The paper presents the results of a study on hybrid filter operation and performance under hybrid power supply. In the study, a hybrid filter structure was developed and proved to perform a set of power quality improving functions. The paper demonstrates that it is necessary for the hybrid filter structure to be variable in order to adapt to changes in power supply. A case is made for using an additional passive filter at the active part output of the hybrid filter under distributed generation. The optimal structure and parameters of such an additional passive filter are identified and proved. Based on the experimental research results, the mathematical and computer simulation models of the proposed hybrid filter for hybrid power supply were developed. The modeling and simulation results showed the efficiency level to be satisfactory and power quality to improve due to applying the proposed hybrid filter. Using the modeling and simulation results, an adaptive algorithm to control the operation factors of the proposed hybrid filter under hybrid power supply was developed, tested, and evaluated. Practical recommendations for industrial application of the proposed hybrid filter are given.

Новосибирский государственный технический университет, г. Новосибирск ПриМеНеНие ПриНциПА МАКсиМУМА Для оПтиМизАции АКтиВНого фильтрА сУБгАрМоНиК тоКА В статье на основе метода оптимального управления Л. С. Понтрягина получены структура и параметры оптимального регулятора для активного фильтра субгармоник тока (АФСТ). Такой регулятор позволяет достичь полного подавления субсинхронных крутильных колебаний роторов газотурбинных установок (ГТУ) автономной электростанции на этапе возникновения и развития резонанса на одной из собственных частот крутильных колебаний ГТУ и предотвращения срабатывания виброзащиты и аварийного отключения электростанции. Подобные отключения приводят к большим экономическим и технологическим потерям. Ключевые слова: крутильные субсинхронные колебания, радиальные вибрации, активный фильтр субгармоник тока, оптимальный регулятор, математическое моделирование, автономная электроэнергетическая система с оптимальным АФСТ.

the active zone of an electromechanical transducer (ET) contains several tens of geometrical parameters, each of which has a definite influence on the technical characteristics of the generator. When building a computer model, it is impossible to reflect the influence of each single input parameter on the output. Therefore, we propose to introduce a quantitative assessment of the influence of variations in all the geometric parameters of the active zone of an electromechanical transducer on the electromagnetic parameters of technical characteristics, and then select the most significant ones.
