This Bachelor’s thesis has been made for the research and development department at ABB Oy, Distribution Automation. The purpose of Distribution Automation products is to improve the safety, the reliability and the performance of the power distribution process. This sets high demands on product testing and verification. Integration testing is a part of the test process aimed at exposing the problems that arise from the combination of modules. The aim of this thesis work was to investigate the possibility to use SATEEN in the integration testing of protection relays. SATEEN stands for Substation Automation TEsting ENvironment and is originally designed for automated test execution in system-level testing. SATEEN is developed by ABB and only meant for internal use. Therefore there will be two versions of this Bachelor’s thesis, one for internal use only and one official version. The official version contains only theoretical information about substation automation including protection relays and product development. This Bachelor’s thesis resulted in a set of test cases that can be used for both integration and regression testing. Information about these test cases and the system under test will be presented only in the internal version of this Bachelor’s thesis.
