The causes of technological errors are quite numerous and varied, and they can be classified according to various criteria, for example, by the type of technological operations (errors in the machining operation of parts, winding and laying the windings into stator’s slots, etc.). The program performs an automated calculation of the characteristics of the generator when the input dimensional parameters of the core change within the limits of the tolerance field for each of them set by the technical specifications (TS). The algorithm of the program is based on the method of calculating a three-phase synchronous generator with a cranked rotor. To assess this effect, a system of interconnected computer programs and mathematical models has been built, with which it is possible to determine the weight of the influence of technological deviations in the manufacture of the generator on its performance and the characteristics of the electrical system as a whole. Reducing the variation of the generator reliability indicators can be achieved by phased assessment and timely adjustment of the quality level of design, production and ensuring their connection with the quality management system.
