Electrical disturbance generators are basically controlled voltage sources that can be used to emulate various electrical disturbances; they are used mainly for the purpose of investigating the behavior of electrical equipment under power related faults. This paper presents a novel topology for an electrical disturbances generator that uses a back to back voltage source inverter controlled by a repetitive...
Currently, there are several power converter topologies applied to wind power generation. The converters allow the use of wind turbines operating at variable speed, enabling better use of wind forces. The high performance of the converters is being increasingly demanded, mainly because of the increase in the power generation capacity by wind turbines, which gave rise to various converter topologies,...
The detection of disturbances in electrical power systems must be as fast as possible to avoid serious consequences. The occurrence of sags, particularly in Wind Electrical Synchronous Generators, may cause failures or even the destruction of the generator. This paper presents a comparison between a FPGA and a DSP system for Voltage Sags detection. The use of Field Programmable Gate Arrays (FPGAs)...
