EH2741 Communications & Control in Electric Power Systems

Transcription

1 Version September 2014 EH2741 Communications & Control Course Memo 6 ECTS credits

2 Overview Control and operation of power systems is a very large and comprehensive topic including many different fields ranging from power system instrumentation to power system modelling and control systems theory. The information and control systems needed to operate the power sytem, are so tightly integrated with the physical power system, together they constitute a cyber-physical system. This introductory course provides a wide perspective on the field, opening for continued studies in specialised subjects. The course is focused on design, implementation and use of information and control systems for control and operation of the physical power system. Course Objectives The objective of this course is to give an overview of technologies and concepts used for communication and control of power systems in a wide sense, including generation, transmission and distribution of electric power. After completing the course, the participants shall be able to: Describe the functions of the primary equipment in the power system that is relevant for protection, automation and control Analyze substations and simple power systems in terms of reliability protection, automation and control needs. Describe the function and architecture of information and control systems used for protection, automation and control of power systems. Describe the function and architecture of communication systems used for information & control systems for power system control. Describe the importance of information & control systems for the ability to connect large amounts of renewable power sources. Analyze and develop basic systems for substation automation and protection. Analyze and develop basic information & control systems for system-wide control from control rooms, e.g. SCADA systems and EMS applications. Construct a state estimator for power systems. Describe relevant interoperability standards in the field, such as IEC Describe the threats and risks associated with the use of information & control system for controlling the electric power system, known as Cyber Security. Prerequisites The course has no explicit pre-requisities, but it is assumed that course participants have completed a Bachelors degree in Electrical Engineering, computer science or related topic and are eligible for studies on the Master level. Course Structure The course consists of three blocks, these are: Substation Automation, SCADA & Wide area communication, and Energy Management systems. Each block includes lectures, project assignments, and lab work and a voluntary test. In addition, during the course, a study visit and guest lectures by industry experts will be arranged. Each course block consists of 2 ECTS credits. 2

3 Lectures and Exercise sessions The lecture series constitutes 15 lectures and 5 workshops covering the entire subject area. There are also 2 guest lectures whose content will NOT be included in the tests. Participation in the lecture series is recommended. For each lecture there is recommended reading, either a book chapter excerpt or scientific articles. It is highly recommended that course attendees read these texts before the lectures based on the provided reading guidance. Please note that contents from the reading materials ARE included in the tests. During the course, voluntary project hours are arranged. During these sessions, the students could work for their assignments in the classroom and teachers are available to answer questions. Project Assignment The project assignment involves three parts, Part 1, Part 2 and Part 3 and in addition a final presentation where the complete project is presented orally. In part 1, students are required to design a substation automation system including selecting measurement devices, designing protection scheme, and communication substation automation. Part 1 is concluded with a practical configuration assignment, in which parts of the designed system is implemented in real controllers In part 2, students are trained to design an information and communication systems architecture for communication between substations and control centres and perform basic calculations in terms of corresponding data volumes for the projected communication channels. Part 3 involves designing a State Estimator, which is the key application for Energy Management Systems (EMS) in Electric Power control centres. The students groups are also expected to at the end of the course give a 20-minute presentation about their entire project assignment. The project is conducted by students in groups of 4 students per group. Power System Control Lab (group) At the Power system control lab, students works in groups to solve set of typical power system control problems using the power system simulator ARISTO. The lab requires no specific preparation, and is conducted in the lab at the Department of industrial information & control sytsems, Osquldas väg 10 floor 7 (Q building). SCADA & Wide Area Communication Lab (group) The SCADA & Wide Area communication lab involves configuring a Wide Area communication network to allow data capture and sending commands to field devices through a simulated communications network. This lab is performed in the same groups that the students were assigned for the project assignments and will be held at the department lab on Osquldas väg 10, floor 7 (Q building). Study Visits Study visits are not completely finalised at this time and more details will be provided during the lectures. 3

4 Tests The course also contains three volontary tests covering the theoretical concepts covered in the lectures, exercises and projects. The tests are individual, and voluntary. Participation in the tests is however a pre-requisite for achieving higher grades. Course Administration All course materials can be downloaded at KTH social and project assignments must be submitted to [email protected] before the corresponding due dates. Course updates, schedule changes etc. will continually be posted on the KTH social, please check regularly. Literature The literature of the course consists of a very basic text book complemented with a set of scientific papers and excerpts that provide more detail and insight into different aspects of the field. The main textbook is: Electrical Network Automation and Communication Systems, 2003 by Cobus Strauss. In addition, students will be provided with written hand-outs at start of the course with material that complements the coursebook. A.
