  • Page 422: Time Synchronization

    Time Synchronization Time Synchronization TimeSync The user has the possibility to synchronize the device with a central time generator. 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.
  • Page 423 Time Synchronization Accuracy of Time Synchronization The accuracy of the device's synchronized system time depends on several factors: accuracy of the connected time generator used synchronization protocol when using Modbus TCP, SNTP or DNP3 TCP/UDP: Network load and data package transmission times Please consider the accuracy of the used time generator.
  • Page 424 Time Synchronization Selection of Timezone and Synchronization Protocol The protection relay masters both UTC and local time. This means that the device can be synchronized with UTC time while using local time for user display.

  • Page 429: Sntp

    Time Synchronization SNTP SNTP Important pre-condition: The protective relay needs to have access to an 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 430 Time Synchronization 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 the 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 431 Time Synchronization 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).

The static error accounts for transformer static magnetizing current and current measurement circuit calibration errors. The dynamic error may be caused by Tap Changing (OLTC) and by CT saturation caused by heavy fault currents. In addition, the static tripping characteristic can be modified temporarily at the User’s choice to prevent some nuisance tripping from the harmonic inrush during energization, over-excitation, or deep CT saturation.

    Protective Elements Out of Step Tripping [78] – Available elements: After disturbances in a power system, such as short-circuit faults and their tripping, power system oscillations (power swings) can happen between the generator concerned and the rest of the power system. Depending on the severity of system disturbances and the capability of the system reserve power a power system disturbance can either result in a controllable stable power swing, or extend to an unstable power swing.
  • Page 799 Protective Elements Impedance Location under Different System Conditions Under normal operation conditions the load impedances dwell within a load region shown in the following diagram, and no significant impedance change rate is expected by different load conditions. In case of a short-circuit fault in front of the generator, however, the impedances as viewed at the relay point change rapidly from the load region to a fault region which is located in very small range depending on the faulted distance to the relay point.
  • Page 800 Protective Elements Stable and Unstable Power Swings An out-of-step condition is recognized if an unstable power swing is detected. The criterion is that the rotor angle displacement (δ) exceeds 180°, or the measured impedance runs across the system impedance line on the impedance plane.

  • Page 802 Protective Elements The Case of a Typical Stable Power Swing In case of a stable power swing, as shown (in green color) in the diagram “Out-of-Step Characteristic and Single Blinder Scheme” above, the measured impedance can enter the MHO circle from its right-hand side. This is signaled via the output signal »Swinging«.
  • Page 803 Protective Elements Short-Circuit Fault During Power Swings It is important to distinguish between power swing events and short-circuit faults, to prevent unwanted OST tripping. This can be done by observing the change of the impedance, which is significantly faster for conventional faults than for power swings.
  • Page 804 Protective Elements Operating and Tripping Logic The principle implemented with this device is to issue the tripping command as soon as the second blinder is traversed; this is called the “Trip on Way out” (ToWo) scheme. The ToWo scheme traces a detected power swing and allows tripping after the first pole slipping, which results in less transient overvoltages on the breaker poles.

    Protective Elements Reconnection Module Available Elements: ReCon[1] ,ReCon[2] The reconnection function after a mains decoupling is based on the requirements of the VDE AR-N 4120 and the German directive „Erzeugungsanlagen am MS-Netz“ To monitor the reconnection conditions after a mains decoupling, a reconnection function has been implemented in parallel to the decoupling functions.
  • Page 970 Protective Elements After the decoupling functions have tripped so that the generator circuit breaker has been opened, some conditions must be fulfilled by the network operator before the reconnection of the power generating unit may be performed. These release conditions involve making sure that the mains voltages are within their valid value and frequency ranges.
  • Page 971 Protective Elements Voltage release by (self-) measured voltage values AND via remote control connection from the PCC This method can be used if the PCC is on the HV side. If the PCC is on the HV side the VDE AR-N 4120 (01/2015) permits connecting the power generation unit only if both the remote control release signal is present and the mains voltage connected to the generation unit is healthy.
  • Page 972 Protective Elements PCC in HV systems According to VDE-AR-N 4120 a reconnection of a Distributed Energy Resource to the grid is not allowed before the following conditions are fulfilled: The frequency of the mains/grid has to be between 47.5 and 51.5 Hz and the voltage between 93.5 and 127 kV (100 kV level).
  • Page 973 Protective Elements PCC in MV systems The German regulation „Erzeugungsanlagen am MS-Netz“ (BDEW, Issue June 2008 ) recommends to have a time delay (some minutes) between mains voltage recovery and reclosure after a trip of a decoupling system as a result of a mains failure.

  • Page 997: Lvrt - Low Voltage Ride Through [27(T)]

    The importance of LVRT will rise with the growing share of DRs within the electrical power system. Based on the technical requirements mentioned above, a LVRT protection function was developed for the HighPROTEC product line which covers the LVRT profiles (capabilities) defined by all relevant national and local grid interconnection standards.
  • Page 998 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 energy resource, that is connected to the grid, should be able to ride through in case of a low voltage event (voltage dip).
  • Page 999 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.
