The influence of outsourcing the core deliverables on the business performance at Eskom Distribution South AfricaMagagula, Marcia January 2017 (has links)
Submitted in fulfilment of the requirements for Degree of Master of Management Sciences: Business Administration, Durban University of Technology, 2017. / The execution of maintenance and repairs are the core business deliverables of the Power Plant Maintenance (PPM) department at Eskom Distribution South Africa (SA). However, external service providers are employed to similarly execute these deliverables. Given this background, this study aimed to determine the influence of outsourcing core deliverables on the performance of the PPM department at Eskom SA. This quantitative study sought to determine the prevalence of any statistically significant differences in the degree of respondents’ responses regarding outsourcing the core business deliverables of their respective PPM departments in terms of profile factors such as gender, marital status, age, education qualification, designation and length of service. The study was carried out in eight out of nine PPM departments. A total of 135 responses were attained from a possible 152 participants, providing a response rate of 89 percent. The study was successful in the achievement of all the objectives. The results of the chi-square and regression tests revealed the presence of significant factors contributing to the outsourcing of core business deliverables, accomplishing the first objective. The results of the chi-square and correlation tests revealed that outsourcing did effect business performance, though this was not generally an enhancing effect, accomplishing the second objective. Results of the chi-square tests also highlighted significant effects on the motivation of internal employees when the repairs and maintenance of the power plant equipment are outsourced, accomplishing the third objective. The results of the correlation and chi-square also highlighted the effect of managing the core business deliverables on the business performance, the motivation of internal employees, as well as the alleviation of significant risks resulting from outsourcing core deliverables. The coefficient of determination (R-squared) revealed only 33 percent of the variations in the dependent variable that were explained by the independent variables. Finally, there was an indication of statistically acceptable reliability for the variables of the study. / M

In this dissertation, the problem of multi-area load frequency control in large power systems is investigated. The load frequency control problem is concerned with the minimization of the deviations in the frequencies of the different areas and in the tie line power exchange between these areas, and is a problem of major importance in the satisfactory operation of large power systems. Some new techniques for designing load frequency control systems are presented through the use of concepts from singular perturbation and hierarchical system theory. To provide appropriate vehicles for the design of the new control systems, state variable models for power systems are developed. These models progress from a two-area interconnected power system model to large scale models comprising of N areas. Two centralized state feedback schemes are proposed for the load frequency control by utilizing the separation of the system models into two time scales. In the first scheme, composite controls and reduced order controls are developed to meet the required performance specifications by. The second scheme is obtained by using the theory of variable structure systems where the existence of a sliding regime leads to the design of a single discontinuous state feedback controller that meets the performance requirements. In order to further improve the performance of the closed loop system, a two level hierarchical control scheme is developed. This consists of a set of local controllers that are designed using either the singular perturbation approach or the variable structure system approach as before and a set of global control functions provided by a higher level controller that attempts to coordinate the local controllers. The interaction prediction principle is used as a tool in the design of the global controller. The performance of the presently developed control schemes is examined in detail for the illustrative cases of a two-area and a three-area power system. From this analysis, it is shown that these controllers provide an improved performance compared to the existing control schemes in reducing the frequency and tie line power deviations.
