Along with gradually reducing of price difference between DCS and PLC
it makes the integration of DCS adopted control system in auxiliary workshops of power plants with the main machines to be possible.Taking 2×125 MW units in Shenhua Shangwan Thermal Power Plant as example
the structure
hardware allocation
and control range of the integrated control system of main-and-auxiliary machine in DCS have been presented.The practical application shows that the unitization of softwares and hardwares in the control system has avoided interfaces between DCS and hardware equipments
