A model of the network that feeds the powerful controlled rectifier in the means of adjustment of starting modes is built. To solve the practical problem of determining the optimal location and placement scheme of automatic sectionalizing switchgear in distribution electrical networks, an adapted model for evaluating the optimal number and installation locations of sectional switching devices in distribution electrical networks is proposed. A study of voltage deviation and its fluctuations in distribution networks with a voltage of 110-220 kV, a study of voltage non-sinusoidality and asymmetry, dips and temporary voltage overshoots, as well as deviation of the frequency of the main voltage harmonic from nominal values using emergency situations registered by hardware and software means of information- of the "Regina" diagnostic complex. The obtained results were summarized and the quality indicators of electric energy were checked for compliance of their parameters with permissible and marginally permissible quality standards. A method of detection of single-phase earth faults in the distribution network based on the method of detection of seismic events STA/SLA is proposed. A technique for determining the trigger thresholds of the STA/SLA algorithm has been developed, which allows for a reliable determination of a single-phase ground fault. The actuation limits are defined in relative units, which allows the method to be adapted to changes in the network configuration. Product Description popup.authors Ivanochok Nataliya D.
