CASE STUDIES ON PROJECTS

These case studies tell the stories of technological projects from conception to completion.

 

Case Study: Automobile Association of SA (AASA) implementation of a fully integrated workforce management solution

AASA faced several challenges with their bespoke workforce management solution. They realised the need for a fully integrated platform that can expand into an optimised and automated workforce management system. The business experienced challenges with communication between the current dispatch system and the mobile application, leading to great frustration between dispatchers and technicians. In addition to this, there was limited visibility into the activities of the resources.

This made it difficult to determine whether they were able to stay on schedule and meet the day’s obligations. Many procedures were handled manually because of communication problems. The scattered systems often forced employees to enter information multiple times, leading to discrepancies and incorrect data.

Case Study: De Aar Wind Farm Facility Protection, Control, Automation and DC Solution

Adenco Construction was awarded the electrical construction for two wind farms in De Aar, Northern Cape South Africa by Longyuan South Africa Renewables.

De Aar 1 is a 100MW, 67 WTG wind farm. De Aar 2 is a 140MW, 96 tower wind farm. Longyuan will invest a total of R 5 billion into the two projects. The construction start date was 11 January 2016.

Adenco had the construction abilities but did not have the capabilities or the experience to tackle the electrical substation Protection, Control, Automation, DC system supply, testing and commissioning.

Case Study: Duvha – EMDAS

Each power station has its own individual needs as there may be legacy equipment and systems already in place. It may not be in the plant’s best interest to replace all legacy devices and several aspects should be reviewed for the change-over process and requirements between systems. Topics for consideration include:

  • New EMDAS Eskom Standard
  • Metering best practices
  • Bus communication architecture
  • Equipment life expectancy
  • Effective use of available equipment and infrastructure
  • Outage schedules for installation of new equipment
  • IT/OT Interfacing
  • System Ownership within Eskom

Case Study: ESKOM – Capacitor Bank Protection

ESKOM had a requirement to have a National Transmission Contract for capacitor bank protection schemes that will be able to protect, monitor and control their capacitor banks for voltages ranging from 88 kV to 400 kV and for capacitor banks ranging from reactive power of 36MVAr to 150MVAr.

Eskom is a National South African electricity public utility, established in 1923.

The utility is the largest producer of electricity in Africa is among the top seven utilities in the world in terms of generation capacity and among the top nine in terms of sales.

The company is divided into Generation, Transmission and Distribution divisions and together Eskom generates approximately 95% of electricity used in South Africa.
