- 1. SCADA DASH BOARD Introduction According to Wikipedia, SCADA (Supervisory Control And Data Acquisition) is a system that operates with coded signals over communication channels so as to provide control of remote equipment (using typically one communication channel per remote station). Architecture SCADA dash board comprises of the Business and Operators end. Business End The business end is a web application accessible through a web browser. Each end functions independently and integrates as a whole. SCADA Setup and Usage SCADA dashboard is accessible through the URL: scada.abujaelectricity.com/SCADA- 2/XII.php NB: This will be changed subsequently to: “scada.abujaelectricity.com/SCADA/” once it has been approved to have met the end user needs. The dashboard comprises of 3 menu tabs –Power, Energy and System. It provides information as regards power, energy and disparity in time between systems respectively. To use this system, a date range needs to be provided. This is done by clicking on the input tag, which drops down a calendar menu. A date is selected and also time. NB: If no time is selected, the dashboard uses the device’s current time (Hour).
- 2. A substation is selected from the list of dynamically updated substations available on the database. A meter address is also selected in the same manner as the substation. Once all records have been provided the “Enter” button is clicked. This queries the database using the user’s input. When the server is done with the query, it returns to the user (web browser –front end) representation of records using data analytical tools such as line graphs, pie and bar charts. Below are snap shots of the Dashboard:

It was designed to work seamlessly with SATEC devices as well as many other device like raspberry pi, RTU, and PLC. The SCADA system will reads data on a continuous basis from over 2,000 meters. AEDC SCADA System Benefits Early detection of problems prevents costly damage to equipment. Power Quality Analysis enables efficientand professionalsolutions for problems throughout the grid Detect Sources of Energy inefficiency Turn customers into partners by applying a transparent policy Real-time date virtualizations. Graphical representation of real-time data. What AEDC SCADA System is for? Collects data from meters Analyzes the data Presents the information using: Tables
- 6. Line Diagrams Standard Data Displays Graphical Presentations Interactive Graphs Archiving and Display Application Highlights Navigation & Data Display through line diagram. This is a customize navigation screens, such that when operators mouse over line diagram, they get real-time data from MySQL database server.
- 7. Substation Monitoring providing one glance view of all devices on all substations.
- 8. Events and Alarms Still under development. Steps to access and use SCADA Frontend for Operators Audiences 1. Logon to your SCADA desktop system configure by IT department. 2. Open Internet Explorer or any browser of your choice. 3. On the address bar,type http://scada.abujaelectricity.com/scada3/ and press enter key on your keyboard. 4. 5. You will now be presented with a web application interface as shown below:
- 9. 6. Operators can navigate the SCADA Graphical User Interface with the left navigation panel by mouse over on AEDC SUBSTATION link. 7. AEDC SUBSTATIONpage provide a landing page to view all Injection Substations from one location. In this view, SCADA Operators are made to select substation from drop down menu as shown below: 8. Mouse over AEDC SUBSTATION link will display a submenu for injection substation areas: i. Garki Area ii. Wuse Area 9. Garki Area and Wuse Area links when click will display summary of all substations in those areas. 10. Further mouse over Garki Area and Wuse Area will display substations within those areas as illustrated below:
- 10. 11. So with a particular substation selected from the left navigation panel, a line diagram will be display in the main content sectionof the application. Example, in the line diagram above, the pilot substation Wuse II-2 was selected and corresponding line diagram is display with area maps within the diagrams. 12. Area maps in each line diagram representSATEC meters.When mouse over, display real time readings from the meters at a particular substation. In addition, when a particular substation is being view, you can use the top navigation bar to view real time data across all SATEC meters of a station. For example, Active Power is view across all meters in the pilot substation Wuse II-2 as shown below: 13. On the same view of a substation selected from the left navigation submenu, a onetime view of all SATEC meters from 11 and 33 KV can be view by clicking on the DATA POOL link from the top navigation menu on a substation line diagram page.
- 11. 14. When on the DATA POOL view page, it is developed to refresh at interval of 5 seconds.
