    Section 2 1MRS757647 C IEC 60870-5-103 overview Section 2 IEC 60870-5-103 overview IEC 60870-5-103 standard IEC 60870-5-103 is defined as a companion standard for the informative element of protection equipment. While the official IEC 60870-5-103 standard dates back to 1997, the protocol has its roots in the VDEW6 communication protocol from the late 1980’s.

    Section 2 1MRS757647 C IEC 60870-5-103 overview single-function protection IED. The 620 series IEDs in turn are multifunctional protection and control IEDs whose internal data model is based on the IEC 61850 standard. Interoperability list The standard requires the IEC 60870-5-103 device to provide an interoperability list, which actually is more an interchangeability list.

Depending on the communication card, the optical connection may be available only for one COM port (1 or 2).

  • Page 19: Asdu 2 Type Fault Number And Relative Time Data

    Section 3 1MRS757647 C Vendor-specific implementation 3.3.2.1 ASDU 2 type fault number and relative time data In addition to the absolute event time stamp, the ASDU 2 type requires that the message also contains a fault number and relative time data. However, these are not available in the IEC 61850 data model.

  • Page 20: Class 1 Event Overflow

    Section 3 1MRS757647 C Vendor-specific implementation The difference between a readable/writable object and a write-only object is not visible in the Communication Management tool of PCM600. An object is of write-only type if it is located on an IEC 61850 Oper.ctlVal data attribute. In this case, the GI enabling and other possible event configuration settings are meaningless.

  • Page 21: Class 1 Data Message Priorities

    Section 3 1MRS757647 C Vendor-specific implementation 3.3.2.5 Class 1 data message priorities User command responses (highest priority) Class 1 change events Disturbance file transfer messages General interrogation data responses (lowest priority) Disturbance file transfer increases the overall response time for Class 1 change events on the IEC 60870-5-103 interface.

    Section 3 1MRS757647 C Vendor-specific implementation coding of double-pole objects. The possible values are “00” for None, “01” for OK and “11” for Alarm. In case of a two-position “OK-Alarm” LED, the LED area 2 data can be configured to show normal Off/On DPI-data using the double-point extended value to single- point value conversion.

  • Page 23: Value Interpretation

    Section 3 1MRS757647 C Vendor-specific implementation By default, most of these objects are not in use. The predefined private function types and information numbers for these objects can be edited freely. 3.3.3.2 Value interpretation According to the IEC 60870-5-103 standard, the TypeID 4 value coding format is 32- bit floating point.

  • Page 24: Control Operation Rejections

    Section 3 1MRS757647 C Vendor-specific implementation The relay cannot distinguish if the IEC 60870-5-103 client is of the Station or Remote (NCC) type. However, it is possible to locally reject the control operations on the IEC 60870-5-103 client side based on this indication and information about the client type (NCC or Station).

  • Page 25: Other Class 2 Measurand Frames

    Section 3 1MRS757647 C Vendor-specific implementation relates to current and voltage values only. The allowed scale factors, actually meaning |max values| of per unit coded measurands, are 1.2 or 2.4. The IEDs support all five interchangeable Class 2 measurand frames defined by the standard. Table 6: Interchangeable Class 2 measurand frames Frame...

  • Page 26: Selection Of Class 2 Frame

    Section 3 1MRS757647 C Vendor-specific implementation See the list of available measurands from the product-specific point list manuals. 3.3.5.3 Selection of Class 2 frame The Class 2 frame is selected with parameter Frame1InUse n. The user can select between the user-defined frame 0, standard frames 1 to 5, or IED-dependent frames 6 and 7.

  • Page 27: Energy Counters

    Section 3 1MRS757647 C Vendor-specific implementation Fault records The fault record needs to be separately configured for the desired registration actions. For example, registrations can be defined to be made only at operate (trip) situation, or also at any start on/off situation. The fault record function component contains all registration object values that could have potentially been used by the relay type in question.

  • Page 29: Interpretation Of The Counter Values

    Section 3 1MRS757647 C Vendor-specific implementation in parallel can be connected to a binary output and wired to other units, a broadcast freeze can be achieved. 3.3.6.2 Interpretation of the counter values The ASDU 205 counters are derived from the corresponding IEC 61850 counter objects.

  • Page 30: Other Iec 60870-5-103 Data

    Section 3 1MRS757647 C Vendor-specific implementation Example 2 The legacy protocol default mappings are a selection of the most important signals produced by the IEC 61850-based protection relay applications. The manufacturer’s selection of important signals may not always serve every customer. Any non-protocol-mapped internal signal can be freely connected to a general- purpose input object via the Application Configuration tool.

  • Page 31: Device Identification

    Section 3 1MRS757647 C Vendor-specific implementation 3.4.2 Device identification 3.4.2.1 Device function type The IEC 60870-5-103 standard requires that an IED is identified as a certain Device type. The standard has only the following single functional device types: • 128 distance protection •...

  • Page 32: Time Synchronization

    Section 3 1MRS757647 C Vendor-specific implementation 3.4.3 Time synchronization Time synchronization over IEC 60870-5-103 is supported. This requires that the IED’s global Time Sychronization Source parameter (in Configuration/Time/ Synchronization/Synch source) is set to "IEC 60870-5-103" mode. If some other time synchronization source is configured for the IED, the IEC 60870-5-103 time synchronization messages are rejected.

  • Page 33: Disturbance Recorder Channel Identification

    Section 3 1MRS757647 C Vendor-specific implementation The IEC 60870-5-103 disturbance recorder file directory can be requested by the client at any time by asking GI data. In addition, the disturbance recorder file directory should be sent spontaneously by the IED (through Class 1 report) to the client if the directory structure changes.

It depends on the IED type if all the disturbance recorder channel signals are available or not.

  • Page 35: Disturbance Recorder Transfer

    Section 3 1MRS757647 C Vendor-specific implementation 3.5.4 Disturbance recorder transfer When the IEC 60870-5-103 client selects a disturbance recording to be transferred, the corresponding disturbance recording data is internally fetched from the IED’s native disturbance recorder file, cached and converted into IEC 60870-5-103 format. This operation may take some time depending on the size of the disturbance recorder file.

  • Page 36: Gi Optimization

    Section 3 1MRS757647 C Vendor-specific implementation 3.6.1 GI optimization The master should initiate a GI always after the IED has reported a Class 1 event buffer overflow. The IED starts then to send GI data through the Class 1 event buffer. As the standard defines, new events always have higher send priority than GI data in the IED’s Class 1 buffer.
