This article introduces a new method of permanent inspection of technical active power losses. It is based on analytical computer code calculation with examples from the actual power system. Based on the incoming data from the remote control supervising system as well as technical and commercial information data, the result of the calculation is technical losses for every single element of the network. Further calculation result analysis enables global understanding of commercial losses as well as more quality planning and operating of the distribution network.
The main idea of this paper is presentation of the useful tool for detection of electric energy stealing on main power cable. Transmission line theory and Time Domain Reflectometer (TDR) was starting point for developing described application for determining of exact length location of illegal connection. Several examples, presented here, show our experiences in method applying.
Losses of electrical energy in the Croatian distribution network are frequently the subject of various discussions, from the professional and business aspects as well as in the media, and their analysis is an intricate matter complicated by the problem of the distinction between technical and nontechnical losses. In the article, the main factors and their impact on the amount of loss are described, with particular attention to trends in the past and current decade and comparison to losses in other European countries. Moreover, the chief activities for reducing these losses effectively are described. With the new legislative framework, the reduction of losses becomes a central concern for both the distribution system operator and the Croatian Energy Regulatory Agency (CERA).
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.
