Modeling and Control of 1.5 MW HESG-Based Wind Conversion System: Advanced Aerodynamic Modeling

Received: 11 January 2020 Accepted: 3 March 2020 Setting up an experimental test bench for a large-scale wind conversion system (WCS) could be very challenging in terms of cost, size and complexity of the electrical and mechanical components especially in an academic research environment. Therefore, the aim of this paper is to establish an alternative through the development of a realistic simulation model. Such a model is essential for a better performances’ assessment of the studied 1.5 MW aerogenerator, based on a Hybrid Excitation Synchronous Generator (HESG). A model of the WCS taking into account both complex electrical phenomena and aerodynamic behaviors is established using the code FAST. Two pitch controllers are proposed and investigated. The first one consists of a conventional PI regulator. As for the second one, it includes a PI-based fuzzy logic controller. The blades’ loads, the low-speed shaft (LSS) torque ripple and loads are also given. Simulations results have confirmed the efficiency of the implemented fuzzy logic pitch controller and the capabilities of the developed model in simulating the behaviors of the modeled WCS in different operating regions.
