Главный распределительный щит с автоматическим вводом резерва на базе контроллера

Abstract

Предметом исследования является автоматический ввод резерва главного распределительного щита РУ-0,4 кВ. Основной целью магистерской диссертации является составление и исследование схемы автоматического ввода резерва на базе контроллера, определение параметров сети, таких как величина тока однофазного короткого замыкания, трехфазного короткого замыкания, токи нагрузок, токи уставок защитных аппаратов, влияющих на схему автоматического ввода резерва.Для решения поставленных задач в выпускной квалификационной работе использовался общелогический метод. Практическая значимость. Полученные результаты могут широко применяться при выполнении подобных задач, поскольку рассматриваемая сеть, для которой обеспечивается автоматический ввод резерва, не является уникальной и может неограниченно изменяться и дополняться. Выводы. В результате исследований было определено наименьшее время срабатывания блоков автоматического ввода резерва среди крупнейших производителей на российском рынке, проведен патентный обзор аналогичных решений, получены значения параметров сети, от которых зависел выбор защитной аппаратуры, составлена спецификация оборудования, представлена конструкция главного распределительного щита. Данная работа имеет практическое применение, поскольку представленная сеть снабжения является реальным объектом инфраструктуры. Дальнейшее развитие темы возможно при условии замены представленных решений на аналогичные по своим характеристикам и параметрам.

The subject of the study is the automatic input of the reserve of the main switchboard RU-0.4 kV. The main purpose of the master's thesis is to compile and study the automatic transfer circuit based on the controller, determine the network parameters, such as the magnitude of the current of a single-phase short circuit, three-phase short circuit, load currents, current settings of protective devices that affect the circuit of automatic transfer of the reserve. To solve the tasks in the final qualifying work, the general logical method was used. Practical significance. The results obtained can be widely used in performing such tasks, since the network under consideration, for which automatic reserve input is provided, is not unique and can be changed and supplemented indefinitely.Conclusions. As a result of the research, the shortest response time of automatic transfer units among the largest manufacturers in the Russian market was determined, a patent review of similar solutions was carried out, the values of network parameters were obtained, on which the choice of protective equipment depended, equipment specifications were drawn up, and the design of the main switchboard was presented. This work has practical application, since the presented supply network is a real infrastructure object. Further development of the topic is possible provided that the presented solutions are replaced with similar ones in terms of their characteristics and parameters.
