Switched Reluctance Generator for Wind Power Applications
Green house effect has becomes a serious concern in many countries due to the increase consumption of the fossil fuel. There have been many studies to find an alternative power source. Wind energy found to be one of the most useful solutions to help in overcoming the air pollution and global. There is no agreed solution to conversion of wind energy to electrical energy. In this paper, the advan...
متن کاملControl of Switched Reluctance Generator for Wind Energy Applications
This paper discusses how the switched reluctance generator (SRG) converts mechanical energy from wind via turbine into electrical energy as directed by an electronic controller. Starting with a review of the electromechanical energy conversion principles, the paper examines the implications of the energy conversion process on how the SRG is controlled. The structure of the SRG controller for sp...
متن کاملStudy on switched reluctance generator.
The linear and non-linear math models of the switched reluctance generator (SRG) in generator mode were established in this work. The phase current and energy conversion process during generator operation were simulated by the linear math model. The non-linear math model was used to analyze the characteristics of the SRG operation in self-excitation mode and in separately-excitation mode. Some ...
متن کاملAn Accurate Position Estimation Method for Switched Reluctance Motor Drive
In this paper a low-cost sensorless control strategy of SR motor is proposed. The static flux-linkage characteristics of the motor are used for estimating the position. A number of discrepancies between the static and the dynamic characteristics of the motor are explained. In this paper the issues regarding eddy effects and mutual inductances in both static and dynamic conditions, and their inf...
متن کاملFault Diagnosis and Fault-tolerant Control of Position Sensors for Switched Reluctance Motors
Position sensor is the key of exact commutation for switched reluctance motor (SRM). When position sensor is faulted, some phase information of commutation will be lost, causes torque decrease, affects the system reliability. Through the analysis of the fault position signals, a real-time diagnostic method that detected the edge sequences of position signals and calculated the angle between the...
