An Open Platform for Rapid-Prototyping Protection and Control Schemes With IEC 61850

Abstract

Communications is becoming increasingly important to the operation of protection and control schemes. Although offering many benefits, using standards-based communications, particularly IEC 61850, in the course of the research and development of novel schemes can be complex. This paper describes an open source platform which enables the rapidprototyping of communications-enhanced schemes. The platform automatically generates the data model and communications code required for an Intelligent Electronic Device (IED) to implement publisher-subscriber Generic Object-Oriented Substation Event (GOOSE) and Sampled Value (SV) messaging. The generated code is tailored to a particular System Configuration Description (SCD) file, and is therefore extremely efficient at run-time. It is shown how a model-centric tool, such as the open source Eclipse Modeling Framework, can be used to manage the complexity of the IEC 61850 standard, by providing a framework for validating SCD files and by automating parts of the code generation process. The flexibility and convenience of the platform is demonstrated through a prototype of a real-time, fast-acting load shedding scheme for a low-voltage microgrid network. The platform is the first open source implementation of IEC 61850 which is suitable for real-time applications such as protection, and is therefore readily available for research and education.

Centralised busbar differential and wavelet‐based line protection system for multi‐terminal direct current grids, with practical IEC‐61869‐compliant measurements

“…These could include IEEE 1588 frames and data from other measurement locations; assuming a maximum of four simultaneous competing frames and a transmission delay of 0.58 µs per frame [23], the maximum queuing delay is 4 × 0.58 µs. t M U and t CC can be estimated as 12 µs and 9.5 µs, respectively, based on the measurements in [24] for approximately double the frame size, but this depends on the performance of the platform. Combining all of these factors, the worst case delay can be estimated as: Further delays are introduced by the protection system and they arise from the window-based processing required by the fault detection signal calculation and DWT.…”

Enabling Efficient Engineering Processes and Automated Analysis for Power Protection Systems

“…Therefore, protection settings data can be stored alongside other system data presented in a SCL file, which facilitates data integration. 6) The SCL format is formally defined by an XML schema [26], which allows the validation of SCL files to be conducted automatically [27]. The generation and manipulation of an SCL file can be automatically performed by model-centric software such as the Eclipse Modelling Framework (more details are provided in Section III-B).…”

“…A similar application of this tool is described in [27]. The exporting step is performed by the SCL Creator, as shown in Fig.…”

“…An example where specific low-level communication code is generated is presented by Blair et al [33]. In their approach C code is automatically generated based on IEC 61850 SCL files.…”
