In this study, the influence of climatic factors on overhead transmission lines reliability in Russia was discussed. A review of the possible impacts of climate change is provided. Using the example of an electric grid company providing electricity in the Republic of Bashkortostan some reliability targets associated with the impacts of weather events were calculated: the number of power outages, the failure rate of 1 km of overhead transmission lines and the outage time. From the calculations it was determined that these targets are at a quite high level, in particular for 6-10 kV overhead transmission lines. The main contribution is made by climatic factors wind and lighting storm. A correlation analysis of the overhead transmission lines outages as a function of the number of wind cases with a certain speed has shown a strong relationship between these characteristics. According to predictive information, the number of power outages in the territory under consideration in 2025 will increase by 1.5 times.
The task of improving the accounting system and accidents analysis at the industrial enterprises for many years has not lost its relevance, both in Russia and abroad. The root causes identification of injuries is an important stage for the development and implementation of preventive and adaptive measures to reduce the risk of injury rate of the employees. The article reflects the results of analysis for the main causes of industrial injuries, which shows the relationship between the traditional classification of injuries causes and the classification used at the state level when reporting by the authorized federal agencies. It is established that currently in Russia, when analyzing injury rate, the fairly wide range of possible causes is not considered, primarily related to the «human factor». The comparative assessment is given concerning the deterministic and probabilistic-statistical methods for analyzing industrial injuries, their main advantages and disadvantages are shown. It is established that the deterministic methods of analysis are characterized by a high level of analytical assessment of causes and factors, but the high time and labor costs of the experts involved become a serious difficulty in implementing this method. Probabilistic-statistical methods are more advanced, the methods are used to model predictive values of injuries based on the current information about the occurred incidents. Also analyzed are the characteristics of industrial injuries indicators, which are result-oriented (post factum) — lagging behind, and process —oriented (forecast) — leading. Lagging indicators are a retrospective description of the labor protection state at a production facility, while leading indicators characterize actions already performed and predict the result of the activities efficiency. The expediency of using leading indicators to make a predictive assessment of the industrial safety state and, consequently, to develop a systematic approach to minimize the number of incidents is justified.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
