Download 20151112 SOTWG Item 08c TOP-09 R1 Tasks

System Operator Tasks - The tasks and required skills/knowledge (S/Ks) are listed but not the steps.
Task – Respond to a Remedial Action Scheme (RAS) operation
S/Ks:
1. Identify EMS screens used for monitoring a RAS
2. State SO responsibilities following operation of a RAS
3. For each Remedial Action Schemes (RAS) in the TOP footprint:
a. Describe how RASs are expected to detect predetermined BES conditions
b. Identify the RAS automatic corrective actions
Task – Respond to a Composite Protection System (relay scheme) operation
S/Ks
1. For each Composite Protection System (relay scheme) type in the TOP footprint:
a. Describe how the scheme is intended to operate
b. Describe how the scheme limits the severity and spread of disturbances
c. Describe how the scheme prevents possible damage to protected elements
From the TOP-009-1 Application Guidelines, dated October 6, 2015 (Draft 2) page 11, page 12
Solely having the ability to call upon a resource, such as a protection and control person, would not be an
example of having the knowledge intended by the standard because it confers a responsibility onto
personnel responsible for Reliable Operation.
For example, the knowledge and their effects on the BES may include, but are not limited to, the
following items:
 Composite Protection System and RAS intended function
 Composite Protection System and RAS operates as intended
 Composite Protection System and RAS failure to operate as intended
 Composite Protection System and RAS unintended operation
From the NERC Glossary of Terms dated September 29, 2015
Composite Protection System (Becomes effective 7/1/2016)
The total complement of Protection System(s) that function collectively to protect an Element.
Backup protection provided by a different Element’s Protection System(s) is excluded.
Element
Any electrical device with terminals that may be connected to other electrical devices such as a
generator, transformer, circuit breaker, bus section, or transmission line. An element may be
comprised of one or more components.
Protection System
 Protective relays which respond to electrical quantities,
 Communications systems necessary for correct operation of protective functions
 Voltage and current sensing devices providing inputs to protective relays,
 Station dc supply associated with protective functions (including station batteries, battery
chargers, and non-battery-based dc supply), and
 Control circuitry associated with protective functions through the trip coil(s) of the circuit
breakers or other interrupting devices.
