IEC 61850

NovaTech Substation Automation Solutions for IEC 61850

This webpage summarizes NovaTech OrionLX™ and Bitronics® products and solutions for IEC 61850. The focus is on how these products can be applied in electrical substations with both non-IEC 61850 legacy technology and the latest IEC 61850 technology. NovaTech products for IEC 61850 are summarized below.

Automation with Mixed Legacy Technology and IEC 61850 Technology.

The OrionLX™ Automation Platform is designed to bridge the latest IEC 61850 technologies with legacy technologies using configuration tools to convert protocols and create object models.

IEC 61850 Applications with NovaTech Products

 

iec-61850-legacy-scada-gateway

 

In the OrionLX™ configuration program (NovaTech Configuration Director or “NCD”) users define which points are to be acquired from the IED, and which points are to be presented to data clients, typically SCADA, HMI screen, Math and Logic, external databases, email clients, etc. Figure 4 below shows the points selected to be read from the Bitronics® M871 Recording IED. In this case, 149 input points have been selected from the 2503 points available. A search function and “MX” and “ST” point filter simplify data management in large applications.

Figure 5 below shows another NCD configuration screen showing the selected IEC 61850 points to be presented to a IEC 60870-4-104 SCADA Master. The selected points include the points obtained from the Bitronics M871 IED (using IEC 61850) and also diagnostic OrionLX points.

Using Orion Model Builder to Create User-Specific Device Models

The Orion Model Builder feature in NCD enables fast creation of user-specific Server Device Models. Logical Devices can be set up any way the user desires. An “IED Device” approach and “Substation Apparatus” approach are illustrated in Figure 8 below. Each Logical Device is populated by one or more Logical Nodes (measurement, protection, control, etc), then Data Objects and Data Attributes. Any point in the Orion real-time database can be dragged and dropped into these Logical Devices. The IEC 61850 user can define Logical Devices based on IEDs, substation apparatus, or any other way that best supports user practices.
