Bondarenko E. The theory of minimization of the risk in extra-high voltage electric installations

The dissertation is devoted to developing out the theory of an estimation of risk of the electrical accidents from action of electric energy in extra-high voltage electric installations. Proceeding from the analysis of a current state of a problem of the electrical safety in electric installations 330-750 кV, for strategy of the, electrical safety for extra-high voltage electric installations of pressure where the method of minimization of risk of the electrical accident is accepted. On the basis of theoretical researches of risk of the accident and occupational diseases it is established that for an estimation of risk of the electrical accident the cause and effect model is expedient. It is developed a structural and mathematical cause and effect model of risk of the electrical accident in electric installations 330-750 кV. The conditions of system of the electrical safety and possible transitions between them are analyzed. The methodology of an estimation of risk of the electrical accident in extra-high voltage, methods of a substantiation of maximum permissible parameters of the electrical safety and methods of the estimation of risk taking into account value of maximum permissible energy are developed. It has allowed to receive the unknown previously patterns for the procedure of the analysis of risk of the electrical accident and to prove technological indicators and actions directed on minimization of risk to health of the personnel from the action of electric energy of the industrial frequency.
