PEA SCADA Online Monitoring

Abstract—A trend of the electric power enterprise construction will be the online monitoring, but the PEA SCADA system cannot monitor from outside by web browser or internet because PEA’s SCADA system in some areas is also a centralized computing system that is not designed to interface or monitor with external systems. Normally, the SCADA system in such area should be renovated or upgrade to a network computing system but requires a very high investment. For this reason, we try to use the existing system and develop an online monitoring applied to the problem of the centralized computing system. This paper presents a solution for SCADA substation online monitoring, an online monitoring architecture for the SCADA system to support smart grid, and presents a concept of online monitoring and network virtualization for this system. The aim of this approach is to propose an architecture of SCADA online monitoring that ensures access, available, flexible and consistent for PEA SCADA online monitoring. This paper discussed the feasibility study of handling of monitoring of unmanned substation on internet framework retaining smart grid security in Thailand. The monitoring of the device status and analog value of substation can also be done from the network through cloud-based SCADA with the online monitoring using internet connection. The assessment results allow the network administrator to plan infrastructure expansion with confidence in the security and reliability of the network's operation.

Index Terms—Online monitoring, SCADA, substation.
