MANAGEMENT OF LOW-VOLTAGE NETWORK CLUSTER MODES
The results of computer simulation of normal and emergency modes low-voltage network cluster constructed on the basis of a direct current insert are presented. With this structure, it is possible to obtain the following positive effects: increased reliability of power supply; improve power quality; reduction of voltage dips; limiting short circuit currents; creating simple interfaces for the connection of batteries, led light sources, static frequency converters without rectifiers, etc.; improving the operating conditions of distributed generation plants. The results of computer modeling made it possible to draw the following conclusions: - the presence of direct current bus allows you to connect non-traditional sources of electricity; these sources make it possible to increase the reliability of electricity supply to non-traction consumers of AC railroads; - the insertion of a direct current provides an appreciable limitation of short-circuit currents; - there is a principal possibility of reducing the duration of voltage dips of shallow depth based on the regulation of the modulation factor of the inverter.
