This offers the following advantages: The time does not drift off from the reference time. A continuously accumulating deviation from the reference time thereby will be balanced.

    Time Synchronisation SNTP SNTP Important pre-condition: The protective relay needs to have access to a SNTP server via the connected network. This server preferably should be installed locally. Principle – General Use SNTP is a standard protocol for time synchronisation via a network. For this at least one SNTP server has to be available within the network.
  • Page 223 Time Synchronisation Accuracy The accuracy of the used SNTP server and the excellence of its reference clock influences the accuracy of the protection relay's clock. For further information about accuracy refer to chapter Specifications. With each transmitted time information, the SNTP server also sends information about its accuracy: Stratum: The stratum indicates over how many interacting NTP-Servers the used SNTP server is connected to an atomic or radio controlled clock.
  • Page 224 Time Synchronisation Fault Analysis If there is no SNTP signal for more than 120 sec, the SNTP status changes from “active” to “inactive” and an entry in the Event Recorder will be created. The SNTP functionality can be checked in the menu [Operation/Status Display/TimeSync/Sntp]: If the SNTP status is not indicated as being “active”, please proceed as follows: Check if the wiring is correct (Ethernet-cable connected).

    Protective Elements LVRT – Low Voltage Ride Through Available Elements: LVRT Why LVRT? - Motivation for LVRT The rapid development of distributed resources (DR) based on the renewable energy such as wind, solar and others has been changing the electric power system and concepts for its control, protection, metering and communication rapidly, too.
  • Page 416 Protective Elements Short Circuit Duration [s] Source: eBWK Bd. 60 (2008) Nr. 4 Authors: Dipl.-Ing. Thomas Smolka, Dr.-Ing. Karl-Heinz Weck, Zertifizierungstelle der FGH e.V., Mannheim, sowie Dipl.-Ing. (FH) Matthias Bartsch, Enercon GmbH, Aurich. Functional Principle of the LVRT From the grid operators point of view, a LVRT profile defines a voltage profile which a distributed generator, that is connected to the grid, should be able to ride through a low voltage event if the voltage at the point of common coupling remains above the LVRT borderline defined by the LVRT profile after a disturbance.
  • Page 417 Protective Elements Auto Reclosure controlled LVRT As already mentioned, the purpose of LVRT is to keep the DR connected to the grid in case of a non-permanent voltage dip/sag. For faults within the electrical power system by which auto-reclosing function is used to coordinate with the short circuit protections like overcurrent or distance protections, it is to expect that more than one voltage dips are coming one after another in a time period which is determined by the preset auto-reclosing dead times and protection relay operating times.
