ISA 77.20.01 PDF

The scope of this standard is to address the simulation of fossil fuel power plants typically consisting of:

• Boiler, turbine, and balance of plant with steaming capacities of 200,000 lbs/hr (25 kg/s) or greater

• Combustion turbine or combined cycle combustion turbine capacity of greater than 100MWs

• Associated or interactive processes

This standard will address high-fidelity process and control logic models, highly replicated user interfaces, highly functional instructor tools, high-realism physical fidelity trainee environments, simulator platform considerations, and minimum levels of documentation.

Purpose

The purpose of this standard is to establish the functional requirements for several types of plant-specific, fossil fuel power plant control room simulators. It sets minimum criteria for the degree of software modeling detail and hardware replication, performance, and functional capabilities of the simulator control room operator interfaces. This standard does not address DCS tie-back simulators, or simulators used primarily for engineering purposes. 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.
