METHOD AND SYSTEM FOR REMOTE MEASUREMENT OF AVAILABLE CAPACITY OF THE BATTERIES IN THE TELECOMMUNICATIONS POWER SYSTEM

摘要

Proposed method and system provide remote measurement of available capacity of the batteries, which are the reserve of energy in the telecommunications facilities, mainly those comprised in the critical telecommunications infrastructure. To initiate remotely individual discharge of each of at least two batteries in the power system (PS), the system negative bus (-) is connected to the battery (B1, Bn) through the individual high-current contactors (P1, Pn), replacing the common low-voltage switch, which are connected by the microprocessor control unit (MCU), which also controls the low-current contactors (p1, pN) connected to these batteries, and with the second contacts connected to the second input (B) of the controlling-measuring device (TBA-ST). This device is permanently installed in the power system (PS) and at the command from the monitoring center (MC) it measures using the method of controlled discharge with constant current, the capacity of each of the batteries, disconnected by the microprocessor control unit from the power system during this operation.
