Abstract: This paper focuses on the strategy applied in the gradual integration of a new data acquisition system with the online Plant Process Computer of the Laguna Verde Nuclear Power Plant. Due to the fact that the data acquisition modules needed to be replaced, the need for a New Acquisition System arose. The issue of whether or not to embark on a complete or modular replacement of its elements required careful consideration. At Laguna Verde, we opted for a phased migration approach, considering two main aspects: that the plant monitoring must remain online during the whole process, because it is required for plant operation and that human machine interfaces and computations design basis must be maintained, in order to minimize regulatory impact. The core of a phased migration strategy hinges on a flexible modular system capable of accepting data streams from multiple data acquisition systems and computers and consolidating this data for their presentation in control roo!
m displays and in the power plant historical archive. This paper describes the methodology that was applied to integrate the new data acquisition system into the legacy system, which is based on a real-time mechanism and historical data stream transfer.
Keywords: Data acquisition system, Gradual migration strategy, Historical archive synchronization, Obsolete plant process computer elements, Real-time external variables.
