SI Flashcards
(8 cards)
Your department manager informs you about an executive complaint. To start collecting data about the complaint, a troubleshooter has to be sent out to take load and voltage readings. This is a time sensitive request. You approach the desk and request a crew for this assignment. The desk responds that everyone is busy and they will let you know when someone becomes available. What is your response?
- Vet it out and understand it myself. Research the history of the event. Potentially speak with engineering. Next, Explain the situation and why it is sensitive.
- Ask about and review what current jobs are going on. See when the next crew will be available, estimated job completion. Make sure it’s a crew that makes sense for the task at hand.
- Reiterate the importance of this complaint and sensitivity and explore re-prioritization options. See if it makes sense or is possible to a pull a crew or T/S from a job.
- Ask the desk for ideas to resolve the issue and come to a mutually agreeable compromise, reiterating that safety and customer experience are overarching company goals.
- Consider alternatives (such as sending a supervisor to “show face” and speak with customer)
Describe feeder processing for a 33kV feeder O/A. What are the differences between and O/A and scheduled job?
O/A Process:
Feeder O/As at FKs or FHs
1 Dispatch supervisor & troubleshooter to patrol the feeder. & FOD to unit stations
2 FOD to clear stations: check bank breaker open, auto reclose set to off, rack out the breaker and transfer the L&P, remove L&P fuse and remove sec PT fuse
3 T/S & supervisor to visually inspect Fdr & check fault indicators. SM will check PQ nodes
4 FOD to clear HTVs (high tension customers), check breaker open & stop tag.
5 FOD to isolate ATS if on fdr
6 T/S to check open all OH tie sws, install stop tag, block open tie sws
7 Apply portable grounds in station Fks or FHs, feeder ground, open fdr shunt reactors (cause they can act as ground)
8 FOD to FKs/FHs with high pot truck, high pot feeder. If it fails use CAP discharge to locate fault. (HV) - every 6 seconds and it’ll blow.
9 When fault is found, shut down HV and reground the feeder, inspect the fault. And location of fault is communicated to DO via rapid restore and a phone call.
10 FOD to then install target grounds (1st location past fault - such as pole, TX, etc.)
11 Apply IATC to fder. Once verified with TC and FOD marks FDR ID & phase, install certification tag. Then its reported to the DO
12 So once you shut down the IATC, reground the feeder and apply protective grounds closest to fault location.
13 Then feeder is ready for work and DO gives the feeder to the regional control center shift manager.
14 Then once work is complete, fdr returned to the SM and then to the Do. All protective grounds removed and station performs ammeter clear test and FOD performs high pot.
15 Close reactor & cut in fder. (verify phases if copper was broken)
16 Send FOD to restore Unit substations, HTVs, and Ats
17 Sent trouble shooter to pull stop tags
O/A
O/A does not have deload moves first, isolate after O/A
No checking for open networks? Substation operators verify DBF that before it gets to FOD
Sched
Deload before outage
No fault locating
Describe Staten Island ICS levels and what do you think your role and responsibility as the day manager during ICS and planning for ICS.
Planning:
Obtain weather forecast & attend interregional calls
10 Forecast - Temp Variable Levels and load (for heat) or check predicted impact and classification level for OH storm or winter UG event
Consult ERP / Classification
Review Matrix / Staffing
Review any spec changes and communicate updates
Ensure staffing on each desk
ICS Notification - Notify when ICS is happening
Place STAR into storm mode - ETR on dispatch or Manual
ICS Structure has to be filled
Site Safety
Outer borough support
Review # of generators
SHIFT MANAGER CAN FILL IN OR OTHER DESKS
If it’s a heat event: Review summer prep specification - voltage reduction, DLRP, EO 4095
Ensure appropriate FOD levels to meet feeder processing goals
Staging people at the right areas for the next moves
Ensure cooling kits available for networks
make sure that materials such as dry ice is available
Unit stations to turn on fans / spray
If it’s a OH storm: focus on OH troubleshooters and OH crew levels
Consider the need for mutual aid and latter line crews
Staff up damage assessors
For coastal storm you might need sand banks for substations
And consider putting the system in 1 trip to lock on the reclosers to prevent harm to the public/employees
For an UG event:
focus on sufficient UG crewing
activate the manhole response team
and ensure materials such as shunt boards and snow clearance
During ICS:
Fill ICS position - typically planning chief in the bubble
Ensure communication and continuity between shifts and departments - do an update / handoff to next planning chief
Provide the IC with status of contingencies, contingency analysis, and proposed solutions
Plan, prioritize, monitor, and communicate restoration plans
Monitor incident goals such as PSCs, scorecard, ETRs
Monitor customer outages, customers restored, number of jobs dispatched..
