Add to ORKGRenewable and dispersed electrical generators can be divided into systems directly coupled to the grid, or systems which use power electronic converters for grid connection. A lot of generation is still done by an induction machine directly coupled to the grid, for example in micro combined heat power or small wind turbines. For asynchronous generators directly coupled to the grid, the voltage distortion can have a significant influence on the efficiency of the machine. A lot of papers discuss the influence of voltage harmonics on Induction Machines. The influence of voltage harmonics on Induction Generators is less researched. Although some research has been performed through simulation, due to difficult laboratory setup not many practical...
