General and role-specific logging procedures can be found in whatoperating order?
SOO 1T-07 (Logging Procedures)
What must a Load Operator first do upon assuming PIC duties?
Sign their name on the Paper Based Log
When is a Switching Order required?
When there are three or more switching steps issued simultaneously
The Switching Order procedure is defined in what operating order?
1T-06 (Switching Procedures, Designated Isolation Point and Equipment Not Ready for Service)
Where are the definitions, rules, and procedures pertaining to SafetyProtection Guarantees found?
In the Safety Practice Regulations (SPRs) under Section 600 (Isolation and Tag Out: T & D)
In addition to recording the issue of a Safety Protection Guarantee withan SPG card, what additional logging must take place?
The SPG is recorded on the paper desk log:
-SPG Number, designation of lines or equipment, time & date, permit holder, CROW number
What is the purpose of POCC?
The electronic PSSP mimic display used by Load Desks to mimic Level 4 main trunk of the distribution system outside of the substation fence
-POCC is a static display that is maintained manually by operators
-replaced the old wall boards from previous control centres
What operating order describes the guidelines for using and updatingPOCC?
DOO 1D-52 (POCC)
What operating order describes specifically how POCC is to be used asa mimic display?
DOO 1D-06 (Distribution Mimic Displays)
How are reclosers and SCADA switches displayed in POCC and why?
They are represented as a ‘blue’ device
-a ‘blue’ device indicates that the device status must be verified in AREVA
What does the “L” symbol displayed in the POCC Schematic Windowrepresent?
‘L’ indicates presence of a Loop to warn of the possibility of back feed when isolating a portion of a feeder’s main trunk
-Loop status is not mimicked in POCC (nor should POCC be relied upon to identify the presence of all Loops)
What is a composite schematic?
Composite schematics display multiple feeders on the same schematic
- The operator can easily trace between circuits when switching involves more than one feeder
Why is the POCC Geographic Window not used for operating in realtime?
There are delays in the PA (Plant Alteration) process to post updates to GIS (Geographic Information System) (The system that provides the geographic feature in POCC)
-Thus, Geographic can not be trusted in real time
How can updates be made to POCC schematics in real time? What isthe preferred method of updating a POCC schematic?
Schematics can be updated in real time by selecting the ‘Maintain’ feature, making edits under a ‘Pending’ schematic, and ‘approve pending’ when the operator is satisfied that the mimic is an accurate representation of the electrical system
The preferred method of updating a POCC schematic is electronically with the editing and redline tools
Generally speaking, what is the purpose of the CROW application?
A communication tool used by the control centre and field staff:
-Control Centre: CROW Client is used for Outage/Permit scheduling, Operations logging, Notifications, Reporting
-Field Staff: CROW Web is used by field staff for maintenance planning, requesting permits, request planned outages
What line of operating orders are the CROW guidelines described in?
SOO 1T-54A, SOO 1T-54B, SOO 1T-54C, SOO 1T-54D
What are the four different browsers within CROW?
1. Outage Requests
3. Permit Requests
4. Station/ Field Reclosing
What is a CROW Outage Request?
A formal process by which planned scheduled outage work is evaluated and approved for implementation
-Outage requests are submitted for review and approval by control centres, operating entities, and resource planners
-The Outage Request Form (ORF) is used to log planned outages as CROW events
-‘Approved’ outages : Outage request browser color is purple
What must be done in CROW when an approved Outage Request istaken?
The operator will ‘Implement Outage’ by selecting the ‘Implement Outage’ button
This moves the CROW Outage Request from ‘Approved’ to ‘Implemented’
-Outage request browser changes color to green
When should an implemented Outage Request in CROW becompleted?
When an ‘Implemented’ request is returned (by field staff), the operator will ‘Complete’ the request by selecting the ‘Complete Outage’ button
-Outage request browser changes color to black
What events are logged in the CROW Events Browser?
What events are logged in CROW as Forced Outages?
-Events involving station equipment
-Outage events involving sustained distribution feeder outages and associated equipment(But not Momentary Outages)
-Events involving Bulk customers that connect to the distribution system
-Events involving IPP generating units larger than 20 MW connected to the distribution system
What is the general purpose for logging Forced Outages in CROW?
-to capture availability/ unavailability of equipment and circuits
-to record significant operating reconfigurations that impact reliability
-to record customer impacts
-to record SDR data
What are Parent and Related Outages?
The Parent outage would be an outage closer to the source (ie substation distribution bus)
The Related outages would be outages downstream of the Parent Outage (ie associated feeders)
-In CROW, there is the ability to link Parent outages to Related Outages using the ‘Related Events’ tab
Why are Carried Bys logged in CROW?
To provide a means of logging abnormal feeder configurations
-they can easily be filtered and viewed by desk
A new ‘Carried By’ entry for a feeder will cause any approved permits to become unapproved
-the operator will be required to reresearch permits to ensure proper reclosing has been turned off
When a ‘Carried By’ is returned, the same process occurs: CROW kicks out permits to be reresearched
What is an Unusual Condition?
A change from the normal state or condition of equipment, that impacts the operation of the system or system equipment, where it is expected to be returned to normal in the near future
What operating order describes alarm handling and the criteria forentering alarms in CROW?
1T-54B (CROW Event Processing)
How are AREVA analog alarms that are nuisance or may indicatefailure of equipment entered into CROW?
They are logged in CROW as ‘EMS/SCADA’ events, which will be assigned and dealt with by the EMS help desk
What is the purpose of the Permit Requests Browser (P3)?
The Permit Requests Browser allows Field Operations personnel to submit permit requests to the control centre (through CROW Web)
-permit requests can also be made verbally, by fax, or by e-mail, where the operator will then create a new ‘Permit’ Request
What is the purpose of the Reclosing Browser?
Purpose is to request a Non-supervisory recloser be opened/ closed as required by sending notification to the field manager via CROW
What areas of the province use the Reclosing Browser?
Only used on Load Desk 4&5 now (Vancouver Island)
Every night, after the day’s permit requests have been processed, whatmanual task must be performed by the Load Operator and why?
The Operator will sort through the ‘Reclosing Browser’ and update the Reclosing On/Off as required
This will determine if the device needs to be turned on or off for the next day, so that field crews can be notified
What operating drawings are produced by DAD for use in the controlroom?
- Distribution Operating Diagram (DOD)
- Underground Distribution Diagram (UDD)
- Primary Maps (PY)
What is the purpose of the “Yellow Sheet Check” performed by theLoad Operator?
-to check that a PA has been correctly updated on DAD and matches the red mark up on the print
-to compare a new print against the current print to make sure the new one is correct
