ASPEN动态模拟！！？ 各位朋友，这是怎么回事？ 当把aspen plus 静态模拟结果（已经收敛，并且符合pressure driven ）输入到aspen dynamic 中时，居然出现有的流股没连接上，但能进行动态运算，计算后出现这样的错误提示： ———————————————————————————————————————————————————————— torn group 1121 failed to solve due to failure of solution of sub-group 1 ———————————————————————————————————————————————————————— 这是怎么回事呢？查看更多
如何翻译:control strategies？ 楼上的朋友，你是仪表专业的吗？我是学化工工艺的。对控制系统了解的很少，可以继续向你请教吗？ 3.1.6.3 interlocks and safety instrumented systems the logic for safety instrumented systems is implemented in a high integrity trip system that is independent of the dcs. the system may be either a hard-wired or programmable system. if a programmable system is used, then the logic solver must be suitable for sil3 applications. this trip system should also provide essential indication of trip status . full indications of the status of the trip system and of the value of trip parameters are displayed on the dcs, inter-connected in a way that does not prejudice the reliability of the trip system. some safety-related trips have associated “tidy-up” routines to reset controllers; these routines are provided in the dcs. key-operated trip defeat switches are provided to allow testing of trip initiators as required. the status of the key defeats is displayed on the dcs. the logic of these trips is defined in the pbdp. 尤其是红色部分查看更多
