Emergency Preparedness & Operations Flashcards
Who does an RC need to notify if an EA is declared? Ho
All BA’s and TP’s in its area. Neigboring RC’s (via RCIS)
within 30 min of receiving notification
All EEA levels.
How long does an RC take to review Operating Plans?
No more than 30 days (sooner if urgent)
How much load is reduced for a given reduction in voltage?
5% voltage = 3% load
Who is responsible for maintaining emergency Operating Plans? What do the plans have to include? Who needs to review them?
TOPs and BA’s.
Roles & responsibilities for activating
Process to prepare for and mitigate emergencies.
How much time does a load reduction plan have to resolve a violation?
30 min
At what frequency should the last block of load trip in a UFLS scheme?
Above the generator UF protection relay trip level.
System restoration plans: how often must they be reviewed?
Annually
must also be updated to reflect changes & correct deficiencies
Where must system restoration plans be located?
In primary and backup control centers.
avail to all system operators
How often must a system restoration plan be verified that it accomplishes its intended function?
Every 5 years.
Who does the system restoration plan have to be coordinated with?
Neighboring systems.
How long does a TO have to submit reviesd SRP after unplanned, permanent BES change?
90 days.
for planned, revised plan approved before implementation
How often must blackstart resource testing be performed?
Every 3 years.
What does blackstart resource testing have to confirm?
- Avail gen & loads are controllable and operate w/in F and V limits
- Can meet real & reactive req’s of cranking path
- Supply initial cold start loads
What are training requirements for field personnel in system restoration?
same for blackstart resource training.
2 hours of training every 2 years.
Covers SRP, procedures for starting blackstart resource & engergizing bus.
How much time does GOP have to alert TO to changes in capabilities of blackstart resources?
24 hours.
How long does an RC have to resolve conflict with its restoration plan?
30 days
How much of the connected load should be shed to raise frequency ~1 Hz?
6-10%
What is the maximum block size for connecting load during restoration?
5% of online generation CAPACITY (not output)
What mode should AGC be on for an islanded situation
flat frequency
what lines are used to synchronize?
Highest voltage (low impedance, high relay capacity)
Describe isolating loads in blacked out areas?
CBs should be opened to isolate loads (on dist. system).
Automatic reclosing may need to be disabled.
What 3 values have to match on synchroscope?
Frequency, phase angle, voltage
What is max delta of phase angle for synchronizing
10%
How often does RC have to have system restoration training? (NOT drill)
Annually
RC system restoration drill requirements (NOT training)
2 per calendar year.
Once every 2 years, RC request each TO/GO ident. in SRP must participate in drill.
How often must RC review its restoration plan?
13 months
Backup CC plan - what is the required transition time?
2 hours or less
Backup CC plan - how often does it have to be tested?
Annually.
Backup CC plan - how long does backup functionality need to be maintained during test?
2 hours
When an RC makes a revision to its restoration plan, to whom must it be distributed and when?
TO’s and neighboring RC’s.
within 30 days
