Reliability and Safety of Mine Hoist Installations

Safety and inspection planning of older installations

A basic assumption often made in risk/reliability based inspection planning is that a Bayesian approach can be used. This implies that probabilities of failure can be updated in a consistent way when new information (from inspections and repairs) becomes available. The Bayesian approach and a no-crack detection assumption implies that the inspection time intervals usually become longer and long...

Safety culture in nuclear installations

FOREWORD This guidance has been developed for use in the IAEA's Safety Culture Services, which provides support to Member States in their efforts to develop a sound safety culture of their organizations. It will be of particular use in seminars and training workshops that are part of these services. Much of the information in this publication reflects the approach the IAEA has adopted to assist...

Modeling and Analysis of Harmonic in the Mine Hoist Cnverter Based on Double Closed-Loop Control

In the process of converter driving mine hoist, the output voltage waveform of the inverter is distorted. A novel feedback control method based on the filter inductor current inside loop and voltage is developed in this study. The transfer function model of the two closed-loop control is builded. Parameters of the PID controller are determined through theoretical calculation after analysis of t...
