Objetivo TO MAKE A WIND TURBINE ATTRACTIVE FOR COMMERCIAL ENERGY PRODUCTION IT IS NECESSARY TO DECREASE THE CONSTRUCTION COSTS AND INCREASE BOTH THE LIFE TIME AND ENERGY OUTPUT OF THE WIND TURBINE. IT IS POSSIBLE TO DECREASE THE TOTAL WIND TURBINE COST BY USING FLEXIBLE COMPONENTS. THE LIFE TIME AND ENERGY PRODUCTION OF A (FLEXIBLE) WIND TURBINE CAN BE INCREASED BY A WELL DESIGNED CONTROLLER. IN ORDER TO DESIGN A FLEXIBLE WIND TURBINE AND DESIGNING A CONTROLLER A DYNAMIC MODEL OF THE WIND TURBINE IS NECESSARY. THIS DYNAMIC MODEL MUST INCLUDE ALL RELEVANT DYNAMICS OF THE INDIVIDUAL COMPONENTS TOGETHER WITH THEIR INTERACTION. THE AIM OF THIS PROJECT IS TWOFOLD: - THE DEVELOPMENT OF AN INTEGRATED DYNAMIC MODEL OF A FLEXIBLE WIND TURBINE, WHICH ALSO CAN BE USED AS A TOOL TO DESIGN A WIND TURBINE. THIS MODEL MUST HAVE A MODULAR STRUCTURE, SO THAT DIFFERENT SUBMODELS CAN BE USED EASILY, (FOR EXAMPLE A SYNCHRONOUS GENERATOR WITH DC-LINK, A DC GENERATOR OR A DOUBLE FED SYNCHRONOUS GENERATOR) - TO DESIGN A CONTROLLER IN ORDER TO INCREASE THE LIFE TIME AND ENERGY PRODUCTION OF A FLEXIBLE WIND TURBINE. ONE OF THE POSSIBILITIES TO REDUCE THE COST OF ENERGY PRODUCED BY WIND TURBINES IS THE APPLICATION OF FLEXIBLE WIND TURBINES CONTROLLED BY HIGH QUALITY CONTROLLERS. FLEXIBLE WIND TURBINES ARE REALIZED WITH SOFT CHARACTERISITICS IN ALL THE SUBSYSTEMS IN ORDER TO REDUCE THE INTERNAL STRESSES, AND THEREBY ALLOWING THE APPLICATION OF LIGHTER AND LESS COSTLY COMPONENTS. HOWEVER A FLEXIBLE WIND TURBINE MUST BE DESIGNED CAREFULLY OTHERWISE THE ATTRACTIVE ASPECTS WILL BE LOST OR EVEN ACT REVERSED. IN AN EARLY STAGE OF THE WIND TURBINE DESIGN THE CONTROLLER DESIGN HAS TO BE INCORPORATED. WITH A WELL DESIGNED CONTROLLER IT IS POSSIBLE TO INFLUENCE THE CHARACTERISTICS OF THE COMPLETE WIND TURBINE SYSTEM. IN A PRIMARY DESIGN PHASE IT IS USEFUL TO SIMULATE THE DYNAMIC BEHAVIOUR OF THE DIFFERENT POSSIBLE WIND TURBINE CONFIGURATIONS (FOR EXAMPLE RIGID OR FLEXIBLE TOWER), UNDER DIFFERENT CONDITIONS (FOR EXAMPLE WIND GUSTS OR GRID DISTURBANCES), UNDER DIFFERENT CONTROL STRATEGIES (FOR EXAMPLE SINGLE LOOP OR MULTIVARIABLE CONTROLLERS) AND TO ANALYZE THE SYSTEM CHARACTERISTICS OF THE LINEARIZED WIND TURBINE. THE NEED OF COMPUTER CODE TO SIMULATE THE DYNAMIC BEHAVIOUR OF THE FLEXIBLE WIND TURBINE UNDER DESIGN IS OBVIOUS. THE COMPUTER CODE "INDYMO" IS DESIGNED TO MEET THE MENTIONED SPECIFICATIONS. DUE TO THE DEFINITION OF INTERACTION VARIABLES BETWEEN THE DIFFERENT PARTS OF THE WIND TURBINE IT IS POSSIBLE TO DERIVE MATHEMATICAL MODELS FOR EACH SUBSYSTEM (EG. GENERATOR OR TRANSMISSION). USING THE MODULAR STRUCTURE OF THE COMPUTER CODE IT IS POSSIBLE TO SIMULATE DIFFERENT WIND TURBINE CONFIGURATIONS IN AN EASY AND USER FRIENDLY WAY. THIS COMPUTER CODE IS WRITTEN IN ANSI FORTRAN 77, AND THUS ALLOWING THE APPLICATION ON DIFFERENT COMPUTERS LIKE A PC OR VAX COMPUTER SYSTEM. THE INPUT TO INDYMO AND ITS OUTPUT ARE FILES AND THEREBY THE PROGRAMME IS FLEXIBLE TO COOPERATE WITH AVAILABLE STANDARD PROGRAMMES.
