2 присоединение (в электроэнергетике)
присоединение (в электроэнергетике)
Совокупность коммутационных аппаратов, обеспечивающих соединение линии электропередачи, трансформатора или другого оборудования со сборными шинами.
Примечание. Коммутационные аппараты, принадлежащие одному присоединению, характеризуются общностью управления в нормальных, аварийных и ремонтных режимах, включая управление, защиту и оперативные блокировки. Уровень присоединения в системе автоматизации подстанции представляет собой уровень управления, находящийся ниже общего станционного уровня.
[ ГОСТ Р 54325-2011 (IEC/TS 61850-2:2003)]
присоединение
Электрическая цепь (оборудование и шины) одного назначения, наименования и напряжения, присоединенная к шинам РУ, генератора, щита, сборки и находящаяся в пределах электростанции, подстанции и т.п. Электрические цепи разного напряжения одного силового трансформатора (независимо от числа обмоток), одного двухскоростного электродвигателя считаются одним присоединением. В схемах многоугольников, полуторных и т.п. схемах к присоединению линии, трансформатора относятся все коммутационные аппараты и шины, посредством которых эта линия или трансформатор присоединены к РУ

bay
a substation consists of closely connected sub parts with some common functionality. Examples are the switchgear between an incoming or outgoing line, and the busbar, the bus coupler with its circuit breaker and related isolators and earthing switches, the transformer with its related switchgear between the two busbars representing the two voltage levels. The bay concept may be applied to 1½ breaker and ring bus substation arrangements by grouping the primary circuit breakers and associated equipment into a virtual bay. These bays comprise a power system subset to be protected, for example a transformer or a line end, and the control of its switchgear that has some common restrictions such as mutual interlocking or well-defined operation sequences. The identification of such subparts is important for maintenance purposes (what parts may be switched off at the same time with minimum impact on the rest of the substation) or for extension plans (what has to be added if a new line is to be linked in). These subparts are called ‘bays’ and may be managed by devices with the generic name ’bay controller’ and have protection systems called ‘bay protection’.
The concept of a bay is not commonly used in North America. The bay level represents an additional control level below the overall station level
