Automatic simulation of IED measurements for substation data integration studies

With the deregulation and restructuring of utility industry, many substation automation applications are being developed. These applications need to be tested for their accuracy and reliability. In cases when physical testing in substations is difficult, it is desirable to have a software tool to simulate the intelligent electronic device (IED) measurements in substations. This paper presents the design of such a software application that can be used to generate substation IED measurements in fault and/or switching scenarios. The software structure and input/output interfaces are provided, as well as their implementation details. Two examples of simulation results are included in the paper. This software application serves as a handy tool for substation automation related studies.
