Siprotec 7VE6 Multifunction Paralleling Device Of Siemens Siprotec 4

Ask For Price
Product Price :Get Latest Price
The 7VE61 and 7VE63 paralleling devices of the SIPROTEC 4 family are multifunctional compact units used for paralleling power systems and generators.

Their technical design ensures highly reliable paralleling due to their 1-channel or 2-channel measurement method and their hardware design. This is supported by numerous monitoring functions. The units automatically detect the operating conditions. The response to these conditions depends on settings. In "synchronous network switching" mode, the frequency difference is measured with great accuracy. If the frequency difference is almost zero for a long enough time, the networks are already synchronous and a larger making angle is permissible.

If the conditions are asynchronous, as is the case when synchronizing generators, the generator speed is automatically matched to the system frequency and the generator voltage to the system voltage. The connection is then made at the synchronous point, allowing for circuit-breaker make-time.

The 7VE61 paralleling device is a 1-channel unit (paralleling function + synchro-check) for use with small to medium-size generators and power systems. It is more reliable than 1-channel paralleling devices. It can also be used for synchro-check, with parallel operation of three synchronization points.

For larger generators and power systems with high reliability requirements, the 2-channel 7VE63 is recommended. Two independent methods decide on the connection conditions. The unit also has the full control functions of the SIPROTEC 4 family. Voltage and frequency functions (V>, V<, f>, f

The integrated programmable logic functions (continuous function chart CFC) offer the user a high flexibility so that adjustments can easily be made to the varying requirements on the basis of special system conditions.

The flexible communication interfaces are open to modern communication architectures with control systems.

Basic functions :
  • High reliability with a two-out-of-two design (1 ½ channels in 7VE61 and 2 channels in 7VE63)

  • Paralleling of asynchronous voltage sources

  • Balancing commands for voltage and speed (frequency)

  • Paralleling of synchronous voltage sources

  • Synchro-check function for manual synchronization

  • Parameter blocks for use on several synchronizing points (7VE61 max. 4 and 7VE63 max. 8)

Additional functions
  • Consideration of transformer vector group and tap changer

  • Synchronization record (instantaneous or r.m.s. record)

  • Commissioning support (CB-time measurement, test synchronization)

  • Browser operation

  • Full control functionality of SIPROTEC 4

The 6MD63 bay control unit is a flexible, easy-to-use control unit. It is optimally tailored for medium-voltage applications but can also be used in high-voltage substations.

The 6MD63 bay control unit has the same design (look and feel) as the other protection and combined units of the SIPROTEC 4 relay series. Configuration is also performed in a standardized way with the easy-to-use DIGSI 4 configuration tool.

For operation, a large graphic display with a keyboard is available. The important operating actions are performed in a simple and intuitive way, e.g. alarm list display or switchgear control. The operator panel can be mounted separately from the relay, if required. Thus, flexibility with regard to the mounting position of the unit is ensured.

Integrated key-operated switches control the switching authority and authorization for switching without interlocking.

  • Siprotec 7SD610 Universal Differential Protection Relay, Siemens Relay
Ask For Price
Product Price :Get Latest Price

The 7SD610 relay is a differential protection relay suitable for all types of applications and incorporating all those functions required for differential protection of lines, cables, and transformers. Transformers and compensation coils within the differential protection zone are protected by means of integrated functions, which were previously to be found only in transformer differential protection. It is also well-suited for complex applications such as series and parallel compensation of lines and cables.

 

It is designed to provide differential and directional backup protection for all voltage levels and types of networks. The relay features high speed and phase-selective short circuit measurement. The unit is thus suitable for single-phase and three-phase fault clearance.

 

Digital data communication for differential current measurement is effected via fiber-optic cables, networks or pilot wires connections so that the line ends can be quite far apart. The serial protection interface (R2R interface) of the relay can flexibly be adapted to the requirements of all existing communication media. If the communication method is changed, flexible retrofitting of communication modules to the existing configuration is possible.

 

Apart from the main protection function, i.e. the differential protection, the 7SD610 has a full range of configurable emergency and/or backup protection functions such as phase and earth over current protection with directional elements if voltage transformers are connected. Overload, under and over-voltage/frequency and breaker failure protection round off the functional scope of the 7SD610.

Protection Functions

  • Differential protection for universal use with power lines and cables on all voltage levels with phase-segregated measurement (87L)
  • Two line ends capability
  • Suitable for transformers in protected zone (87T)
  • Restricted earth-fault protection (87N) if a transformer is within the protection zone
  • Well-suited for serial compensated lines
  • Two independent differential stages one stage for sensitive measuring for high resistance faults and one stage for high current faults and fast fault clearance
  • Breaker-failure protection (50BF)
  • Phase and earth overcurrent protection with directional element (50, 50N, 51, 51N, 67, 67N)
  • Phase-selective intertripping (85)
  • Overload protection (49)
  • Over/undervoltage protection (59/27)
  • Over/underfrequency protection (81O/U)

      The operating and parameterization program Reydisp is the basic software used for the configuration of the Reyrolle range of protection relays. It provides a user-friendly tool with the built-in tutorial, help file, and manual which reduces the requirement for additional training. This intuitive software allows the viewing and editing of settings, viewing fault information, configuring the relays language, IDMT curves, and communication data points.

      When configuring Reyrolle devices with the optional IEC 61850 Ethernet communication ports the Reydisp Manager PC software should be used. This software provides the additional configuration tools to ensure an efficient 61850 engineering process.

      The Reydisp Manager can also be used with the latest releases of the 7SR210 and 7SR220 devices.

      Reydisp Evolution and Reydisp Manager are free of charge and can be downloaded directly from this site. The PC-program works with common Windows operating systems incl. Windows XP.

      Reydisp Evolution is a Windows based suite of software tools, providing the means for the user to fully configure the relay and is common to the entire range of Reyrolle protection relays.

      The setting configuration tool allows the user to apply settings, interrogate settings and retrieve events and disturbance waveforms from the device.

      The Language Editor software gives the user the ability to customize the text displayed in the relays, Menu structure, and instrumentation views.

      The tool allows a language file to be created and transferred to the relay containing any Western European characters. To facilitate easier interfacing to a substation the relays default Protocol configuration may be modified using the communication editor software tool. The communication editor is a PC-based software package provided within the Reydisp suite which allows modification of the data points available from the relays associated with the IEC 60870-5-103, DNP 3.0 and MODBUS Protocols.

      The Curve Editor software allows the creation of IDMTL curves for Reyrolle relays, to allow the user to have more flexibility when grading with other devices. It can import existing curves, create new curves from templates and send the curves to the relay.

      Further Features:

      • All of the software tools contain the basic tools for saving, printing data and opening template files.

      Setting Editor:

      • Import and export of parameter sets
