Question 1 You are a consulting engineer working in Power Systems Protection. You are required to analyse and assess the protection system for two Eskom power Stations located next to each other in Kriel, Mpumalnga Province, as well as the protection system on a potential distribution network the company plans to build. 1. Name and give a brief overview of these two Power Stations. Also highlight the similarities and differences including ratings, technology, applicable protection at power stations such as these, etc. (20) 2. Evaluate available power system simulation software programs and list them (Maximum of 5) that can calculate fault levels and choose a software program to use to evaluate analyse the network in 2. Briefly describe the features of three software programs, including history, owner, how it works, positives and negatives. Describe the rationale in choosing the software for use in this assessment. (15) 3. Design a network layout and give the network diagram for a potential distribution network Eskom wants to build to be connected to both Power Stations. This network should be drawn in the software chosen in The network should include and show all transformers and protection equipment (You do not need to get the exact equipment that is at these power stations for protection equipment). The network should have 16 substations that are at 22 kV and 11kV being supplied from the power station. These should respectively be in a 50% split. The network should include a ring network with two 22 kV substations. Two of the 11kv substations should be supplied, respectively, from two 22 kV substations (One 22 kV in the ring supplied from the first power station and another not in a ring supplied from the second power station). The substations should be n-1 firm with transformers and supply feeders. The power station should have in feeds into the common 22kV network. (40) APT4801 Assessment 4. Calculate the fault levels at each substation’s secondary bus-bar using the software chosen in 3 and give the results as well as the fault level at the generator transformers’ secondary and primary side. Record the simulation and Discuss the observations/Results. (25)
