New formulation of the loadflow problemJalaliKushki, Hossein January 1973 (has links)
The new formulation of the loadflow problem presented in this thesis yields a set of equations each of which has only one nonlinear term. The equations are derived from the corrections required to make the final values equal to the initial estimated values. The resultant set of equations can be used when the initial estimated values are adjusted to their final values. However, derivation of the equations for this latter case results in a set of equations with (n1) nonlinear terms in each equation for an nbus power system. Five algorithms based upon the new formulation are described. Numerical tests on several sample power systems show that some of the new algorithms possess better convergence and speed characteristics than the commonly used WardHale and Newton algorithms. / Applied Science, Faculty of / Electrical and Computer Engineering, Department of / Graduate

The effect of local motor loads on power system stability.Prior, Bruce George January 1971 (has links)
The effect of local motor loads on power system stability is investigated. The power system consists of a synchronous generator supplying a large system through a long transmission line. The loads studied are an induction motor, a synchronous motor, and the combination of the two, although a general case of any number of local induction and synchronous motor leads can be easily formulated. Stability is determined by observing the response of the generator and the motors of the system with a fault at the transmission line. The response is calculated from the mathematical model and is also observed from tests on a dynamic power system model in the laboratory. It is found from the studies that all the local motor loads improve the stability of a power system. / Applied Science, Faculty of / Electrical and Computer Engineering, Department of / Graduate

Linear optical stabilization and representation of multimachine power systemsMoussa, Hamdy Aly Mohammed January 1971 (has links)
Linear optimal regulators have been designed for power system stabilization by introducing control signals to voltage regulators and/or governors. A new technique is developed in this thesis to determine the state weighting matrix Q of the regulator performance function with a dominant eigenvalue shift of the closed loop optimal system. The technique is used to investigate the stabilization of a typical onemachine infinite system and a multimachine system with different stabilization schemes. The objective is to find the best way to stabilize a power system. An optimally sensitive controller is also developed to offset the effects of the changing system operating conditions on the effort of the stabilizing signal. The controller automatically adjusts its gains so that it always provides the system with the optimum stabilizing signal. A new multimachine state variable formulation, necessary for these studies, is developed. It requires minimum computations and retains all the parameter information for sensitivity studies. An exact representation of synchronous machines is investigated and test methods are suggested for the determination of exact circuit parameters. / Applied Science, Faculty of / Electrical and Computer Engineering, Department of / Graduate

Simulation decision aid for power station configuration evaluationElliott, Kevin A. 02 March 2015 (has links)
M.Tech. / In life extending and refurbishing old power station plant, the following question must be addressed: Does one maintain current configuration, which was based on the technology of 1960, or make use of current power utility technology trends, and change the power station's configuration. This specific problem involves four existing Eskom power stations, with an approximate combined replacement value of R7 billion. All these stations have the capability of using a common steam feed range to supply superheated steam to the turbogenerator sets. This common steam feed range becomes very maintenance intensive in its "old age". Hence the need for this study into the feasibility of its refurbishment. This common steam feed range configuration was considered stateoftheart in the mid1900's, but is currently not the practised technology. This is primarily due to the technology advancement into reheat boilers, making control of a range type configuration impossible. Monte Carlo simulation provides an effective, holistic decision mechanism, that is free from bias, emotions and conjecture. Hence the simulation product, highlighted in this dissertation, will have solved an industrial problem finally and effectively, by ensuring that for a relatively small cost of building the simulation models, major capital expenditure estimates can be accurate, with a confidence in the return on investment. This paper discusses the use of Monte Carlo simulation modelling as an engineering analysis tool, for the analysis of two power station configuration options, i.e. with a steam feed range and without. Firstly, an investigation into the selection of which computer language to use as a development tool is presented. The Monte Carlo simulation technique is then explained, and simulation models are built of the two power station configurations. The models, which are built using SIMSCRIPT 11.5 simulation language to represent the real world in each configuration option, are then discussed. The availability analysis is developed, and conclusions and recommendations are discussed, as presented in the report to Eskom Management.
