本報告では、HTTRガスタービンコジェネレーションプラント(HTTR-GT/H plant)のシステム性能評価を行った。具体的には、起動停止及び負荷追従運転時の運転制御性について検討を行った。また、負荷喪失時や水素製造施設異常時の制御特性評価を行った。性能評価結果から、HTTR-GT/Hプラントにより実用高温ガス炉の運転制御法の確証する試験の実施が可能であることを示した。

This paper presents the system performance evaluation for HTTR gas turbine cogeneration test plant (HTTR-GT/H plant) so as to confirm that the design meets the requirements with respect to the demonstration test objective. Start-up and shut down operation sequences as well as operability of load following operation were investigated. In addition, system dynamic and control analyses for the test plant in the events of loss of generator load and upset of H plant were performed. The simulation results presented in the paper show that the test plant is suitable for the test bed to validate control schemes against postulated transients in the GTHTR300C. The results also lead us to the conclusion that HTTR-GT/H plant can be used to test operational procedures unique to HTGR direct-cycle gas turbine cogeneration.
