  • Development of Glass Fibre Reinforced Polymer Composite Crossarms for Transmission Line Structures

    EDM International - 2014 International Conference on Overhead Lines

    The paper describes the development, testing, engineering properties, design, advantages, manufacturing process and the field experiences with FRP crossarms for addressing new requirements for transmission lines asset management. Specifically, longer life cycle, lower operational costs and maintenance requirements, suitability for live line maintenance as well as aesthetics are addressed in addition to the generally required reliability improvements.

    A shared dedication to safety, transmission reliability, and the use of innovative technologies to improve business practices brought together Hydro-Québec and British Columbia Transmission Corporation (BCTC) in the field deployment and enhancement of a high-performance power line inspection robot. Since 2003, Hydro-Québec's research institute (IREQ) has been developing LineScout Technology (LST), a mobile robot capable of crossing many of the obstacles found on live transmission lines, which consists of a modular platform onto which various sensors and tools can be deployed. Consequently, BCTC Research and Development Department (BCTC R&D) engaged discussions with the IREQ team in 2006 and developed over the years a very fruitful collaboration in deploying and improving this technology. Field experiences in British Columbia with the LST demonstrate that it is ready for deployment in inspection practices on different transmission networks around the world. Furthermore, this paper shows how collaboration between utilities can leverage the assets of each partner and lessen several obstacles likely to be found in the path of introducing robotics for transmission line inspection and maintenance.

  • Smart View for a Smart Grid – Unmanned Aerial Vehicles for Transmission Lines

    2010 1st International Conference on Applied Robotics for the Power Industry (CARPI 2010)

    British Columbia Transmission Corporation (BCTC) operates high voltage transmission lines over mountainous terrain and remote locations, relying heavily on helicopters to maintain the system. This is inherently dangerous, expensive and has a negative impact on the company's Green House Gas emissions. Unmanned Aircraft Systems (UAS) are already a proven asset for military operations globally and with some modifications can be deployed along electric transmission lines as platforms for various…

    British Columbia Transmission Corporation (BCTC) operates high voltage transmission lines over mountainous terrain and remote locations, relying heavily on helicopters to maintain the system. This is inherently dangerous, expensive and has a negative impact on the company's Green House Gas emissions. Unmanned Aircraft Systems (UAS) are already a proven asset for military operations globally and with some modifications can be deployed along electric transmission lines as platforms for various sensors and multi-spectral camera systems. This paper reviews some of the possible applications of UAS in BCTC for routine and emergency line inspections and discusses the required system features based on internal research and needs assessments.

  • Wind and Ice Load Model Using Numerical Weather Prediction

    that can cause damage resulting in temporary loss of service. Because the reliability of power transmission networks is of crucial importance to society, the ability to predict potential

    This paper describes a forecasting model that can be used by utilities to estimate wind and ice storm impact on electric power grids. The grids are exposed to weather conditions
    that can cause damage resulting in temporary loss of service. Because the reliability of power transmission networks is of crucial importance to society, the ability to predict potential
    hazards and to plan possible mitigation measures in advance is of great interest. In this study, we concentrate on prediction of combined ice and wind loads, which cause most failures of overhead conductors and other components of power networks. Modeling of these loads requires estimation of forces exerted on the conductors due to wind and ice build up. The proposed system approaches this modeling problem in four stages. First,
    meteorological conditions in the area of interest are determined using a Numerical Weather Prediction (NWP) model. Second, NWP output is processed to obtain factors pertinent for wind and ice modeling: occurrence of freezing precipitation, precipitation rate, temperature, and wind velocity. These variables are derivedfrom NWP model output and corrected for the height of overhead
    conductors. The third stage involves an ice accretion model, which is engaged depending on the temperature and precipitation type. Fourth, a force model then calculates the force due to the
    weight of the ice, and the force of wind acting on the ice covered conductor. The resulting forces are then combined to determine the total load on the conductor. The system has been developed
    and verified using field data provided by the British Columbia Transmission Corporation (BCTC), Canada. The results indicate a good match between timing of peak forces determined by
    the system and observed outages.

  • Transmission Tower Seismic Risk Mitigation Strategy & Methodology for British Columbia Transmission Corporation

    ASCE TCLEE 7th International Conference on Lifeline Earthquake Engineering

    Transmission assets have typically performed well historically during earthquakes around the world. In the case of steel lattice towers in particular, the importance of these assets and the rigor of their design for climatic loadings provides added robustness against induced dynamic loading from earthquakes. Tower failures from ground motions during seismic events have largely been due to liquefaction, slope instability, lateral movements, and differential movements leading to localized tower…

    Transmission assets have typically performed well historically during earthquakes around the world. In the case of steel lattice towers in particular, the importance of these assets and the rigor of their design for climatic loadings provides added robustness against induced dynamic loading from earthquakes. Tower failures from ground motions during seismic events have largely been due to liquefaction, slope instability, lateral movements, and differential movements leading to localized tower footing failure. This paper demonstrates a utility’s approach for analysing seismic risks in order to prioritize, plan, fund and execute risk mitigation. Discussions on the analysis, design and evaluation carried out in order to make consistent decisions on the most cost effective engineering upgrade options are also included.

  • Response of Buried Power Transmission Cables to Earthquake-induced Permanent Ground Deformations

    The 14 th World Conference on Earthquake Engineering October 12-17, 2008, Beijing, China

    The performance of buried power transmission cables in areas subjected to ground deformations
    is an important engineering consideration for the utility owners. The performance of buried
    power transmission cables subjected to permanent relative axial ground displacements was
    investigated using a full-scale testing facility.
    The facility comprises a 2.5 m x 3.8 m soil chamber, with the capacity to subject buried transmission cables (or pipelines) to large relative…

    The performance of buried power transmission cables in areas subjected to ground deformations
    is an important engineering consideration for the utility owners. The performance of buried
    power transmission cables subjected to permanent relative axial ground displacements was
    investigated using a full-scale testing facility.
    The facility comprises a 2.5 m x 3.8 m soil chamber, with the capacity to subject buried transmission cables (or pipelines) to large relative displacements.
    The buried cables were subjected to relative axial and transverse soil movements, and the test
    results are compared with the response predicted from commonly used approaches to assess the
    performance of buried pipelines. The peak loads under relative axial soil movements on cables
    buried in dense soil were noted to be under-predicted by the current approaches; this is likely due
    to the increased soil normal stresses on the cable due to constrained soil dilation not accounted by
    the current approaches. The general trend of the predicted response using current approaches for
    pipelines under lateral loading is in reasonable agreement with the experimental observations,
    although direct comparisons between the test results and the predictions were difficult due to the
    three-dimensional cable deformation patterns arising from lateral loading tests.
