A Decision Tree Approach for Steam Turbine-Generator Fault Diagnosis
Redundancy and inconsistency are universal features of the turbine vibration fault diagnosis. If we can provide a solution to the problem, it should be very meaningful that the fault diagnosis data included redundant and inconsistent information could be used to decision-making rules of fault diagnosis. A novel data mining approach for fault diagnosis of turbine generator unit is proposed based...
متن کاملAnalysis and Design of a Permanent-Magnet Outer-Rotor Synchronous Generator for a Direct-Drive Vertical-Axis Wind Turbine
In Permanent-Magnet Synchronous Generators (PMSGs) the reduction of cogging torque is one of the most important problems in their performance and evaluation. In this paper, at first, a direct-drive vertical-axis wind turbine is chosen. According to its nominal value operational point, necessary parameters for the generator is extracted. Due to an analytical method, four generators with differen...
متن کاملThe Extension of an Application Shell For Turbine-Generator Diagnosis
As a variety of techniques and problem-solving methods become available for expert systems, practitioners need to understand how specific domain and task characteristics should influence the selection of methods. The diagnostic task domain varies with respect to many attributes. These include the amount and quality of data, degree of access to component failures, conclusiveness of test results,...
متن کاملResidual Generator Fuzzy Identification for Wind Turbine Benchmark Fault Diagnosis
In order to improve the availability of wind turbines, thus improving their efficiency, it is important to detect and isolate faults in their earlier occurrence. The main problem of model-based fault diagnosis applied to wind turbines is represented by the system complexity, as well as the reliability of the available measurements. In this work, a data-driven strategy relying on fuzzy models is...
متن کاملHarmony search method for optimal wind turbine electrical generator design
The Harmony Search (HS) method is an emerging meta-heuristic optimization algorithm, which has been employed to cope with numerous challenging tasks during the past decade. In this paper, the essential theory of the HS algorithm is first described in details. Next, a few typical variations of the HS method are explained. The application of the HS in a practical wind turbine electrical generator...
