Title: Power plant performance modeling: dynamic model evaluation. [Comparison of MMS and RETRAN codes]

Technical Report ·
OSTI ID:5242277

The dynamic performance of the turbine and feedwater train of a 550-MW oil-fired plant has been modeled by two modeling systems, the Modular Modeling System (MMS) and the Reactor Transient Analysis System (RETRAN). This report documents the performance of each modeling system and provides results on which the reader may be able to base a judgement as to the usefulness of each system for his modeling purposes. It compares transients simulated by the MMS with those recorded during tests conducted on an operating power plant. Specific information is provided on the type of model constructed, the agreement between blind predictions and measurements, and the level and type of modeling effort required together with computer run time. This program could not have been carried out without the willing support of the Boston Edison Company, which performed the transient tests on its Mystic Unit 7 and provided extensive engineering support to the program through the provision of detailed information on the power plant equipment and systems. It is believed that the insights into plant operation provided by the testing program itself resulted in more than sufficient improvement in plant efficiency to pay for the entire test program, but this could not have been foreseen by Boston Edison when they offered the plant for testing.
