abstract
A variety of digital power system simulator solutions have been implemented and used by utilities, universities and relay vendors since it was first introduced in the late 1970's. A new concept for a modular digital simulator design, which utilizes a variety of hardware and software modules, has been developed and used to configure different simulator solutions. This flexible implementation approach is aimed at meeting specific needs for relay testing and simulator upgrading. It also provides a choice between low and high cost simulator design options, depending on the performance and application requirements.
