Thermal stress control system actually gather the real - time data of unit sets , compute temperature fields , stress fields and maximum dangerous stress by the math modal , decide target and speedup rotation in every stage of startup process , and justify automatically to realize auto control a serial of processes of turbine , such as speedup , warm - up , connecting net , load changing , stop and unsteady condition etc , and improve automatic level of the unit sets. turbine auto startup ( tas ) system can automatically evaluate steam turbine ' s startup and load changing process according to thermal stress of
熱應力控制系統實際是對機組運行參數進行實時採集與監控,通過數學模型實時地計算高、中壓缸轉子的溫度場、應力場分佈,以及最危險熱應力,以確定啟動過程各階段的目標轉數及升速率,並進行自動調整,實現機組沖轉、升速、暖機、並網、升負荷、停機以及異常工況下的自動控制,大大提高了機組的自動化水平。 -
Abstract : based on the operation data, the cold start - up and warm start - up curves of a czecho 200 mw steam turbine are worked out according to the operation rules ; the fem calculating models of the temperature field and stress field of the high pressure rotor are established, and the suitable boundary conditions are given ; the temperature field and stress field of the high pressure rotor are calculated and analysized during these two working situation
文摘:在現場實測數據的基礎上,根據運行規程擬定捷制200mw機組的冷態啟動和溫態啟動曲線;建立高壓轉子溫度場和應力場有限元計算模型,確定相應的邊界條件;計算分析在這兩種工況下高壓轉子的溫度場和熱應力場。
