Development of mathematical models of energy conversion processes in an induction motor supplied from an autonomous induction generator with parametric non-symmetry

The paper presents studies of the system "induction generator-induction motor" with parametric asymmetry on a mathematical model to determine quality generated electricity in load operating modes. A has been developed taking into account losses steel and asymmetry. analysis transient characteristics an induction generator when motor is connected symmetrical asymmetrical modes operation carried out. results changes main at various degrees are presented. was analyzed based calculations unbalance coefficients for each assessment thermal state steady-state conditions out using equivalent circuit. Thermal transients were investigated starting from autonomous energy source generator. On model, study effect output voltage heating It shown that reaches 3–10 % causes overheating windings excess permissible values. regression studying powered by stator windings. use obtained equations will make it possible most rational combination factors affecting machines, which they not overheat above maximum temperature values corresponding insulation classes
