Stand-alone power supplies for relay protection
At present, telemetry and relay protection devices, which are located directly on the protected element of the electric power system or inside it, are increasingly used in the electric power industry. To supply them requires an autonomous source of low power, which has a stabilized DC voltage. Ex...

| Summary: | At present, telemetry and relay protection devices, which are
located directly on the protected element of the electric power
system or inside it, are increasingly used in the electric power industry. To supply them requires an autonomous source of low
power, which has a stabilized DC voltage. Existing devices are
unreliable, expensive to manufacture and operate. In contrast
to the well-known power supply devices, it is proposed to use
Autonomous power sources to provide constant current for relay
protection and diagnostics devices, which receive energy directly
from the network by means of current or voltage transformers, as
well as by means of an induction Converter located in the end
zone of the electric machine. To implement this, the schemes of
power supply and calculation of the parameters of Autonomous
power sources have been designed. |
