ОСОБЕННОСТИ ПРОЕКТИРОВАНИЯ ВЕТРОГЕНЕРАТОРОВ ПОВЫШЕННОЙ МОЩНОСТИ (600÷3600) кВт С ВОЗБУЖДЕНИЕМ ОТ ПОСТОЯННЫХ МАГНИТОВ |
| description |
The paper is based on the results of calculations of a number of synchronous gearless direct-drive wind generators of modular design [1] with permanent magnet excitation in range of power since 600 to 3600 kW at a wind speed that is taken abroad during the design – 12.5 m/s. This approach to the study of machines allows to evaluate the complex relationship of their parameters with a minimum of assumptions, in particular, to take into account the saturation of the most loaded sections of the magnetic circuit and determine the feasibility of using some possible winding options that provide the greatest electromagnetic power to the generators, taking into account the manufacturability of their implementation; the features of the change in the tooth zone of high-power machines are shown, due to the low rotation speed of the generators in gearless installations and justified for this reason, the possibility of using the "meander" winding.
In such type of winding each phase is made in the form of a single continuous conductor, which eliminates the connection of sections in phase, which takes place in traditional windings, and reduces the resistance of the winding due to the absence of one frontal part in comparison with the coil section. When solving the manufacturing technology of such windings in the form of a copper bus, it is possible to increase the fill factor of the slots and the power of the generator in certain dimensions. It is possible to manufacture such a winding of cables, in this case the three-phase winding will represent three cables, which will simplify its manufacture, but the fill factor of the slots will be less.
In the paper different options of meander windings are compared in order to simplify their manufacture and traditional loose windings with a different number of slots per pole and phase in order to increase the tooth pitch and simplify the manufacture of the stator core and winding.

Ref. 9, tabl. 1, fig. 5. В основу работы положены результаты расчетов ряда синхронных безредукторных ветрогенераторов модульных конструкций [1] с возбуждением от постоянных магнитов NdFeB мощностью (600÷3600) кВт при принятой за рубежом расчетной скорости ветра – 12,5 м/с. Такой подход исследования машин позволяет оценить сложную взаимосвязь их параметров при минимуме допущений, в частности, учесть насыщение наиболее нагруженных участков магнитной цепи и определить целесообразность применения некоторых возможных вариантов обмоток, которые обеспечивают наибольшую электромагнитную мощность генераторов с учетом технологичности их выполнения; показаны особенности изменения зубцовой зоны машин повышенной мощности, обусловленные низкой скоростью вращения генераторов в безредукторных установках и обоснована по этой причине возможность применения "меандровой" обмотки. В такой обмотке каждая фаза выполняется в виде одного непрерывного проводника, что позволяет исключить соединение секций в фазе, имеющее место в традиционных обмотках, уменьшить сопротивление обмотки благодаря отсутствию одной лобовой части в сравнении с витком секции. При решении технологии изготовления таких обмоток в виде шины возможно повышение коэффициента заполнения пазов и мощности генератора в определенных габаритах. Возможно изготовление такой обмотки кабелями, в этом случае трехфазная обмотка будет представлять три кабеля, что позволит упростить её изготовление, но коэффициент заполнения пазов будет меньше. В работе проведено сравнение различных вариантов меандровых обмоток с целью упрощения их изготовления и традиционных всыпных обмоток с различным количеством пазов на полюс и фазу с целью увеличения зубцового шага и упрощения изготовления пакета статора и обмотки.
