В статье рассматривается опыт эксплуатации ветроэнергетического комплекса с ветроэлектрической установкой малой мощности (5 кВт), применение которого перспективно для электроснабжения удаленных объектов нефтедобычи, геологоразведочных и других видов работ по добыче полезных ископаемых. Приведена структура исследуемого комплекса и его характеристики, технические проблемы, возникшие при эксплуатации в течение 6 лет. Рассмотрены элементы ветроэнергетического комплекса – регулятор заряда аккумуляторных батарей и инвертор-преобразователь. Рассмотрены последствия выхода из строя механического регулятора заряда аккумуляторных батарей и представлены рекомендации по его замене. Подробно освещены вопросы диагностики и ремонта одного из основных элементов комплекса – инвертора- преобразователя, его составной части – звена постоянного тока. Представлены осциллограммы выходного напряжения инвертора-преобразователя при различной емкости звена постоянного тока и приведены изображения отремонтированного инвертора-преобразователя. Даны рекомендации по выбору инвертора- преобразователя и настройке режимов работы ветроэнергетического комплекса.

The article discusses the experience of operating a wind power complex with a low-power wind power installa- tion (5 kW), the use of which is promising for powering remote oil production facilities, exploration and other types of mining operations. The structure of the studied complex and its characteristics, technical problems that have arisen during operation for 6 years are given. The elements of the wind energy complex – the battery charge regulator and the inverter-converter are considered. The consequences of the mechanical regulator failure of battery charge are con- sidered and recommendations for its replacement are presented. The issues of diagnostics and repair of one of the main elements of the complex – the inverter-converter, its component – DC link are highlighted in detail. Oscil- lograms of the output voltage of the inverter-converter are presented for different capacities of the DC link and the images of the repaired inverter-converter are given. Recommendations are given on choosing an inverter-converter and setting up the operating modes of the wind energycomplex.
