Configure Summations

This section describes how to configure calculation of Summations data based on the controller's online data. For more detail information, refer to Summations Log.

To accomplish the task described above, we have to take some basic steps, including

create a data set;
assign this data set to a controller;
configure data items for which we want to calculate summations.

First of all, you will require the Data Set Manager plug-in in MiScout Desk to enable collecting Summations from the controller. For more detail information, refer to Configuring Plug-ins.

Follow the steps below to create a data set:

in the Show section of the Data Set Manager toolbar click ;
in the New section of the Data Set Manager toolbar click ;
type Summations in the Data Set Setup window in the Name field;
click OK to proceed.

Now we need to assign a created Summations data set to the controller named Unit 01. To do this, follow the steps below:

select the Controller Configuration window in the main presentation area and select Unit 01 in the Controller View window;
expand the node SCADA log in the Property window;
select the Summations log data set drop-down arrow to reach the list of data sets;
select the Summations option button and click OK;
to start automatic data gathering and calculation on the controller according to the recently created data sets and mapping, select the Auto start field and set its value to True.

After the Summations data set is created and assigned to the controller called Unit 01, the next step to take is data items configuration, for which we want to calculate summations.

Let's first configure Service summation, which is responsible for calculating counters and is assigned to the digital channels. In our case, we will configure the summation responsible for the turbine clockwise yawing. MiScout database already contains such summation named as Yaw Motor CW summation.

Therefore, for successful configuring of Yaw Motor CW summation, take the steps below:

select the Data Set Manager window and drag-and-drop the Yaw CW Auto Active item to the recently created data set Summations in the Data sets window to the right;

Note. You can use filter to simplify the way of searching the required items by simply typing the required word in the appropriate field.

right click Yaw CW Auto Active in the Data sets window and select Edit Data Item;
in the Edit data item window we need to specify the output data class for this summation (i.e. the way it will be presented in the system). Click the Output Data class drop-down arrow to reach the list of data classes available in the database;
in the Output Data class drop-down arrow expand the node Parent: WYAW.MotCw.stCt and double-click WYAW.MotCw.stCt.ctTot;

click OK to proceed.

In the situation, when a specific item required for summation is not available in the database, it can be created by a user. To do this, we need to create Parent (the required item) which will contain fields within responsible for the count, active time and reset time. Let's create the Nacelle Fan item as well as the corresponding data classes for this item in the following way:

in the Show section of the Data Class Editor toolbar click to see all available data classes;
drag-and-drop the Parent column header next to the Group button. This will provide you with a more comfortable view for performing the following configuration;

right click Group: WNAC in the Data classes area and select Data Class;
type WNAC.Fan.stct in the Name field in the Edit data class window;
type nacelle fan in the Description field;
select Summation in the Data type drop-down list;
select Total in the Item type drop-down list;
click OK to proceed.

Once the Parent is created, we can proceed with creating fields responsible for the count, active time and reset time in the following way:

right click Parent: WNAC.Fan.stct and select Data Class;
type WNAC.Fan.stCt.ctTot in the Name field;
in the Parent drop-down list select WNAC.Fan.stct, we have previously created;
select Activation counts in the Data type drop-down list;
select Total in the Item type drop-down list;
click OK to proceed.

Do the same for the total active time and reset time. Having finished the configuration and applied all changes, data classes should appear in the Data classes panel as on the picture below.

To be able to add a recently created data class to Summations data set, we need to create a mapping. For more detail instructions, refer to Create Data Mapping .

Now you can add the Nacelle Fan item to Summations data set and specify the created data class WNAC.Fan.stct as was already done with Yaw CW Auto Active.

Now let's create Energy summation by following the steps below:

select the Data Set Manager window and drag-and-drop Grid Power and Grid Reactive Power items to the Data Set window to the created data set named Summations;
right click Grid Power in the Data sets window and select Edit data item;
in Edit data item click the Output Data class drop-down arrow to reach the list of data classes existing in the database;
expand the node Parent: WTUR.TotEgy and double click total produced active power WTUR.TotEgyAt.mag.f;
click OK to proceed.

Do the same for Grid Reactive Power by selecting total produced reactive power WTUR.TotEgyReact.mag.f in the list of existing data classes.

Apply the changes by clicking in the upper left corner, so they will be saved on the server.

After configuring the items, you will be able to calculate Service and Energy summations based on the configured data received from the controller.

The next manual section Configure Status and Event Logs chapter will provide you with the instructions on how to configure calculation of Status Log and Event Log from the controller.
