Снижение эксплуатационных затрат в системах охлаждения автотрансформаторов для повышения их энергоэффективности
The issues of implementing effective measures to reduce losses during the operation of power electrical equipment are of particular practical interest for electric grid and industrial enterprises. In nominal and close to them modes, power transformers have a fairly high coefficient of performance (COP). However, the efficiency of autotransformers depends on many factors due to their design features. In this study, the authors propose a method for improving the energy efficiency of autotransformers while optimizing the functioning of their cooling system in order to reduce operating losses for electric drives of pumps and fans of forced cooling systems using an autotransformer with a rated power of 125 MVA as an example.
Вопросы внедрения эффективных мероприятий по снижению потерь при эксплуатации силового электрооборудования представляют практический интерес для электросетевых и промышленных предприятий. В номинальных и близких к ним режимах силовые трансформаторы обладают высоким коэффициентом полезного действия (КПД). Однако из-за конструктивных особенностей автотрансформаторов их КПД зависит от многих факторов. На примере автотрансформатора АТДЦТН-125000/220/110-У1 номинальной мощностью 125 МВ·А предложен способ повышения энергоэффективности при оптимизации функционирования их системы охлаждения с целью снижения эксплуатационных потерь на электроприводы насосов и вентиляторов систем принудительного охлаждения.
