SR motors are gaining wider popularity among variable-speed drives. This is due to their simple, low-cost construction characterized by an absence of magnets and rotor winding, high level of performance over a wide range of speeds, and fault-tolerant power stage design. Availability and the moderate cost of the necessary electronic components make SR drives a viable alternative to other commonl...
Quality control is applied in production process. The good condition of electrical machines can be obtained by using diagnostics. There are a lot of methods that can be used for diagnostics of electrical machines. In the literature, standard methods are based on a study of electrical signals. This project work start with a novel automated practical implementation for non contiguous rotor side b...
Bearingless switched reluctance motor (BSRM) has the advantages of high integration and low loss, is especially suitable for flywheel batteries. In order to enhance reliability fault tolerance ability BSRM, a novel dual-channel BSRM proposed in this paper. This combined merits magnetic bearing, can realize fault-tolerant operation. The scalloped rotor poles are evenly distributed on inner outer...
Active sensor fault tolerant output feedback tracking control for wind turbine systems via T-S model
This paper presents a new approach to active sensor fault tolerant tracking control (FTTC) for offshore wind turbine (OWT) described via Takagi–Sugeno (T–S) multiple models. The FTTC strategy is designed in such way that aims to maintain nominal wind turbine controller without any change in both fault and fault-free cases. This is achieved by inserting T–S proportional state estimators augmente...
Numerical magnetic field analysis and signal processing for fault diagnostics of electrical machines
Numerical magnetic field analysis is used for predicting the performance of an induction motor and a slip-ring generator having different faults implemented in their structure. Virtual measurement data provided by the numerical magnetic field analysis are analysed using modern signal processing techniques to get a reliable indication of the fault. Support vector machine based classification is ...
Abstract The bond graph and temporal causal (TCG) are proposed to diagnose the fault of three-phase asynchronous motors. model motor is constructed using general equations in coordinate system. analytical redundancy relationships (ARRs) signature matrix (FSM) derived systematically by introducing TCG improve system isolability. Simulation experiments conducted for rotor-turn short-circuit rotor...
In this article, a four-phase dual armature-winding wound-field doubly salient machine with distributed field magnetomotive forces (DAW-WFDSM-DF) and corresponding double-redundant rectifier circuit are proposed to improve the electromagnetic performance of traditional WFDSM in terms output voltage ripple, fault-tolerant capability capability. Firstly, due uniformly machine, more feasible stato...
as one of the most promising distributed generation (dg) sources, wind power technology has been widely developed in recent years. doubly fed induction generator (dfig) is currently employed as one of the most common topologies for wind turbine generators (wtgs). this generator operates as a synchronous/asynchronous hybrid generators. therefore, it is necessary to power engineers find understan...
