САЖЕТАК / ABSTRACT:
Currently, in ROSC methodology RAs are based on analysis calculated prior to the real time, on a model prepared in day ahead or intraday time frame. This implies that RAs that are agreed in day ahead or even intraday may not be applicable to the real time operation, due to unexpected changes in the system. In such cases, the agreed RAs must be reconsidered or even new RAs must be defined in a very short period of time. This is only possible if RAs selection is automated. This mechanism can also be used when defining so-called fast RAs according to the ROSC methodology (presently, qualitative, based on personal experience, criterion is used instead of numerical when defining fast RAs). With automated RAs, the resilience of the system could be greatly increased in the most demanding situations. RAs can be:
- Preventive (PRA) which is by the definition from ROSC methodology a RA that is the result of an operational planning process and needs to be activated prior to the investigated timeframe for compliance with the “N-1” criterion.
- Curative (CRA) which is by the definition from ROSC methodology a RA that is the result of an operational planning process and is activated straight subsequent to the occurrence of the respective contingency for compliance with the “N-1” criterion, taking into account transitory admissible overloads and their accepted duration.
This paper will show the way to automate the selection of remedial actions as well as their execution by automatically sending group signals from the SCADA system to the primary equipment. The signals that are exchanged can be signals for changing the state of the switchgear or signals for changing the positions on the tap-changer transformers or the power on the generator units. Also, the paper will describe the software implementation of the RA tool and the way of its integration with the SCADA/EMS system and application bases of the EMS system.
