  • Annunciation Checker1 Annunciation CheckerToday's protection relays are able to emit hundreds of different signals and measured values. Especially during station commissioning it is necessary to check the correct assignment of signals and measured values to the different locations. Annunciation Checker enables the user to generate the signals and to check their correct appearance at the respective locations. It is possible to prepare the signals in a test document and to adapt them to the actual substation equipment even during testing.

    Annunciation Checker provides 5 different views:

  • Annunciation CheckerDetail ViewThis view is used for the following:

    To predetermine the type of signal to be output at the analog outputs of the CMC.

    The following three selections are available:

    Shot Signal output is limited by time or stopped by trigger condition. Duration and prefault current are adjustable.

    Steady state Continuous signal output.no output No signal output. It is only possible to define

    instructions and pop-up messages.

    To set the magnitude, phase angle and frequency of the analog CMC outputs required to generate the message.

    For this purpose, 9 different set modes are available for selection:

    1. Direct (Line-Neutral)Input of line-neutral voltages, currents and frequencies.

    2. Line-LineInput of line-line voltages, currents and frequencies.

    3. Symmetrical ComponentsInput of positive, negative and zero sequence voltages and currents.

    1.1.1 Test TaskIn substation Center, operated by Energy Supply XX Inc., the SIEMENS distance protection relay 7SA631 is used as main protection for the cable connected to feeder =E01. As part of commissioning all signals and measured values are to be checked at the different annunciation locations. The test set CMC 156 is available as test instrument.

    The following explanation describes the commissioning test for feeder =E01 of a multifunctional relay using the Annunciation Checker test module with a test document created in the OMICRON Control Center. Although your specific application will require some modification, the general procedure still stays the same.

    Commissioning testing of a protection relay requires the following:

    - All messages and measured values transmitted from the protection device to the various annunciation locations.

    - All locations where the messages and measured values are displayed.

    - The test settings required to generate the corresponding messages and measured values.

    1.1.2 Preparing the TestBelow, the creation of a complete test document in the OMICRON Control Center is described. The functionality of both the used Annunciation Checker test module and the entire system is explained. For specific information please refer to the online help.

    Prior to the actual test, the following main steps have to be performed:

    1. Setting the document layout (outside), refer to chapter "OMICRON Control Center" in the software manual "The Concept".

    2. Entering the relay and test object parameters, refer to chapter 1.1.3.

    3. Configuring the test set hardware, refer to chapter 1.1.4.

    4. Configuring the test module, refer to chapter 1.1.5.

    1.1.3 Defining the Test ObjectDefinition of the relay under test is performed using the Test Object software function. Open Test Object by selecting the menu item P A R A M E T E R S | T E S T

    O B J E C T or by clicking with the left mouse button on the Test Object item in the toolbar. In Test Object the test object parameters can be accessed and edited.

  • 1OMICRON Test UniverseA detailed description of Test Object and the closely related subject "XRIO" can be found in section 3 Setting Up the Test Object of the "Concept" manual, or in the online help under the --- Test Object --- entry of the table of contents.

    There are two general methods to make the relay parameters available for the test system:

    1. Defining the test object data in the test document (global declaration).

    2. Defining the test object data in each single test module using P A R A M E T E R S | T E S T O B J E C T.

    The first method should be used if several tests are performed for one test object using different test modules. The test object is then automatically available for all subsequent test modules.

    Insert a test object and specify the distance protection parameters. Nominal values of the relay: In= 1A, Vn = 100V.

    - Position the cursor to the beginning of the test document.

    - Select the menu item I N S E R T | T E S T O B J E C T.

    Step 1: Definition of general data1. In the tree structure of the Test Object dialog, select the branch R I O |

    D E V I C E .

    2. Click the E D I T button to enter the general data of the protection relay.

    3. In the subsequently opened Device Settings dialog enter the general data as shown in figure 1-7.0

    The assessment buttons are activated after the test step is finished.

  • 2OMICRON Test Universe4. Assess the test step with Passed or Failed.If the test step is assessed with Passed, the expected (nominal) value is automatically entered into the "Measured" field. If wanted, you can now modify this value manually. This suggests itself especially in case of measured voltages and currents to enter the actual measured value.

    If the test step is assessed with Failed, the expected (nominal) value is not entered into the "Measured" field. In this case the message is assessed as failed in the input table.

    5. Use the navigation arrow buttons to select the next message to be tested.

    Testing can be stopped at any time using the "Stop test" button and re-started again using the start icon in the toolbar.
