| Popis: | Methodical errors of simplified models of steady state of ultrahigh-voltage overhead lines have been investigated. It has been established that the error of these models does not correspond to the accuracy of PMU measurements. A method and algorithm for improving the accuracy of modeling by the mode parameters collected from PMU devices have been proposed. Chain model of an overhead line proposed in this paper takes actual weather conditions into account. Application of the proposed approach makes it possible to increase the accuracy of calculating steady state and state estimation and identifying the electrical parameters of the overhead line. This improves the effectiveness of transmission line control in real time. Proposed method was applied for existing 500-kV ultrahigh-voltage overhead line. |
