SCADA data combined with diverse approaches such as adaptive neuron-fuzzy interference systems (ANFIS), Bayesian Networks and Deep Learning Networks [7][8][9]. A hybrid stochastic technique is proposed in reference [10], which is based on an augmented observer combined with Eigen structure assignment for the parameterization and the genetic algorithm (GA) optimization to address the attenuation of uncertainty mostly generated by disturbances. Data mining techniques are also applied to this data combination to model the power curve [11].…”
