| Abstract: | Deviation causes of main steam flow value indicated in DAS system for Xiangtan power plant unit 1 and unit 2 are analyzed in this paper and problems existing in the original calculation model are found.A new relationship between main steam flow and other parameters such as pressure after regulating stage is established after comparing main steam flow of performance test and the main steam flow value in DAS system.Finally,modification suggestion of original calculation model is presented. |
