Improvement of utilisation safety by a hierarchical method of analysis

Abstract

The safety of utilisation is one of the chief current preoccupations. The user must be able to know what impact the failure of one ore more network elements will have on the continuity of supply, as well as the countermeasures to be taken against degradation of the state of the system. It is therefore necessary to isolate critical instances of faults, to analyse their consequences taking into account the various local automatic mechanisms (adjustment and protection systems), and to search for methods to be implemented for maintaining the network in an assured state of use. A hierarchical approach is presented for solving this problem. Critical instances of faults are selected with the aid of an operations research algorithm specially adapted to the peculiarities of electrical networks. The consequences, both static and dynamic, are analysed by models of increasing complexity

Electrical network

An electrical network is an interconnection of electrical components (e.g., batteries, resistors, inductors, capacitors, switches, transistors) or a model of such an interconnection, consisting of electrical elements (e.g., voltage sources, current sources, resistances, inductances, capacitances). An electrical circuit is a network consisting of a closed loop, giving a return path for the current. Thus all circuits are networks, but not all networks are circuits (although networks without a closed loop are often imprecisely referred to as "circuits").

Hierarchy

A hierarchy (from Greek: ἱεραρχία, from hierarkhes, 'president of sacred rites') is an arrangement of items (objects, names, values, categories, etc.) that are represented as being "above", "below", or "at the same level as" one another. Hierarchy is an important concept in a wide variety of fields, such as architecture, philosophy, design, mathematics, computer science, organizational theory, systems theory, systematic biology, and the social sciences (especially political science).

Complexity

Complexity characterises the behaviour of a system or model whose components interact in multiple ways and follow local rules, leading to non-linearity, randomness, collective dynamics, hierarchy, and emergence. The term is generally used to characterize something with many parts where those parts interact with each other in multiple ways, culminating in a higher order of emergence greater than the sum of its parts. The study of these complex linkages at various scales is the main goal of complex systems theory.
