Remote Monitoring Technology of the Performances of the Battery Charger in Digitalized Transformer Substation
DC power system is necessary to various power plants, transformer substations and power stations. Its main function is backup for the main power supply. When the main power supply interrupts suddenly, The DC power system can afford electrical source to the main control devices, faults monitoring system, faults protection system, etc. In the DC power system of the unwatched transformer substation, the battery charger is one of the key devices. The stability of its performances directly affect the stability of DC power system. In the paper, using the computer technologies and the realtime Ethernet technology to communicate with the batten charger monitor to achieve remote monitoring technology of the performances of the battery charger. It can not only remote monitor the operations and fault states of the battery charger on line, but also remote sensing the ripple factor and the stabilized voltage precision when the battery charger is under the states of the floating charge and the constant voltage equalizing charge, at the same time remote sensing the stabilized current precisions when the battery charger is under the stage of constant current equalizing charge, and the characteristics of equalizing current when the battery charger is in operation. So the remote monitoring technology of the performances of the battery charger is very important in the transformer substation.
