TrafoGrade system - Opis:
-
W artykule przedstawiono metodykę i przykładowe wyniki diagnostyki transformatorów elektroenergetycznych prowadzonej z wykorzystaniem systemu TrafoGrade, który opracowano i wdrożono w firmie Energo - Complex. Scharakteryzowano poszczególne części składowe systemu takie jak ocena stanu technicznego, ocena znaczenia transformatora w systemie elektroenergetycznym oraz analiza ekonomicznych perspektyw eksploatacji. Przedstawiono również koncepcję stworzenia systemu komputerowego do zarządzania populacją transformatorów. Podano przykładowe analizy wykonane w oparciu o otrzymane wyniki pomiarowe z 45 transformatorów rozdzielczych zainstalowanych w jednej ze spółek dystrybucyjnych działających na terenie Polski.
Power transformers are significant part of assets owned by entities distributing and transferring electric energy. In Poland, there are several thousands of medium and high power transformers operated, while over 50% of them is older than 30 years, what means they have already exceeded their planned lifetime. At present in Europe there are not sufficient production and financial means allowing to exchange most of transformers population in the close future. The only possibility is maximally to prolong the operation of already installed old units [1]. To help fulfilling this task Energo-Complex Ltd. has elaborated complex system of transformers management, named TrafoGrade, which is based on the point scale assessment of transformer's technical condition, its importance in the power grid and linking technical aspects of diagnostics with economic-financial factors to conduct decision process optimizing in the range of routine exploitation, repairs planning and investment policy [2]. The assessment of technical ondition with TrafoGrade system is based on analysis of 15 parameters obtained from diagnostic measurements, divided into three groups (Fig. 2). The paper presents examples of technical condition assessment (Fig. 4, 5, 6) and describes operational possibilities for 45 distribution transformers installed in one of distribution companies operating in Poland. For the operation planning and rationalization, the technical condition of transformers was linked to their importance in power system (Fig. 7), which allowed to divide given population into three basic groups of further exploitation: transformers with simplified operation (U), transformers with normal operation (N) and transformers with special operation (S). TrafoGrade system is a modern tool for diagnostics and management of transformers. The complex assessment of technical condition gives a lot of important information to be applied in logistic actions and financial policy of transformers operators. The important advantage of TrafoGrade system is simple form of assessment presentation, helping to analyze results of measurement both by engineering staff and managing personnel without wide technical knowledge. - Źródło:
