Why we should send information to higher level operation centers or why we should model IHMI Loc, LLNO Loc or XCBR Loc
IED Local/Remote (and Station level Local/Remote) switches (HW or SW related) are possible barriers for unwanted operations and gives information to higher level operating centers about operation capabilities.
- An IED L/R switch itself is not enough to secure the work on the primary equipment, but informs higher level operation centers about that work is going on.
- A forgotten L/R switch may of cource by the same reason stop a wanted operation in case of breaker fall etc.
The higher level operators have a big problem if swithes is forgotten in wrong possition after finished planned work.
Continue the discussion about how to model a common concept for Station level, Bay leval and process level implementation of authorisation information.
There is a need to be able to model Emergency level, Backup level, Local, Remote, several levels of Allowed centers.
A simple Loc on Bay level informs next level about if it's possible to operate or not a detailed llevel information may be include as proposed in an additional INS/INC.
