An electrical substation refers to a station of power generation, transmission and distribution systems where voltage is transformed either from high to low or from low to high using step-down and step-up transformers respectively. Substation automation means utilizing the data from the Intelligent Electronic Devices (IED's) for the control and automation functionalities inside the substation, based on the control commands that it receives from remote users to control power system devices. The end user’s control the devices by the applications. These applications will have to undergo many tests to achieve more productivity. WHMI is one such web application which can be used to check the functionality of the IED using the web. WHMI automation is used to automate the continuous testing tasks of the WHMI application which is hard to do manually. To perform the automation a free-ware open source Robot Framework tool is used which uses the python coding. This technique is based upon finding for keywords in the test suite that describes actions to be performed on the target and calling functions associated with those keywords. Using keyword-driven approach, reusability of automated test cases can be improved. The effectiveness and efficiency of testing can be increased with the help of test automation. The results are compared with manual testing and the performance is analyzed.

Keywords—Protection and Control IED manager (PCM), Intelligent Electrical Device (IED), Web Human Machine Interface (WHMI) and Robot Framework.
