Effect of Unbalanced and Non-Linear Loads on Operation of the Turbogenerator of a Distributed Generation Unit

The article presents a description of models and results research on separate joint effects unbalanced non-linear loads the operation lower-power synchronous generator. modeling generator included automatic regulators excitation rotor speed. For our studies, we used computer built in MATLAB environment Fazonord package, as well physical model low-power simulation attested to occurrence following negative effects: there was noticeable sequence current, began emit higher harmonics into network, amplitude forced oscillations current increased. presence these can lead additional mechanical vibrations rotor, accelerated wear equipment, loss stability. To ensure that generators operate unbalance harmonic distortion, it is necessary limit their load. maximum phase difference, which must not exceed 12% nominal be criterion. Furthermore, when distributed generation units serve loads, implement special measures protect generating equipment: use direct links, filters, installation protections limiting limitation, etc.
