Konexa's Digital Grid Journey
- 14:27
- Case Study
Konexa rolling out its integrated distribution model with multiple DISCOs across Nigeria. In its sub-concession area, Konexa will develop embedded generation capacity (solar PV), and invest in the distribution network (medium voltage line, distribution transformers, injection substations) and last mile reticulation (low voltage lines, smart metering infrastructure). In addition, Konexa will invest in and implement IT & OT systems and processes to drive operational efficiency and significantly reduce ATC&C losses. The first phase of the project would serve about 7,000 customers (C&I and residentials).
Remote Management of Protection Relays
- 23:45
- Case Study
This presentation defines and demonstrates the importance of remote data collection of protection relays for the security and reliability of large power system networks. Oman Electricity Transmission Company grid stations contain more than 5000 rapidly expanding protection relays installed. In case of tripping incidences, the protection system would isolate the faulty primary equipment by actuating the switchgear. These isolated equipment restorations can be done faster if protection relays’ fault records and events can be retrieved through remote access at any time. ETAP and OETC jointly worked to provide remote relay access and data retrieval. The protection system model and relay data feed in a relay management system solution, is called ETAP eProtect. This system is connected through IEC 61850 and IEC 60870-5-103 protocol to linked relays, events, and fault records. Fault records are stored in a database for detailed analysis and validation. This presentation discusses the challenges faced, technical requirements, and benefits of the solution.
