Because deh system can use feedback signal of the first class pressure as practical power of turbine , it can avoid the reverse control , have the good ability of anti - disturbing . by the sophisticate control logic deh can make swift change of the control demand for following best value according to the circumstance , largely improved the dynamic characteristic when the unit sundenly discharge the full load Deh系統(tǒng)控制器中的pid系數(shù)可根據(jù)試驗情況方便的調(diào)整,實現(xiàn)較好的動態(tài)特性,并可使調(diào)汽門動態(tài)過開,使再熱機組有良好的一次調(diào)頻能力; deh系統(tǒng)可采用調(diào)節(jié)級壓力做為汽輪機實發(fā)功率的反饋信號,避免出現(xiàn)反調(diào)現(xiàn)象,抗內(nèi)擾和外擾能力強。
