| dc.description.abstract | Failures originating within a generating station can create significant system disturbances. It is essential to carefully design the station arrangement in order that faults originating in the station have minimum effect on the overall power network. Reliability assessment of an individual generating station can highlight the effect of a particular configuration and thus provide detailed and comparative information for decision making when planning that station. This thesis is concerned with individual generating station adequacy and security assessment. New indices, models and techniques have been developed in this research work, which recognize the application and purpose behind the assessment of an individual generating station. A series of indices are proposed. These include adequacy parameters, indices implicitly indicating operating security and indices that can be used to express the effect of station originated outages on the related power network. The possible weaknesses of the conventional three state model are investigated. The results show that the existing dependencies and practical restorative actions cannot be completely represented using this model. In order to overcome these weaknesses, system originated state transition models for several types of failure events were established and a generalized n+2 state system Markov model formed. The numerical comparisons show that the difference between the results calculated using the generalized n+2 state model and the three state model are significant for some cases. A systematic technique and a prototype computer program for large individual generating station reliability assessment were developed based on the index structure and the generalized n+2 state system model. Factors such as stuck breaker conditions, normally open components and the optimal switching sequence are incorporated in the algorithm and computer program. The Three Gorge power station in China, which will be the largest hydro generating station in the world, is used as a particular engineering example to illustrate and investigate the possible applications of the proposed techniques in practical engineering planning. Nine alternative switchgear arrangements have been assessed. An adequacy assessment, a security assessment and an overall comparison are presented. An optimum design based on the available date is given. The reliability engineering assessment of the Three Gorge project described in this thesis indicates that the developed indices, models and quantitative techniques can be applied in practical engineering situations to provide valuable information for planning decisions. | |
