Current utility practice for relay testing is to use portable test-sets capable of generating steady-state test waveforms. Recent studies, however, have indicated that steady-state tests are not sufficient if the full behavior of a relay is to be evaluated. Digital simulator concept is one of the most desirable solutions to this problem. It includes hardware and software that allow both phasor and transient testing of protective relays. This paper describes relay testing and signal processing software for a newly developed two-terminal digital simulator. The simulator development was initiated in late 1989 and has resulted in several modeling and simulation studies, as well as simulator hardware and software designs. The software discussed in this paper was installed for beta-site testing at the department of Energy--Western Area Power Administration (WAPA) in the Summer of 1995. It has also been extensively evaluated at Texas A and M University, with the close cooperation of Houston Light and Power Company (HL and P). This software is capable of performing data conversion, signal processing, signal analysis, relay testing, and test result analysis using various transient data formats such as COMTRADE (IEEE COMmon format for TRAnsient Data Exchange), electromagnetic transient program (EMTP), and digital fault recorder (DFR). In this paper, the digital simulator hardware configuration is presented first. The software requirement and software configuration are discussed then. Next, the new software developments are described. Examples of the software applications are also outlined.