Communicate priority of jobs
Communicate to the situation room and CERC
Adjust crewing and staffing as necessary
Use voltage reduction if necessary
What do you view as the most important specification or procedure to the CC? How do you communicate it to the control center of any spec updates or procedure changes?
The hipot spec is updated, how do you go about communicating that update to the operators on the desk?
EO-4095 - Operating under contingency conditions
ERP - Emergency response plans for All types of events - provides guidance and classifications and notification and response
Blue Book - General instructions governing work on system electrical equipment - UG
Green Book - OH operating
CI-260-2 - Corproate instruction on incident reporting
Have a good understanding of the change
Understand the before and the after and the why
Due to different shifts its difficult to get everyone in the room to explain changes
Target shifts and explain to CC folks the updates at each shift
Have SME in the room when possible to help explain, clarify, answer questions
Set up training if it’s needed
Solicit feedback
Communicate through email with summary of new procedures/updates
Provide everyone copy of new update and highlight specific portions that are changed from before
What tools or methods would you implement to prevent an operating error or incident?
Communicate regularly, engaging employees, promote cross-training (reduces complaceny) Good practice for a SM to interact with employees at beginning of shift make sure eveyrone is in the right mindset HPI Tools Self check peer check 3 way communication 2 minute rule procedural adherence time-out procedure
Ensure documentation is correct
Periodic spec & procedure review
Look for process improvements
Leveraging technology - GIS, AMI, SCADA, Iphones
Describe the Staten Island system in detail. What do you know about reclosers & unit substations? Jurisdiction?
1st contingency system
Freshkills 138kV and Fox Hills 138 kV feeds the 3 Ws = Wainwright, Willowbrook and Woodrow 13 kV substations
TXs going from FKs stepping down to FKs 33kV to feed the 33Rs and high tension customers like Pratt, Seaview hospital, and the college of SI
The FK 33Rs supply the unit susbtations on our 1051 4kV grid
Fox Hills 138 kV feeds 33kV Fox Hills which also feeds 33Rs and high tension customers like the staten island hospital
The 33Rs from FHs feed the 1050 4KV grid
Then you have the autoloops that come out of FKs 33, FHs 33 and the 3Ws
The autoloops are the 1Rs, 2Rs, 3Rs, 4Rs, and 5Rs
They are mostly 5 recloser autoloops but there are some 7s - so they are made up of 2 distribution feeders, feeder reclosers, midpoint reclosers, and an normally open tie recloser that are meant to maintain power to as many customers as possible by isolating a faulted section.
Then you have your URD system that’s fed by the OH 4KV and 13kV
We have 5 4kV grids the largest one having 12 USS and the smallest 1 with three which always makes it a little nerve racking when we lose one feed
The USSs have 4-5 feeders coming out of each bus and interconnecting to the others in the grid. Connected via a normally closed GTSTS = Grid Tie Single Triple Single or GTTS. Between the grid ties and the stations there are grid mid sts or grid mid ts’s.
We also have multi bank installations like those at seaside, naughton, terrace
And a couple of 13 kv and 4kV mini loops
Operationally, with the 13kV autoloops they do help minimize customer outages however they do see more flickers, with the 4kV grid the customer usually does not know about any outages and it is more reliable, usually our main concern with the 4kV grid is possible low voltage conditions.
Jurisdiction
33kV DO
13kV After backfeed switch
4kV after secondary bank bkr
Can you describe a few performance metrics that relate to customer excellence and how would you ensure we meet the goals?
SAIFI - 226 CAIDI - 1.19 ETR - 73% company vs. goal of 70% Feeder Processing CRM - customer relations management - customer satisfaction
reviewing PSC reporting
finding patters and areas of improvement,
understanding how KPIs are calculated,
sharing it with operating groups and reinforceing expectations;
understanding ETR rules
For feeder processing - staging for next steps
Ensure we address CRMs in a timely fashion
Who are your customers as the Day Manager and how do you coordinate and work with the customers?
Probe: Construction and the control center has different priorities and views on the feeder scheduling process. How do you align them together?
Coordinating between different groups, levels, wants and needs is what I do now on an everyday basis.
At the end of the meeting send out meeting notes and next steps.
