Short description of project
In this project the operation of wind turbines is investigated to identify possible fault indicators based only on the sensors already available in the power inverter. The research covers the whole electrical power conversion process: from the control algorithms for optimal adaptation to dynamic changing wind speeds to considerations on how the system energy efficiency is reduced by emerging fault conditions of different components and to a practical verification of the detection system on a reduced scale generator system. In the past years renewable energy sources like wind energy have gained much attention due to global warming and the scheduled reduction of CO2 emissions. To keep the efficiency of the energy conversion process of wind turbines at or near its optimum value all system components have to be continuously monitored. The most critical and vulnerable components are the gearbox as well as different generator components like windings or bearings. On-line fault detection of inverter controlled generators and mechanical components are usually based on special sensor systems and evaluation instruments which makes these systems expensive and thus usually not profitable in wind turbines. The classical approaches of online condition monitoring methods like current signature analysis are not applicable as the dynamic operation, pulse width modulation and the switching transients of the power electronics devices add additional harmonics and measurement noise to all sensor signals. 
Short description of the task performed by Croatian partner
