EH2740 Computer Applications in Power Systems, basic course 7.5 credits

Cost efficient operation of deregulated electric power system is completely dependent upon well functioning ICT systems to fulfill requirements on reliability and quality. These ICT systems are used for protection, measurement, monitoring and control of components and sub-systems, like power stations and substations. Additionally, the development towards Smart grids that can accommodate large amounts of renewable production and changing consumer patterns, including large scale use of electric vehicles gives the ICT systems an even greater role in the future power system.

The course covers the IT systems, technologies and standards that are constitute modern information and control systems used in the power system. Course content includes studies of secondary systems used for automation and protection in substation including the IEC 61850 standard; SCADA systems and communication solutions for Local and Wide Area Networks, including the IEC 61870-101/104 standard; technologies for information exchange and systems integration in the power industry including IEC 61968/61970 – the Common Information Model and also EMS application functions such as state estimation.

The purpose of the course is to introduce the use of Information and Control Technologies for Power System Management. The specific course goals are that the student shall be able to:

• Describe the functionality of primary equipment necessary for automation and control of power systems
• Analyze simple power systems from an automation and control perspective
• Describe the concept and use of the IEC 61850 standard for utility automation

·         Apply the IEC 61850 standard for utility automation to build simple automation and control systems for small power systems.

·         Describe the functionality of secondary equipment used for automation and control of power systems

·         Describe the concepts and structure of the IEC 61968/61970 standards for information exchange for power system control.

·         Apply the IEC 61968/61970 standard to information exchange needs in power system management

·         Describe the structure and design wide area communication solutions for power system control and operation.

·         Develop a simple Power State Estimator for power system control purposes.

Bachelor's degree (180 higher education credits), or equivalent qualifications. Documented proficiency in English corresponding to English B/ English 6.
