In view of results obtained in the work, the commonly 共同 made assumption 假定 of equality 均等 of heat transfer coefficients for both the bundle and its additional surface may lead to certain 確定 errors 誤差 in heat transfer calculations and discrepancies between the calculated values of heating surfaces area and later operational needs of steam generator
在工作得到的結果，傳熱系數的做法為捆綁和它附加的表面在熱傳遞演算也許導致某些熱化表面的誤差值和蒸汽發電器之間的錯誤和差誤。 -
This article emphatically discussed and analyzed following points : load command feed forward function can improve the rapid respond character of steam turbine generator ; lead of load command have advance control function on boiler main control and can highly improve the stability of main steam pressure ; the use of predict control and state space variable function can improve the quality of boiler steam temperature control effectively, control the steam temperature in the defined range and increase the boiler and turbine life and efficiency even if working state changed in a big range ; linear compensation can restrain the vibration of generator load in the condition of big loa d change
本文重點討論、分析提出負荷指令前饋作用可以提高汽輪發電機快速響應特性；負荷指令的導前功能對鍋爐主控有超前控製作用，能顯著提高主蒸汽壓力的穩定性；採用預測及狀態空間法能有效改進鍋爐蒸汽溫度控製品質，在大幅度工況變化下仍有效控制蒸汽溫度在額定范圍內，提高鍋爐、汽輪機壽命及其效率；汽輪發電機組的快速響應性與汽輪發電機組負荷振蕩問題間的平衡關系，採用線性補償可以有效抑制在負荷變化梯度較大情況下發電機負荷振蕩問題。
