The paper discusses some engineering aspects of the utilization of asynchronous generators in autonomous unconventional single or mixed energy systems: hydro, diesel, wind, and biogas. The authors have built several energy systems with asynchronous generators with variable speed and constant frequency, implemented in wind generator systems in Romania. They have constructed an energy system with constant capacity excited asynchronous generator at Sarata Microhydrostation, Fagaras Mountains (1450 m). In this system the voltage was controlled by varying the speed of the turbine. For systems with uncontrolled hydroturbines the authors investigated constant loaded asynchronous generator with constant capacitive excitation and dump load control. Additionally, they investigated a system based on constant speed asynchronous generator whose voltage is controlled by an original system with continuous variable capacitive excitation. The driving motor is a thermal motor supplied with biogas. The system was developed at the request of the National Institute for Thermal Motors (Bucharest, Romania). The authors present their original proposals for mixed hydro, diesel, wind, biogas energetical systems based on asynchronous generator utilization. Original system structures are presented for resistive loaded systems as well as for resistive-inductive loaded systems. They also present some original schematic diagrams, methods and algorithms for asynchronous generator characteristics calculation. These characteristics are useful in the design of the excitation system, allowing determination of the rated parameter values of its elements. Some examples of asynchronous generator operation characteristics, calculated with these methods, are given in the paper.
