About this chapter
This chapter describes how a project is defined, created and managed by CCT.
1 Managing projects in CCT
The CCT manages a project in its own data base per project. CCT uses the MicroSoft Access Data Base. The CCT projects can be stored and managed at a place which is selected by the user.
It is possible
• to open projects
• to create new projects
• to save the actual project
• to close projects
A CCT project is identified by its suffix "project.mdb".
Figure 47: CCT: Handling Projects Open Project
• select File > Open Project to open an existing project. This is only possible when no project is active at this time. When you want to run another project you have to close the running one first.
• a MicroSoft standard window to select a file pops up. Rout to your directory where the project you want to open is stored.
• select the project and open it
CCT will read the data base and opens the project. This will take some time and is partly shown in a progress bar at the bottom of the CCT window.
When the project is loaded you may check that it is the one you are looking for. A typical sta-tion.scd project may look like the figure below shows in the four SCL sections. The right screen-shot shows the structure with available DataSets and report control blocks below a LLN0.

Figure 48: CCT: Section view in the Project Navigator Create new Project
• select Create new Project
• a Create new Project window pops up
• type a name for the new project
• browse to the location where you want to store the CCT project (Project Path)
• press OK, which is enabled when a project path is defined

Figure 49: CCT: Create new Project
CCT prepares the basics in the data base and generates the internal structure of an IEC 61850 SCL file. When it has finalized its preparation task the Project Navigator shows a basic structure with a placeholder in the substation section for a first Voltage Level and under the Data Type Templates section the list of IEC 61850 defined Base types of type Enum. The IED and Com-munication sections are empty.
Save
• this action is always possible
CCT stores all values in the data base, so all additions and modifications are taken to the data base.
Close Project
• this action is always possible
CCT asks to save the changes made, when it shall close the project and changes are pending.
CCT will close the project which will take some time when it has to save the project before.

2 Import/export station.SCD files
CCT as a tool for IEC 61850 signal engineering can do this tasks for a single IED or for a com-plete station with all IEDs linked to communication and defined in the substation section of the SCL file.
This section describes the import and export of a station.SCD file.
2.1 Import station.SCD file
• select Tools > SCL Import/Export > Import SCL File
• a window pops up to prepare the file which should be imported
• select Browse and rout to the final directory where the station.SCD file you want to import is located
• select the SCD file. You may have to change the file-type to *.SCD to get the available files visible.
• CCT checks the file to be a SCL file. If the check is successful the Import button will be highlighted
• select/ check Delete superfluous Data not represented in SCL file to be selected
• press Import
Figure 50: CCT: Import / export station.SCD file
CCT starts to read the station.SCD file and prepares the internals to operate the project with the file. This will take some time and is partly shown in a progress bar at the bottom of the CCT window.
en06000118.vsd
When the file is established you may check that it is the one you was looking for. A typical sta-tion.scd project may look like shown in figure 48
2.2 Export station.SCD file
• save your project before
• select Tools > SCL Import/Export > Export SCL File
• an export window will pop up which shows a default place where CCT will store the station.SCD file. This is done in the directory “SCL” below the directory where the project is stored. This directory will be created by CCT if it does not exist.
• browse and select another place and/or name for the file when necessary
• press Export
The CCT will generate a station.SCD file by keeping those parts which are not touched by the CCT which is the Substation and Data Type Templates section. The communication and IED section may have been modified and extended by CCT.
In addition CCT creates a set of ied.ccf files per IED in the project. These files include the SCL part which is of interest for the named IED only. They may be used to re-import the IED part to the IED configurator tool directly. These files are located at the same place as the station-SCD file.
3 Import/export ied.ICD files
CCT as a tool for IEC 61850 signal engineering can do this tasks for a single IED or for a com-plete station with all IEDs linked to communication and defined in the substation section of the SCL file.
This section describes the import and export of an ied.ICD file.
CCT can be used to configure DataSets and report control blocks (BRCBs) for a single IED be-fore it is integrated in a station project. This makes sense when the IED is used more then once in the project. Import of the ied.ICD file to CCT, do DataSet and BRCB engineering and export it back allows to use the extended IED as a template for similar or same control or protection IEDs.
In the actual version of PCM 600 it is only possible to include client IEDs in a station project via CCT.
3.1 Import ied.ICD file
• select Tools > SCL Import/Export > Import ICD File
• a window pops up to prepare the file which should be imported
• select Browse and rout to the final directory where the ied.ICD file you want to import is located
• select the ICD file
• CCT checks the file to be a SCL file. If the check is successful the Import button will be highlighted
• you can select more then one ied.ICD file to be imported at the same time. Repeat
“Browse” until all files you may import are selected.
• check that the files you want to import are selected. The function “Generate de-faults for MicroSCADA” is not supported in this CCT version.
• press Import
Figure 51: CCT: Import / export ied.ICD file
CCT starts to read the ied.ICD file and prepares the internals to operate the project with the file(s). This will take some time and is partly shown in a progress bar at the bottom of the CCT window.
When the file(s) is/are established you may check that they are the ones you was looking for.
3.2 Import of a client IED via CCT into a station project
A client IED will be imported in the same way as described above. To integrate it in a station project you have to load the station project first and then import the client IEDs in addition.
• load the station project to which the client IEDs belong
• import the client IEDs as described
• check the client IEDs in the IED section. They must be presented in the tree struc-ture as given in chapter 6, section 1, fiure 48. A client IED contains a logical de-vice and at least three Logical nodes, the two standards plus a client specific LN of group “I” (ITCI or IHSI).
• select the access point of the IED in the Project Navigator and configure the network name out of the drop list in the Propertiespane. It must be the same sub-network then the other IEDs are connected to.
• define the Access Point Name according to the rules of the project
• repeat the steps for all imported client IEDs
• save the project, close the project and open the project again
• the client IEDs are now completely included in the SCL structure of the IED sec-tion and in the communicasec-tion secsec-tion
en06000117.vsd
• they are not included in the substation section. In this case it is a formal informa-tion which has no influence on the normal signal engineering for reports or for GOOSE messages
3.3 Export ied.ICD file
• save your project before
• the export of an ied.ICD file is only possible when the specific IED is selected.
Select the IED in the Project Navigator and press the right mouse button. Select Export ICD
• an export window will pop up which shows a default place where CCT will store the station.SCD file. This is done in the directory “SCL” below the directory where the project is stored. This directory will be created by CCT if it does not exist.
• browse and select another place and/or name for the file when necessary
• press Export
Figure 52: CCT: Export ied.ICD file
The CCT will generate an ied.ICD file for the selected IED. The file may be re-imported to the IED configurator tool for further use.
