ICS TRIPLEX T8800控制模塊
同步時鐘2來自同步檢查功能的信號的I/P,屬于CB2。
設置為“開”(“T”或“真”),如果不需要,則不安裝和“死”未使用第2行或“ExtSCBypas”。
用于啟用關閉命令的I/P邏輯:[('synchrocheck2'和“CO就緒2”)或“死線2”或“ExtSCBypas”]。
死線2 I/P指示2號線斷電(CB2開路和v.t2在母線側)。
如果不需要,則設置為“off”(“F”或“False”)。
活動I/P覆蓋以下邏輯關系:I/P:“同步檢查2”和“CO就緒2”。如果兩個斷路器在故障之前閉合,則只有首選斷路器執行整個自動重合閘循環。另一個斷路器在成功后閉合自動重合閘或當關閉命令為首選時
斷路器未啟用(缺少“CO就緒”或“同步檢查”)。
(附加邏輯)只有安裝了特殊自動重合閘邏輯時,以下設置才具有重要意義。
在這種情況下,請咨詢各種設置的重要性說明。
BOOL_IN1,BOOL_ IN2…BOOL單元IN16特殊自動重合閘邏輯的額外二進制輸入。
定時器1、定時器2…定時器8特殊自動重合閘邏輯的附加定時器設置。
BOOL_OUT1,BOOL_ OUT2…BOOLUOUT8
特殊自動重合閘邏輯的附加信號。
項目目錄
用戶可以選擇存儲自動重合閘邏輯的子目錄。當使用MMI目錄中的標準邏輯時,默認名稱“AURESTD”適用。使用特殊邏輯時,需要更改名稱和路徑。在這種情況下,請參閱相關的說明程序.一般
自動重合閘功能可執行1至4次自動重合閘嘗試。第一次嘗試可以是單次嘗試,也可以是而隨后的嘗試總是三相的。類型和數量由參數決定“1.AR模式”(第一次重合閘循環的4種不同模式)和“2..4 AR模式”。
該功能可與外部距離保護繼電器或其他內部保護功能。
它也可以在包含兩個或更多保護功能的方案中運行(見第3.5.32.2節至第3.3.32.5節)。
SynchroChck2
I/P for a signal from a synchrocheck function belonging to
CB2.
Set to ‘on’ (‘T’ or ‘True’), if not needed, not fitted and ‘Dead
line 2’ or ‘ExtSCBypas’ not used.
I/P logic for enabling the close command: [(‘synchrocheck2’
AND ‘CO Ready 2’) OR ‘Dead line 2’ OR ‘ExtSCBypas’].
Dead line 2
I/P indicating that line 2 is de-energised (CB2 open and v.t’s
2 on the busbar side).
Set to ‘off’ (‘F’ or ‘False’), if not needed.
An active I/P overrides the following logical relationship of the
I/P’s: ‘synchrocheck 2’ AND ‘CO Ready 2’.If both circuit-breakers are closed before a fault, only the preferred circuit-breaker performs the entire auto-reclosure cycle. The other circuit-breaker closes either after successful
auto-reclosure or when the close command to the preferred
circuit-breaker is not enabled (missing ‘CO Ready’ or ‘Synchrocheck’).
(ADDITIONAL LOGIC)
The following settings are only of consequence if a special autoreclosure logic is installed. In this case, consult the associated
description for the significance of the various settings.
BOOL_IN1, BOOL_IN2…BOOL_IN16
Additional binary input for a special auto-reclosure logic.
TIMER_1, TIMER_2…TIMER_8
Additional timer settings for a special auto-reclosure logic.
BOOL_OUT1, BOOL_OUT2…BOOL_OUT8
Additional signals for a special auto-reclosure logic.PROJECT DIRECTORY
The user can choose the subdirectory in which to store the autoreclosure logic. The default name “AURESTD” applies when using the standard logic in the MMI directory.
It is necessary to change the name and path when using a special logic. In this case, consult the associated description for the
procedure.General
The auto-reclosure function can perform from 1 to 4 autoreclosure attempts. The first attempt can be either single or
three-phase while the subsequent attempts are always threephase. The type and number are determined by the parameters
‘1. AR Mode’ (4 different modes for the 1st. reclosure cycle) and
‘2..4 AR Mode’.
The function can operate in conjunction with either an external
distance protection relay or other internal protection functions.
It can also operate in a scheme comprising two or more protection functions (see Sections 3.5.32.2. to 3.5.32.5.).
