干擾記錄器DRPRDRE
擾動記錄儀功能提供有關電力系統(tǒng)擾動的快速、完整和可靠信息。它有助于理解擾動期間和之后的系統(tǒng)行為以及相關的一次和二次設備。記錄的信息用于短期（例如糾正措施）和長期（例如功能分析）的不同目的。干擾記錄器從連接到干擾報告功能的選定模擬和二進制信號（最多40個模擬和96個二進制信號）中獲取采樣數據。可用的二進制信號與事件記錄器功能相同。該功能具有很大的靈活性，不依賴于保護功能的操作。它可以記錄保護功能未檢測到的干擾。觸發(fā)瞬間前最多十秒鐘的數據可保存在干擾文件中。最多100個干擾的干擾記錄器信息保存在IED中，本地HMI用于查看記錄列表。事件功能當使用帶有LON或SPA通信的變電站自動化系統(tǒng)時，時間標記事件可以在變化時發(fā)送，也可以從IED循環(huán)發(fā)送到站點級別。這些事件是根據IED中連接到事件功能（Event）的任何可用信號創(chuàng)建的。事件功能塊用于LON和SPA通信。模擬和雙指示值也通過EVENT功能傳輸。IEC61850通用通信I/O功能SPGGIO IEC61850General communication I/O功能（SPGGIO）用于向變電站中的其他系統(tǒng)或設備發(fā)送單個邏輯信號。IEC61850通用通信I/O功能MVGGIO IEC61850General communication I/O functions（MVGGIO）功能用于將模擬信號的瞬時值發(fā)送到變電站的其他系統(tǒng)或設備。它也可以在同一IED內使用，將RANGE（量程）方面附加到模擬值，并允許對該值進行測量監(jiān)督。測量值擴展器塊RANGE_XP電流和電壓測量功能（CVMMXN、CMMXU、VMMXU和VNMMXU）、電流和電壓順序測量功能（CMSQI和VMSQI）以及IEC 61850通用通信I/O功能（MVGGIO）均具有測量監(jiān)督功能。所有測量值都可以通過四個可設置的限值進行監(jiān)控：下限、下限、上限和上限。引入測量值擴展器塊（RANGE_XP），將測量函數的整數輸出信號轉換為5個二進制信號：低于下限、低于下限、正常、高于上限或高于上限。輸出信號可用作可配置邏輯中的條件或用于報警目的。
脈沖計數器邏輯PCGGIO
脈沖計數器（PCGGIO）功能統(tǒng)計外部生成的二進制脈沖，例如來自外部電能表的脈沖，以計算能耗值。脈沖由二進制輸入模塊捕獲，然后由功能讀取?？赏ㄟ^站點總線獲得縮放服務值。必須訂購具有增強脈沖計數功能的特殊二進制輸入模塊才能實現此功能。能量計算和需求處理功能ETPMMTR測量輸出（CVMMXN）功能可用于計算能耗。有功值和無功值按輸入和輸出方向計算。值可以作為脈沖讀取或生成。最大需求功率值也由函數計算。14.基本IED功能時間同步時間同步源選擇器用于選擇IED作為保護系統(tǒng)一部分時的通用絕對時間源。這使得可以比較電站自動化系統(tǒng)中所有IED之間的事件和干擾數據。15.人機界面人機界面本地人機界面有小型和中型兩種型號。這兩種型號的區(qū)別在于LCD的尺寸。小尺寸LCD可以顯示七行文本，中等尺寸LCD可以在每頁上顯示最多15個對象的單線圖。根據產品功能，最多可以定義12個單線圖頁面。本地HMI分為具有不同功能的區(qū)域。?狀態(tài)指示LED。?報警指示LED，由15個LED（6個紅色和9個黃色）組成，帶有用戶可打印標簽。所有LED均可從PCM600配置。?液晶顯示器（LCD）。?帶有用于控制和導航的按鈕的小鍵盤，用于在本地和遠程控制之間進行選擇和重置。?隔離的RJ45通信端口。
Disturbance recorder DRPRDRE
The Disturbance recorder function supplies fast, complete and reliable information about disturbances in the power system. It facilitates understanding system behavior and related primary and secondary equipment during and after a disturbance. Recorded information is used for different purposes in the short perspective (for example corrective actions) and long perspective (for example functional analysis). The Disturbance recorder acquires sampled data from selected analog- and binary signals connected to the Disturbance report function (maximum 40 analog and 96 binary signals). The binary signals available are the same as for the event recorder function. The function is characterized by great flexibility and is not dependent on the operation of protection functions. It can record disturbances not detected by protection functions. Up to ten seconds of data before the trigger instant can be saved in the disturbance file. The disturbance recorder information for up to 100 disturbances are saved in the IED and the local HMI is used to view the list of recordings. Event function When using a Substation Automation system with LON or SPA communication, time-tagged events can be sent at change or cyclically from the IED to the station level. These events are created from any available signal in the IED that is connected to the Event function (EVENT). The event function block is used for LON and SPA communication. Analog and double indication values are also transferred through EVENT function.IEC61850 generic communication I/O function SPGGIO IEC61850 generic communication I/O functions (SPGGIO) is used to send one single logical signal to other systems or equipment in the substation. IEC61850 generic communication I/O functions MVGGIO IEC61850 generic communication I/O functions (MVGGIO) function is used to send the instantaneous value of an analog signal to other systems or equipment in the substation. It can also be used inside the same IED, to attach a RANGE aspect to an analog value and to permit measurement supervision on that value. Measured value expander block RANGE_XP The current and voltage measurements functions (CVMMXN, CMMXU, VMMXU and VNMMXU), current and voltage sequence measurement functions (CMSQI and VMSQI) and IEC 61850 generic communication I/O functions (MVGGIO) are provided with measurement supervision functionality. All measured values can be supervised with four settable limits: low-low limit, low limit, high limit and high-high limit. The measure value expander block (RANGE_XP) has been introduced to enable translating the integer output signal from the measuring functions to 5 binary signals: below low-low limit, below low limit, normal, above high-high limit or above high limit. The output signals can be used as conditions in the configurable logic or for alarming purpose.
Pulse counter logic PCGGIO
Pulse counter (PCGGIO) function counts externally generated binary pulses, for instance pulses coming from an external energy meter, for calculation of energy consumption values. The pulses are captured by the binary input module and then read by the function. A scaled service value is available over the station bus. The special Binary input module with enhanced pulse counting capabilities must be ordered to achieve this functionality. Function for energy calculation and demand handling ETPMMTR Outputs from the Measurements (CVMMXN) function can be used to calculate energy consumption. Active as well as reactive values are calculated in import and export direction. Values can be read or generated as pulses. Maximum demand power values are also calculated by the function. 14. Basic IED functions Time synchronization The time synchronization source selector is used to select a common source of absolute time for the IED when it is a part of a protection system. This makes it possible to compare event and disturbance data between all IEDs in a station automation system. 15. Human machine interface Human machine interface The local human machine interface is available in a small and a medium sized model. The difference between the two models is the size of the LCD. The small size LCD can display seven lines of text and the medium size LCD can display the single line diagram with up to 15 objects on each page. Up to 12 single line diagram pages can be defined, depending on the product capability. The local HMI is divided into zones with different functionality. ? Status indication LEDs. ? Alarm indication LEDs, which consist of 15 LEDs (6 red and 9 yellow) with user printable label. All LEDs are configurable from PCM600. ? Liquid crystal display (LCD). ?
