EVN and TNB Collaboration on Transmission Unmanned Substation

Twenty engineers from EVN National Power Transmission Corporation attended a 5 day training program Transmission Unmanned Substation from 17-21 April 2017 at Tenaga Nasional Berhad, Malaysia

Knowledge and skills in advanced technologies for managing transmission substation provides a competitive advantage and most likely to be of help to planners of transmission grids in responding to the challenges of the future. These issues have increased importance because of administrative complication and the fragmentation of public opinion expressed on the build-up of new infrastructure.

With phenomenal growth in the power to be transferred, it has become essential to transmit power with least interruptions and minimum losses with optimum number of transformations, to ensure least possible losses. These substations are the nerve centres of the transmission system by controlling and protecting the entire transmission network.

Of late, the regulators are also enforcing higher performance standards for transmission utilities to comply with. Penal provisions for non-compliance are in the offing. Efficient and economical design, erection and operation and maintenance procedures of substations without any compromise become paramount in providing reliable supply besides prolonging the life of equipment.

Meeting this changing scenario requires special skills on the part of the professionals of the transmission sector to handle the system efficiently and economically. This training programme is designed to provide a comprehensive knowledge and skills of planning, designing, operating and monitoring the system with advanced technology in mind.

The following topics were covered during the training: 

1. Overview of Transmission Grid Operation Philosophy
2. Control Centre SCADA/Energy Management System (EMS)
3. Transmission Substation Operation and Design
4. Advance Technology – Online Monitoring System
5. Advance Technology – Digital Substation & Substation Interrogation and Monitoring System
6. Advance Technology – Active Network Management and Grid Automation
7. Site visit to Conventional Transmission Substation or Network Control Centre (Depending on approval)
8. Site visit to Digital Transmission Substation
