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系统控制器中的pid系数可根据试验情况方便的调整,实现较好的动态特性,并可使调汽门动态过开,使再热机组有良好的一次调频能力; deh系统可采用调节级压力做为汽轮机实发功率的反馈信号,避免出现反调现象,抗内扰和外扰能力强。
