Description
Overview
The DS215TCEAG1BZZ01A Emergency Overspeed Board is a GE Mark V protection module designed to provide high‑integrity overspeed detection, flame monitoring, and synchronization support within turbine control systems. Operating as part of the protective processor group, the board contributes to fast, deterministic trip decisions during abnormal turbine speed conditions.
Functional Characteristics
This module exchanges real‑time data with the X, Y, and Z processor cores, forwarding processed information to the R1 core through the IONET communication network. Median‑value selection is performed at the R1 core to ensure accurate and noise‑immune decision‑making.
The DS215TCEAG1BZZ01A manages emergency trip outputs by driving relay signals that are evaluated by the TCTG module using voting logic. Integrated diagnostics, onboard power regulation, and configurable hardware jumpers allow customization of overspeed thresholds, IONET addressing, and stall‑timer behavior.
Flame Detection and Synchronization
The board processes ultraviolet flame detector signals, applying internal scaling and validation algorithms before forwarding the data to the CSP processor. These inputs support safe turbine operation and combustion monitoring.
For synchronization, the module evaluates generator voltage and frequency conditions. Breaker‑close permission is issued only when system parameters fall within acceptable limits, ensuring safe and controlled synchronization events.
