ABB, the leading power and automation technology group, is supplying a R1,2 M UniPack Compact Substation to the chemical engineering building of the Cape Peninsula University of Technology (CPUT). The compact substation will help to improve monitoring of its electrical network and will offer a real-time training platform for critical electrical engineering skills.
The order was booked in May 2016 and delivery is expected in November 2016. The new UniPack Compact Substation, the first supplied by ABB in South Africa, is a special type of mini substation that facilitates viewing and analysis of electrical signals fed to a control room computer screen known as a Remote Terminal Unit (RTU). Installation of the new substation is part of the current CPUT project for refurbishment of the Bellville campus electrical reticulation network with new switchgear and new protective relays compatible with the IEC 61850 standard technology. This project was initiated to implement the research outcomes achieved by the postgraduate students at the Centre for Substation Automation and Energy Management Systems.
An important consideration for the customer in the implementation of ABB’s UniPack compact substation was compliance with IEC 61850 and compatibility for intelligent electronic devices (IEDs). ABB’s substation automation products and systems are fully compliant with the IEC 61850 standard. This open protocol covers all communication issues inside the substation, assures interoperability between the functions existing inside the substation, supports all types of architectures used, reduces operating costs and safe-guards investments. ABB has delivered numerous IEC 61850 based substation automation systems worldwide.
"The compact substation, with its automation system, will assist the university to monitor its electrical network status, equipment such as closed circuit breakers, open circuit breakers as well as protection trip history and electrical fault location," says Manie Jooste, Product Group Manager, Secondary Switchgear and Modular Systems, Electrification Products. "Another major benefit for the university is that the Electrical Engineering students, can now observe real-time substation statuses and conditions to assist in their training and applying of theory to practice,” says Jooste.
ABB's scope of supply of electrical equipment for the compact substation includes medium voltage switchgear (Ring Main Unit SafeRing 12 kV) together with a SCADA (Supervisory Control and Data Acquisition) interface, fuse-switch disconnectors, low-voltage switchboard, 1 MVA distribution transformer including cables and cable accessories. "This system is also beneficial for municipalities where they can monitor their compact substations that could be located in remote areas," says Jooste. "One central control room allows an overview of the full electrical system.”
Jooste explains that municipal electrical utilities will be able to dispatch technicians directly to a substation where an electrical fault has occurred. "It is more efficient than driving along the distribution network to try and determine the location of the fault," says Jooste. “In remote areas it is safer for personnel and reduces down time to the end users. Through this system you have the full visibility and status of the electrical network at your fingertips."
