Abstract

Based on the assessment of the characteristics of some wind zones in Ukraine [1] and used abroad the wind speed in the design of windgenerators, the paper provides comparison of the main parameters of wind generators. According to a certain algorithm [4–9], a number of synchronous generators with a capacity of 600 to 3600 kW were calculated with a reference to the power of machines manufactured by the Large Electric Machine Plant (Kakhovka). The design presented in the paper [2] was taken as a basic design, which has not a case. The yoke of the stator plays role of the case. The stator with winding plays role of a module of the head of a wind turbine, that allows to reduce its weight and dimensions.

At the present time asynchronous generators with gears have been most widely used for increasing the speed, because the rotation speed of wind wheel decrease with power increase and is only a few revolutions per minute. With increasing speed, the electromagnetic torque, volume and mass of the generator decrease, but the corresponding parameters of the multiplier increase. In recent years, there has been a tendency to use gearless synchronous generators with permanent magnet excitation, which simplifies the design of the unit, improves the reliability of the installation, eliminates the need for maintenance of the gearbox (multiplier) and excitation losses. In this regard, the work compares these options for the implementation of the modular part of wind turbines in terms of electromagnetic parameters, mass and dimensions.

A change in the geometric relationships of the generator determines its electromagnetic parameters, therefore, the optimum ratios of the diameters of the stator and the rotor, the width of the slot and the tooth are determined, the dependence of the geometry of the tooth zone and power on the accepted number of slot per pole and phase (q) is determined; the possibility of using a “meander” winding due to the small calculated value of the number of turns in the section is substantiated. Such a winding allows to simplify the technology of its manufacture, gives the possibility of increasing the fill factor of the slot and power. Ref. 9, fig. 3.
