A new technique for active minimal cut set selection used in substation reliability evaluation

In this paper is presented a substations reliability analysis based upon substation’s component outage or failure modes. The switching actions can be modelled in the reliability evaluation indices we used the three-state model of the substation components (for example circuit breaker). The reliability indices are evaluated using the minimal cut-set method for each components of substation.

Smart Substation

As an important part of smart grid, smart substation is the acquisition source of operating data and command execution unit, and also acts as the important foundation and support of smart grid. With the continuous deepening of smart substation construction in State Grid Corporation, the overall integration design concept of the new generation smart substation based on research and development of new equipment has been put forward, realizing the main electrical connection optimization and improvement of reliability .Concerning the characteristic and application of DCB in smart substation, reliability of three kinds of typical main electrical connection schemes in existing substation and smart substation is calculated by the minimal cut-set method in this paper.

Underwater Structures

Abstract The decommissioning of underwater structures has expanded in recent years, as the number of facilities at the end of their useful lives is increasing and legislation becomes more severe. Unlike the production units which already have their decommissioning plans consolidated, subsea pipelines represent the greatest technological, environmental and financial challenge of this stage. Currently, there are few studies to evaluate failures in the decommissioning of flexible pipelines. In addition, these studies generally use simplified analyses. Therefore, this study aims to elaborate a failure analysis for a Reverse Reeling option, in order to contribute to the decision-making process and reduction of failures. For this, a Fault Tree Analysis will be developed followed by the subsequent elaboration of its minimum cut sets. The main results present a total of 13 first-order minimal cut set, 5 second-order minimal cut set and 7 third-order minimal cut set.
