Aleksandr V. Prokudin, Leading engineer, Senior lecturer of the Department “Power Stations, Networks and Power Supply Systems”, South Ural State University, Chelyabinsk, Russia; prokudinav@susu.ru. Anton V. Korzhov, Dr. Sci. (Eng.), Ass.

Рассмотрена работа известного тиристорного устройства гашения магнитного поля синхронного генератора. Показано, что для улучшения характеристик устройства и расширения его функциональных возможностей при известном алгоритме управления требуется увеличение числа гасящих цепей. Предложен алгоритм управления гасящими цепями, основанный на принципе двоичного кодирования десятичного значения требуемого эквивалентного сопротивления устройства. Для двух вариантов схем тиристорных устройств гашения поля получены вольтамперные характеристики устройства. Отмечены увеличение среднего значения напряжения на выводах обмотки возбуждения и повышение качества синтезирования требуемой вольтамперной характеристики. Выявлены достоинства и недостатки предложенных алгоритмов и схем. Доказано, что переход на новый алгоритм управления гасящими цепями улучшает характеристики тиристорного устройства гашения магнитного поля синхронного генератора без необходимости изменений в силовой части, однако требует принятия мер по повышению надежности системы управления. The article considers the operation of a commonly known thyristor device for dampening a synchronous generator magnetic field. Improvement in the characteristics of the device and expansion of its functionality with a known control algorithm requires an increase in the number of quenching circuits. The article proposes an algorithm for controlling damping circuits based on the principle of binary coding of the decimal value of the required equivalent resistance of the device. The current-voltage characteristics of the device have been determined for two variants of circuits of thyristor field damping devices. An increase in the average value of the voltage at the terminals of the excitation winding and an increase in the quality of synthesizing the required current-voltage characteristic were noted. The article further describes the advantages and disadvantages of the described algorithms and schemes. It has been proven that the transition to a new control algorithm for damping circuits improves the characteristics of the thyristor device for dampening the synchronous generator magnetic field without the need for changes in the power section. However, this requires measures to be taken, in order to improve the reliability of the control system.
