COMPLEX FOR MONITORING DC CONTROL POWER SYSTEMS Russian patent published in 2018 - IPC G01R27/18 

FIELD: electrical engineering.

SUBSTANCE: field of application: electrical engineering. Complex for monitoring DC control power systems represents a set of functional units, complex includes: an indication unit for processing and displaying information, management of the complex as a whole and functional units separately, as well as for storing settings and logging events; information collection device for receiving control commands from the indication unit and transmitting them to the function units, receiving data from the function units and transferring it to the indication unit; battery monitoring unit with sensors for measuring and monitoring the battery current, asymmetry of battery voltages and current ripples, and also in conjunction with a temperature sensor for measuring and monitoring the temperature of the battery; voltage and current monitoring unit with sensors for measuring and monitoring voltage and current, as well as voltage and current ripples; discrete signals monitoring unit for evaluating the logic state of auxiliary contacts of circuit breakers, contactors, fuses; unit of test impact with an insulation monitoring unit for measuring and monitoring the total insulation resistance of the network and individual resistances, insulation resistance of the network at the poles, measuring and monitoring pole voltages relative to the ground, as well as test impact on the network in accordance with the algorithm for measuring insulation resistance, as well as optional-leveling resistors to create the required resistance of the poles relative to the ground, wherein the composition and number of functional units are determined by the set of mode parameters that need to be monitored and the DC control power system.

EFFECT: technical result is broader functional capabilities of the complex.
