The objective of this unit is to impart to students a detailed knowledge of the imperatives and configurations used for remote monitoring of power systems, particularly communication hardware and protocols. Information presented in this unit will also include: the importance of vendor-independent systems; how this objective is achieved by various standardisation efforts, including IEC standard 61850; and, the role played by OPC specifications. Students will complete a project covering the design of a power system monitoring facility for a distribution network of a large city.

  1. Explain the need/importance of remote monitoring and control of large power networks, and the emphasis on security.

  2. Apply the basic principles of industrial data communications to a range of scenarios.

  3. Evaluate and compare the communication protocols adopted in power network monitoring systems according to application.

  4. Demonstrate using practical examples how the standardisation of communication devices and protocols can achieve vendor independent systems.

  5. Demonstrate the application of OPC data access specifications in power network monitoring systems.

  6. Analyse the role of IEC 61850 standards for power system automation.
