One of our GE frame 6B gas turbine MarkV control started inaccurate counting (maybe from 2015) just after reboot R, S and T controller at the same time. Inaccurate parameters are:
1. Total Active Energy (for example: it counts 0.1MWH instead of 35MWH within 1hr)
2. Total Reactive Energy LEAD
3. Total Reactive Energy LAG
4. Total Gas Fuel Flow
During last outage on January 2018, I downloaded "ALL" to r, s and t controllers with corrected (by GE) TOTD_Q, but there is no change. Is this a hardware issue, RAM or EEPROM? Other than that the turbine is running fine. All controllers having A7 status right now.
