Xinyang Phase I and Yiyang Phase I are INFI-90 system provided by Bailey Company. Common ring is adopted for its system structure, and the control of the common system is achieved through the configuration of common ring. Two sets of DCS are controlled by Tagnumber, which solves the coupling problem better. The advantage of this control mode is less configuration, external devices do not need to increase, and the effective use of information resources; The disadvantage is that the equipment of the common ring can not be repaired without power failure, unless the two units are stopped for maintenance, which aggravates the requirements of the safety of the equipment operation.
7DCS input and plant power supply period
Plant power control into DCS, because there is no independent of DCS hard hand operation, and according to the previous power plant construction experience, in the back power plant, DCS has not been put into
operation, at this time high voltage start/standby change, high/low voltage plant power operation can not be achieved, so DCS equipment installation, commissioning and operation in the period to cooperate. In the plant power equipment installation and debugging at
