Последнее техническое решение принято в качестве прототипа.  The last technical decision was made as a prototype.

В последние годы с целью упрощения проводного монтажа, повышения надежности, обеспечения интероперабельности (способности к взаимодействию по открытому интерфейсу) и взаимозаменяемости аппаратуры управления от разных производителей осуществляется переход к цифровым подстанциям, т. е к полностью цифровому способу обмена информацией в пределах электрической подстанции и далее - с удаленными центрами управления. Принципы организации такого обмена оговорены набором международных стандартов МЭК 61 850 «Системы и сети связи на подстанциях». Эти стандарты регламентируют две шины сетевого обмена по протоколу передачи данных Ethernet.  In recent years, in order to simplify wiring, increase reliability, ensure interoperability (interoperability via an open interface) and interchangeability of control equipment from different manufacturers, a transition to digital substations, i.e., to a fully digital way of exchanging information within an electrical substation, and more - with remote control centers. The principles for organizing such an exchange are stipulated by the set of international standards IEC 61 850 “Communication systems and networks at substations”. These standards govern two network bus over Ethernet protocol.
Одна шина, называемая шиной процесса, обеспечивает быстрый обмен сигналами, требующими высокопроизводительной обработки, стандартизирована протоколом МЭК 61850-9-2 и используется для передачи цифровых значений токов и напряжений, передачи GOOSE-сообщений релейной защиты. Другая шина, называемая станционной шиной, обеспечивает более медленный обмен информацией, не требующей высокопроизводительной обработки, стандартизирована протоколом МЭК 61 850-8-1 и используется для обмена данными и командами между комплексом релейной защиты и автоматики (РЗА), комплексом автоматизированной системы управления технологическим процессом (АСУТП) верхнего уровня подстанции и различными интеллектуальными электронными устройствами, подключенными к шине процесса. One bus, called the process bus, provides a fast exchange of signals requiring high-performance processing, standardized by the IEC 61850-9-2 protocol and is used to transmit digital values of currents and voltages, transmit GOOSE relay protection messages. Another bus, called a station bus, provides a slower exchange of information that does not require high-performance processing, is standardized by the IEC 61 850-8-1 protocol and is used to exchange data and commands between the relay protection and automation complex, a complex of an automated process control system (APCS) of the upper level of the substation and various intelligent electronic devices connected to the process bus.
Недостаток прототипа - его неспособность обеспечить управление и мониторинг ячейки КРУ при ее использовании в качестве одного из интеллектуальных электронных устройств цифровой подстанции в соответствии с международным стандартом МЭК 61850.  The disadvantage of the prototype is its inability to provide control and monitoring of the switchgear cell when it is used as one of the intelligent electronic devices of the digital substation in accordance with the international standard IEC 61850.

Информацию о состоянии коммутационных аппаратов контроллер 3 получает непосредственно из ячейки 6 КРУ по своим дискретным входам 9 и от контроллера 1 по внутренней локальной сети 12. Команды оперативного управления от комплекса АСУТП подстанции, команды взаимных блокировок с другими ячейками, принимаемые контроллером 2 по шине 15 подстанции в соответствии со стандартом МЭК 61850-8- 1 , также передаются в контроллер 3 по внутренней сети 12.  The controller 3 directly controls the switching devices of the switchgear cell through the shaper 1 1 relay signals. The information necessary for the execution of control algorithms on the currents and voltages of the main circuits of the switchgear from digital current and voltage sensors and the emergency shutdown command from the relay protection and automation complex, controller 3 receives via process bus 16 in accordance with IEC 61850-9-2. Controller 3 receives information about the state of switching devices directly from switchgear cell 6 via its discrete inputs 9 and from controller 1 via internal local area network 12. Operational control commands from the substation control system, interlocking commands with other cells received by controller 2 via substation bus 15 in accordance with IEC 61850-8-1, they are also transferred to controller 3 via internal network 12.
Контроллер 1 собирает информацию от всех датчиков состояния ячейки КРУ (в том числе от датчиков давления в КРУЭ), реализует ее временное хранение до передачи на верхний уровень и выполняет алгоритмы диагностики состояния КРУ. Получаемую информацию и результаты диагностики контроллер 1 передает по внутренней сети 12 контроллеру 2, который транслирует ее на верхний уровень АСУТП подстанции по шине 15. Controller 1 collects information from all sensors of the state of the switchgear cell (including pressure sensors in the switchgear), implements it temporary storage until transfer to the upper level and performs algorithms for diagnosing the state of the switchgear. The controller 1 transmits the received information and diagnostic results via the internal network 12 to the controller 2, which translates it to the upper level of the substation control system via bus 15.
Локальное управление ячейкой 6 КРУ и контроль самого модуля управления и мониторинга осуществляются с сенсорного экрана 8, подключенного к порту 7 контроллера 2, с использованием внутренней сети 12 для обмена информацией с контроллерами 1 и 3.  Local control of switchgear cell 6 and control and monitoring module itself are carried out from the touch screen 8 connected to port 7 of controller 2, using the internal network 12 to exchange information with controllers 1 and 3.
Структура предлагаемого устройства обеспечивает требуемую для цифровой подстанции производительность обработки и надежность управления благодаря оптимальному распределению функций между контроллерами 1 , 2 и 3 и обмену цифровыми данными с внешними устройствами по дублированным коммуникационным шинам 15 и 16.  The structure of the proposed device provides the processing performance and control reliability required for a digital substation due to the optimal distribution of functions between controllers 1, 2 and 3 and the exchange of digital data with external devices via redundant communication buses 15 and 16.
Цифровая подстанция с ячейкой КРУ, снабженной модулем 17, работает следующим образом.  A digital substation with a switchgear cubicle equipped with a module 17 operates as follows.
Датчики 18 передают по шине 16 модулям 17 и комплексу 20 РЗА значения токов и значения напряжений главных цепей КРУ. Эти данные используются для выполнения алгоритмов управления и релейной защиты.  The sensors 18 transmit the values of currents and voltage values of the main circuits of the switchgear via bus 16 to modules 17 and relay protection complex 20. This data is used to execute control and relay protection algorithms.
Команды оперативного управления от комплекса 19 АСУТП, команды взаимных блокировок с другими ячейками от комплекса 20 РЗА принимаются модулем 17 по шине 15 подстанции. Эта же шина используется для обмена данными и командами между комплексом 20 РЗА, комплексом 19 АСУТП верхнего уровня подстанции и другими (не показанными на фиг. 2) интеллектуальными электронными устройствами, подключенными к шине 16 процесса.  The operational control commands from the control system complex 19, the interlocking commands with other cells from the relay protection complex 20, are received by the module 17 via the substation bus 15. The same bus is used for exchanging data and commands between the complex of relay protection and automation equipment, the complex 19 of the control system of the upper level of the substation and other (not shown in Fig. 2) intelligent electronic devices connected to the process bus 16.
Использование ячеек 6 КРУ, снабженных модулями 1 7, в составе цифровой подстанции повышает ее надежность управления и удобство эксплуатации.  The use of cells 6 switchgear, equipped with modules 1 7, as part of a digital substation increases its reliability and ease of operation.
