A preprocessing block with two different task times isavailable. All the function blocks functioning at 3 ms task time must be connectedwith a preprocessor operating at 3 ms. Similarly, all the function blocks functioning at10 ms task time must be connected with a preprocessor operating at 10 ms.The preprocessor calculates various quantities based on an adaptive DFT. Theadaptive DFT requires a reference frequency for performing calculations. In thisconfiguration, the voltage signals are taken as reference for calculating various phase-side and neutral-side current quantities.See the technical manual for details on frequency adaptive.A fixed signal block providing logical TRUE and FALSE output is used, andconnected internally to other functional blocks as needed.3.2.5 Control functions3.2.5.1 Generator bay control QCCBAYBay control is used for handling the selection of the operator place per bay. It providesblocking functions that can be distributed to different apparatus within a bay. Baycontrol sends information about the PSTO and blocking conditions to other functionswithin the bay, such as to switch control functions.Section 3 1MRS757582 CREG630 variants28 REG630Application Manual
