PMU Interoperability, Steady-State and Dynamic Performance Tests

To ensure the performance of a synchronized phasor measurement system (SPMS) to be deployed for the Brazilian interconnected national transmission network compliant to the specific SPMS requirements, Operador Nacional do Sistema Elétrico (ONS) of Brazil has completed a phasor measurement unit (PMU) certification test as the first step of its PMU certification process for the SPMS. PMUs from eight vendors were selected and tested in this project according to a comprehensive test program specifically developed for this certification project, which is based primarily on the IEEE C37.118-2005 standard as well as the specific requirements of SPMS and its applications. This paper presents and discusses the general background information, the developed test program, the test unit selection and the testing processes, and the overall test results of this project.
