This technical report defines test procedures, data collection requirements and data analysis methods for determining and reporting the dynamic performance of control systems for boiler and turbine control systems on generating units with a rated capacity of 25 MW or greater or a boiler steam flow greater than 25 kg/s (200,000 lb/hr). This technical report covers aspects of dynamic plant operation including constant load operation, normal load ramping operation, grid regulation operation, and response to frequency upset, load runback, and load rundown operation. The purpose of this technical report is to establish dynamic performance criteria for power plant control systems by specifying a consistent means of evaluating control system performance necessary to comply with contractual specifications and other dynamic performance requirements.
