Numerical Simulation on the Aerodynamic Force of the Iced Conductor for Different Angles of Attack
Article history: Received: 19.06.2014. Received in revised form: 06.11.2014. Accepted: 11.11.2014. According to the galloping mechanism of iced conductors, the aerodynamic simulations were performed based on actual wind tunnel tests. Aeroelastic models of single and bundled conductors with a typical ice-coating section forms (crescent section) were set up. The simulation results were in good ag...
متن کاملTransmission Line Conductor Galloping Analysis using FEM
To find a mathematical standard of the galloping mechanism, and it is required to compare the existing mathematical standards on the conductor galloping. In this paper, using the Hamilton principle the continuum cable standard for transmission lines was proposed. Discrete standards of one degree of freedom, two degree of freedom, and three degree of freedom were obtained from the Garlekin funct...
متن کاملThe Aerodynamic Analysis for Iced Four Bundled Transmission Lines with Typical Crescent
Despite the fact that the wind tunnel tests have been carried out on iced transmission lines subjected to wind load, it is not practical to do wind tunnel tests due to its high cost. This paper describes a detailed numerical simulation method that can be used to instead of wind tunnel tests. Based on the galloping mechanism of iced transmission lines, the aerodynamic test was simulated with the...
متن کاملNumerical Investigation of Galloping Instabilities in Z-Shaped Profiles
Aeroelastic effects are relatively common in the design of modern civil constructions such as office blocks, airport terminal buildings, and factories. Typical flexible structures exposed to the action of wind are shading devices, normally slats or louvers. A typical cross-section for such elements is a Z-shaped profile, made out of a central web and two-side wings. Galloping instabilities are ...
متن کاملDesign of a Wireless Sensor Module for Monitoring Conductor Galloping of Transmission Lines
Conductor galloping may cause flashovers and even tower collapses. The available conductor galloping monitoring methods often employ acceleration sensors to measure the conductor translations without considering the conductor twist. In this paper, a new sensor for monitoring conductor galloping of transmission lines based on an inertial measurement unit and wireless communication is proposed. A...
