Alarm Processing Approach – Expected Delivery Schedule
When frequency deviation is above the RRS recovery limits
When RRS is deployed partially and frequency deviation above RRS limit
If the real time frequency is above defined threshold
When reserve capacity is below Operator specified limits
When un-deployed regulation-up is below Operator entered threshold
When un-deployed regulation-down is below Operator entered threshold
When telemetered HSL is higher than Net Dependable Capability
When difference between HASL and total energy req < Operator threshold
When the difference between HDL sum and total energy req < Operator threshold
If scheduled LAAR and RT LAAR are differed by threshold
Need to send selected alarms to MIS
When SOL is more than 95% of the limit specified
When MVA line or trans flow > 98% dynamic emer rating or 100% normal rating
When RT flow close to 95% of SPS triggering condition
If real time status of SPS goes disabled, alarms shall be generated
When 345Kv bus voltages are outside specified limits
When 138/69 Kv bus voltages are outside specified limits
When RE (Resource Error) is outside the limits defined by the Operator

5.
6.

8.
EMS Hardware insufficient for user base and functionality
– INF prioritized production hardware for EMS – will use for EMS 3B
SCADA mapping resulted in all Combined Cycles MW telemetry levels set to 0
– Corrected in SCADA load on Friday 12/14; still needs to be verified
Interface table for Constraint Names incorrect so SCED is not able to process
constraint names & shift factors
MPs sending Incorrect values for CC configuration causes SCED failure
– Working with EMS team to implement data check and MPs to send valid
configuration values
MPs sending HSL < LSL resulting in SCED failure
– Working with MPs to resolve and adding validation in EMS to set LSL = HSL
when telemeter HSL<LSL
MPs sending resource status of off when actual telemeter MW output is > 0
– SCED sets basepoint = 0
MPs sending invalid resource status (e.g. 050)
– SCED ignores the unit
DC TIE Telemetry missing and DC Tie calculation not working
– Adding telemetry and EMS team resolving calculation function
Joint effort between ERCOT and MPs to resolve most of these will enable
reasonableness declaration
