Abstract

Despite the relatively low power generators and cogeneration plants they work in parallel with the network, the power of which can exceed the capacity of the machine, there are a number of problems associated with the redistribution of energy flows in the resulting pattern when unbalanced load. This redistribution, as shown in the work, resulting in a change of quality indicators of the functioning of the generator and the electrical system. Based on the analysis of the known methods to repel saturation processes steel magnetic synchronous machine system, using the theory of electrical machines, developed a model of a synchronous generator, taking into account the load unbalance. The package of visual programming simulated power system of small industrial enterprises, in which the composition is used synchronous generator. A series of experiments with simulation of the synchronous generator, taking into account the saturation of steel, a load in parallel with a comprehensive network and autonomously. As a result of analysis of time dependencies mode settings established the influence of asymmetry on the dynamic performance mode parameters and observed a significant impact of asymmetry in parallel operation with the power supply system. The results can be used in the construction of the drive control system of the machine under load unbalance.
