Abstract

Modern electrical substations require communications networks to operate safely and efficiently. IEC61850 is a communications standard which has been developed to allow interoperable, high speed substation communications between substation equipment, including protection relays. This communications network aims to replace hard-wired signaling connections between equipment in the substation, enabling a reduction in labour during installation, and an increase in reliability of the interconnections between devices.

Still relatively new, the penetration of IEC61850 compliant systems is varied throughout the industry. Increasing implementation as the technology develops will require the training of staff to commission and maintain these systems. An easily accessible, low cost simulator will allow staff to interact with and be trained on a simulated system prior to working on live in-service equipment.

This project builds on the prior work of Michael Zillgith, who has developed an open source C programming library which allows access to an IEC61850 compliant stack. The library features include Generic Object Oriented Substation Event (GOOSE) message subscription/publishing and Sampled Measured Values (SMV). The simulator has been implemented on a Raspberry Pi 3 (Model B) with a touchscreen interface programmed using QT Creator, a C/C++ Integrated Development Environment.

This project has developed simulators for the most common types of devices on an IEC61850 network. Simulating both the process and station bus topology, typical network traffic on both buses is simulated using demonstrations of typical substation connections. Three simulation environments have been developed to allow the technical user to interact with familiar types of device connections, which would normally be seen within a substation environment.

Six types of device have been developed, including MMS control, Bay Controller IED, Protection Relay IED, Process Bus I/O, Process Bus Merging Unit, and Network Timing Devices. Several of these units also have other versions to represent different devices on the simulated substation networks.
