- Description: The South African Automotive industry has been one that has enjoyed the subsidies schemes like the Motor Industry Development Program (MIDP), and in the near future the Automotive Production Development Program (APDP). There are however different schools of thought when it comes to subsidies for an industry. One is that there should be no incentives when others are for the schemes, which one is best for the growing economy of a young democratic and highly unemployed nation? Looking at the next planned incentive scheme to be introduced to replace the MIDP, the APDP is it better than the MIDP? How are these schemes going to benefit the country in the future and will they exist for as long as we have the Auto industry in South Africa? The objective is to prompt those in political power and positions capable of influencing infrastructure changes to think long term when making decisions today that will affect future generations. Future generations should be able to benefit from future technologies of the day and not be hindered by the lack of improved and capable infrastructure.

- Description: The research work conducted and presented forward in this document is the evaluation of real time values obtained using three recording devices at two independent locations and implementing them as recorder devices in Eskom’s power system. The research work conducted was presented at an IEEE International Conference (ICIT2013) and Appendix A shows the accepted paper presented. A derived model within a simulation software package known as DIgSILENT PowerFactory is created and Electromagnetic Transient (EMT) studies are performed and then compared to the real time values obtained using the OMICRON CMC 356’s. Transformers are normally energised via a circuit breaker which is controlled by an auxiliary closing contact. By applying system voltage at a random instant in time on the transformer windings may result in a large transient magnetizing inrush current which causes high orders of 2nd harmonic currents to flow under no load conditions. A philosophy known to mitigate these currents is to energise the transformer by controlling each individual phase 120 degrees apart with the first pole closing at the peak on the voltage waveform. Transients produced due to 500MVA transformers been introduced into the power system at a certain space in time can cause nuisance tripping’s at the particular location where the respective transformer is energised. OMICRON EnerLyzer is the software tool used for the Comtrade recordings at both locations. Four independent case studies are generated within EnerLyzer software and the relevant Comtrade files are extracted for the four independent case studies relative to Transformer1 and Transformer2 switching’s. TOP software, which is a mathematical tool used to analyse Comtrade files, is then used to analyse and investigate the four case studies. Results from DIgSILENT PowerFactory are then generated according to the derived model. The results extracted depict three scenarios, indicating a power system that is weak, strong and specifically a power system that correlates to the actual tripping of a Static VAr Compensator (SVC). The results are all formulated and then evaluated in order to produce a conclusion and bring forward recommendations to Eskom in order to effectively ensure the Dedisa/Grassridge power system is reliable once again.
