My NERC questions with correct answers

A misoperation occurred when an overhead ground wire on a 230KV transmission line between two substations broke and fell across A phase of the line. One of the line circuit breakers failed to open causing the breaker failure relay to pick up and as a result tripped the entire substation bus off line that the failed circuit breaker was feeding off of. Who is charged with the responsibility to develop procedures to ensure misoperations are reviewed and analyzed to determine proper mitigation plans? CORRECT ANSWER D. Regional Reliability Organization for the area. The transmission operator that you work for is installing new relays on some of their major transmission tie lines using newer technology. Who should your company notify before work is begun? CORRECT ANSWER C. Neighboring Transmission Operators, Balancing authorities, and Generator Operators. When shall the transmission Operators and balancing authorities review and update emergency plans? CORRECT ANSWER A. Annually When the responsible entity tags a dynamic schedule, what values should it use for the energy profile? CORRECT ANSWER Expected average MW profile for each hour. You are reliability coordinator in the eastern interconnection. Transmission Operator AB is in your Reliability Area. Transmission Operator AB reports that a 600 MW generator that tripped offline has caused an overload of a 345/138/13KV Inter-tie Transformer Bank. You realize that if the overloaded transformer trips off line, it would create an IROL. There are several Interchange Transactions that have parallel flows that are flowing through that transformer. What should you do? CORRECT ANSWER D. Issue a TLR on enough interchange transactions starting with the lowest priority and working up, until enough are curtailed to relieve the transformer from its overload condition.
