Description
For the utility system of 2 units, such as the plant utility and standby power system, as with the thermal control system
, the configuration of DCS enables the operator of the other unit to monitor the utility system when the unit is stopped,
and requires reliable measures to ensure the uniformity of its control commands. That is, only one DCS system is allo
ed to control the public equipment at the same time. The DCS sugar of 2 units cannot be combined because of the exist
ence of a common system.
According to the characteristics of DCS, two typical methods are used to control the common system in practical engineerin
g application. The DCS of Jiujiang Phase III is the HIACS7000 system produced by HITACHI Company. In the configuration
of DCS, we configured the same hardware and software in two units to realize the conversion of operation rights by switchi
ng switches. The signal of the external device is fed into the two DS systems by several configurations (analog) or by exten
ded conversion (switching). At the same time, to ensure that there is no misoperation accident, but also increased a considerable
part of the criterion conditions and 1/0 test point, the advantage of this method is that when a unit is out of service or maintenance, it ca
n be more convenient to check the DCS, but also increase the reliability of the control, the disadvantage is to increase the numb
er of external equipment, increase the cost. Adding a link also means increasing the possibility of the occurrence of the past. The
DCS of Xingui Yidang is the -90 system provided by Bae Company, which uses a human ring to check the system junction, and t
he control of the common system is realized through the common ring configuration. Two sets of DCS are controlled by Tagnum
ber, which better solves the problem of precision
