    Recently, the State Grid Corporation's first new online monitoring device for dynamic capacity increase of power ring was installed on the 220 kV Xiaxiao 2577 line in Nanjing, Jiangsu
    .

    It is understood that in recent years, with the increasing power load, the transmission capacity of some transmission lines is insufficient, especially during the peak summer period, the load will exceed the stability limit for a short time, and the cost of line reconstruction or replacement of double-capacity conductors is high and difficult to implement
    .
    Therefore, Nanjing Power Supply Company extensively investigated the current situation of technology at home and abroad, and decided to adopt a new online monitoring device
    for dynamic capacity increase of power ring.

    The power ring is installed on the transmission line wire, collects the wire current, the single relative ground voltage, phase angle, conductor temperature, inclination, 3D acceleration data and meteorological information of the conductor, and transmits the data to the background application system for processing after integration, and obtains the wire tension, wire sag and clearance, wire breeze vibration and dance, active, reactive, active, reactive and dynamic ampacity data
    .
    According to the real-time measurement data, the background application system provides three different dynamic ampacity
    under normal working conditions, accident states and emergency conditions after analysis and calculation.

    In the next stage, Nanjing Power Supply Company will gradually promote the use of this new online monitoring device on transmission lines to further improve the reliability
    of transmission line operation.
