Integrated Monitoring and Control System Architecture for 11 kV Substation

It is essential to have an integrated system architecture for monitoring and controlling substation so as to ensure the safety of people and equipment. This paper presents an architectural design and technique that is used for monitoring and controlling 11 kV substation. The proposed architecture is based on the IEC 61850 standard and is designed to provide a safe and reliable system for real-time monitoring and control of substations. The design incorporates multiple substation communication protocols to create a completely digital substation. Primary and secondary devices are employed to reduce the number of potential failure points. Components are deployed to acquire data from various constituents within a switchgear board. This arrangement contains a process to manage older devices, wherein a data concentrator is utilized to communicate with other devices such as an intelligent electronic device. These are combined to collect and deliver the necessary data at the station level for different system users. Furthermore, the architecture is designed to be scalable and flexible, allowing for the integration of additional components and equipment. The results show that the proposed architecture can respond to remote IEC 61850 commands by above 90%.
