IEC 61850 based high speed peer-to-peer communication called GOOSE (Generic Object Oriented Substation Event) has an impact on the development and testing of IEC 61850 relays and the associated protection schemes in modern power system. GOOSE not only provides an opportunity to optimize the system performance at reduced hardware cost but also eliminates various constraints in traditional protection schemes. Performance testing for GOOSE is an important item for the correctness and the real time performance of substation applications. The primary objective of this paper is to analyze the factors affecting the performance of GOOSE based protection schemes. The paper then discusses the methodology and advanced hardware and software tools available for performance measurement of lEC 61850 GOOSE.
