A problem of power supply of microprocessor-based protective relays at emergency mode
The paper discusses a problem of power supply for microprocessor-based protective relays in a substation with AC and DC auxiliary voltage in an emergency mode. The paper recommends application of power capacitors and supercapacitors instead of UPS as energy storage elements for shorttime duration fe...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | The paper discusses a problem of power supply for microprocessor-based protective relays in a substation with AC and DC auxiliary voltage in an emergency mode. The paper recommends application of power capacitors and supercapacitors instead of UPS as energy storage elements for shorttime duration feeding of protective relays in emergency modes. |
