  • Study on Seismic Reliability of UHVDC Transmission Systems

    An assessment model of system seismic reliability was proposed based on the state enumeration method. A case study was presented by taking a typical 800 kV UHVDC transmission system as the example. The finite element models of major components in the UHVDC transmission system were established to evaluate their seismic reliability.Cited by: 1

    Detection risk forms the residual risk after taking into consideration the inherent and control risks pertaining to the audit engagement and the overall audit risk that the auditor is willing to accept. Where the auditor’s assessment of inherent and control risk is high, the detection risk is set at a lower level to keep the audit risk at an acceptable level.

  • Protecting Distance between Radar Stations and UHV Power

    Abstract. With the construction of UHV (Ultra-High Voltage) transmission lines and radar stations, the interference of UHV transmission lines to air intelligence radar stations has become increasingly prominent. Aiming at the problem that it is difficult to solve the loss of radar detection range caused by UHV transmission lines, the idea of using RCS (Radar Cross Section) of UHV transmission towers as an intermediate parameter to solve the radar detection
