DL/T 657-2006 (English Version) PDF

Scope: This standard specifies the content and methods of acceptance testing of analog control systems in thermal power plants, as well as the quality indicators that should be achieved. This standard is applicable to the acceptance test of analog control systems at all stages of new construction projects and technical renovation projects of thermal power plants with unit capacities of 125MW to 600MW. The acceptance test of other capacity units and the acceptance test after unit overhaul can also be performed with reference to this standard.
