An analysis of the reliability of the 22kV distribution network of the Nelson Mandela Bay Municipality

Lamour, Bernhardt Gustave January 2011 (has links)
This dissertation is a systematic study of the 22kV Nelson Mandela Bay Municipality (NMBM) electricity power distribution network reliability evaluation and improvements to be applied. Reliability evaluation of electric power systems has traditionally been an integral part of planning and operation. Changes in the electricity utility, coupled with aging electrical apparatus, create a need for more realistic techniques for power system reliability modelling. This work presents a reliability evaluation technique that combines set literature and evaluation criteria. In analysing system reliability, this research takes into account the reasons for many outages and voltage dips and seeks to find mitigating approaches that are financially justified. The study analyses the power system in terms of the methodology developed, using power system reliability techniques, power quality evaluation, protection analyses and evaluating the network against maintenance interventions and programs, manpower availability and weather conditions contributing to the outages. In evaluating the power system various techniques are used to determine if the power network operates within the NRS standards, namely, reliability calculations, testing of protection equipment, interrogation of power quality instruments and modeling the network on Digsilent. This study will look at all the important factors influencing power system reliability, analysing the network in terms of the methodology and recommend improvements.

Monitoring of power quality indices and assessment of signal distortions in wind farms

Novanda, Happy January 2012 (has links)
Power quality has become one of major concerns in the power industry. It can be described as the reliability of the electric power to maintain continuity operation of end-use equipment. Power quality problems are defined as deviation of voltage or current waveforms from the ideal value. The expansion plan of wind power generation has raised concern regarding how it influences the voltage and current signals. The variability nature of wind energy and the requirements of wind power generation increase the potential problems such as frequency and harmonic distortions. In order to analyze and mitigate problems in wind power generation, it is important to monitor power quality in wind farm. Therefore, the more accurate and reliable parameter estimation methods suitable for wind power generation are needed. Three parameter estimation methods are proposed in this thesis to estimate the unknown parameters, i.e. amplitude and phase angle of fundamental and harmonic components, DC component and system frequency, during the dynamic change in wind farm. In the first method, a self-tuning procedure is introduced to least square method to increase the immunity of the algorithm to noise. In the second method, nonrecursive Newton Type Algorithm is utilised to estimate the unknown parameters by obtaining the left pseudoinverse of Jacobian matrix. In the last technique, unscented transformation is used to replace the linearization procedure to obtain mean and covariance which will be used in Kalman filter method. All of the proposed methods have been tested rigorously using computer simulated data and have shown their capability to track the unknown parameters under extreme distortions. The performances of proposed methods have also been compared using real recorded data from several wind farms in Europe and have demonstrated high correlation. This comparison has verified that UKF requires the shortest processing time and STLS requires the longest.

Enterprise systems success: a measurement model

Sedera, Darshana January 2006 (has links)
Organizations make large investments in Information Systems (IS) expecting positive impacts to the organisation and its functions. Yet, there exists much controversy surrounding the 'potential' impacts of these systems, with some studies reporting broadly positive impacts of IS across organizations (Barua, Kriebel and Mukhopadhyay 1995; Barua and Lee 1997; Brynjolfsson and Hitt 1996; Lehr and Lichtenberg 1999; Mukherjee, Ray and Miller 2001), while others have shown nil or detrimental impacts (Attewell and Rule 1984; Brynjolfsson and Yang 1996; Cameron and Quinn 1988; Wilson 1993). Various authors have suggested that these conflicting results may be due to poor measurement - E.g. incomplete or inappropriate measures of success (DeLone and McLean 1992; Gable 1996; Melone 1990), lack of theoretical grounding and hence agreement on appropriate measures of success (Bonner 1995; Myers, Kappelman and Prybutok 1998), myopic focus on financial performance indicators (Ballantine, Bonner, Levy, Martin, Munro and Powell 1996; Kaplan and Norton 1996), weaknesses in survey instruments employed (Gable, Sedera and Chan 2003) (e.g., constructs lacking in validity), or (5) inappropriate data collection approach (Seddon, Staples, Patnayakuni and Bowtell 1999; Sedera and Gable 2004) (e.g., asking the wrong people, unrepresentative sample). Enterprise Systems (ES) have over the past decade emerged to be one of the most important developments in the corporate use of information technology. Anecdotal evidence reveals discontent with these large application software packages. Yet Enterprise System investments are seldom systematically evaluated post-implementation; the review process and measures typically being idiosyncratic and lacking credibility. Impacts resulting from 'Enterprise Systems' are particularly difficult to measure, with an Enterprise System entailing many users ranging from top executives to data entry operators; many applications that span the organization; and a diversity of capabilities and functionality. Despite the substantial investments made by organizations and the anecdotal evidence of discontent, systematic attempts to measure their success have been few. The primary objective of this research is to develop and test a standardized instrument for measuring ES-Success. Other related objectives of this research include: (1) to identify the dimensions and measures of ES-Success, (2) to validate a maximally generalizable measurement model and survey instrument for gauging ES-Success; (3) to develop an understanding of the state of Enterprise Systems using descriptive/comparative statistics, and (4) to identify and test an antecedent of ES-Success. With the above objectives, and in attention to the weaknesses identified in past IS-success research, this study follows and extends the 'research cycle' guidelines of Mackenzie and House (1979) and McGrath (1979). The research cycle entails two main phases: (1) an exploratory phase to develop the hypothesized measurement model, and (2) a confirmatory phase, to test the hypothesized measurement model against new data. The two surveys (termed as identification-survey and specification-survey) conducted in the exploratory phase of this research go beyond the activities recommended by Mackenzie and House (1979) and McGrath (1979). A third "confirmation-survey" was completed in the confirmatory phase of the research cycle. The three surveys gathered and analyzed data from six hundred (600) respondents. The purpose of the identification-survey was to discover the salient ES-Success dimensions and measures to include in an a-priori ES-Success model. Data from 137 respondents representing 27 Australian State Government Agencies that had implemented SAP R/3 in the late 1990s were analyzed. The analysis of identification-survey data yielded an a-priori model with 41 measures of 5 dimensions of ES-Success that provide a holistic view across the organization from strategic to operational levels. The specification-survey was employed to validate the a-priori ES-Success measurement model derived in the preceding identification-survey. Employing 310 responses from the same 27 public sector organizations, exploratory data analysis validated 27 measures of success pertaining to the 4 dimensions: information quality, system quality, individual impact and organizational impact. Data for testing the influence of an antecedent of ES-Success was simultaneously gathered during the specification-survey. This analysis, based on the Adaptive Structuration Theory (AST), investigated the influence of Knowledge Management Structures Adequacy (KMSA) on ES-Success. Preliminary results indicate a strong relationship between the Knowledge Management Structures Adequacy and ES-Success. The purpose of the confirmation-survey was to further validate the dimensions and measures of the ES-Success model, using new data, employing confirmatory statistical techniques. Data was gathered from 153 respondents across a large University that had implemented the Oracle Enterprise System, which facilitated further construct validity of the ES-Success measurement instrument was further established using Structural Equation Modeling (SEM).
