ISA 77.20 PDF

This standard establishes the functional requirements for several types of fossil-fuel power plant control room simulators primarily used for operator training. It sets criteria for the degree of hardware replication and software modeling detail, performance, and functional capabilities of the simulated control room instrumentation. This standard does not completely address standalone DCS-based trainers/simulators, nor simulators used for engineering or test purposes such as part-task training devices intended for specialized training. This standard does not establish criteria for the use of simulators in training programs.

Operating and training practices and procedures differ considerably among the various organizations that operate fossil-fuel plant control room simulators; however, the goals of personnel safety, maximum equipment availability and lifetime, and efficiency of operations are common to all. Therefore, this standard is intended to provide flexibility in both design and use.
