Course detail

Distribution and Industrial Networks

FEKT-MMEZAcad. year: 2017/2018

The course deals with operation of distribution and industrial networks, both viewpoints of requirements for power quality and of the reliability of supply. The ways of operating and fault conditions of these networks and their protection are explained, as well as problems of distributed generation sources connection. Part of the course is devoted to the currently used standards for evaluating the reliability of power supply.

Learning outcomes of the course unit

Graduates of this course should be able to
- describe the operation and method of dimensioning of compensated networks,
- explain the differences in protection and ground fault localization methods in isolated and compensated networks,
- list the basic voltage characteristics,
- explain the voltage control process in a characteristic point of the distribution network,
- assess the influence of local sources on the quality of voltage at the point of connection
- define basic types overvoltages in the distribution network
- apply the wavelet theory on the calculation of surge arrester protection distance,
- describe the method of evaluation and indicators of reliability of power supply.

Prerequisites

Students should know the principles of unsymmetrical faults in power system, be able to describe the principles of overcurrent and distance protections. General knowledge is required at the level of bachelor's degree, but it is advisable to have completed course Distribution Equipments.

Planned learning activities and teaching methods

Techning methods include lectures, computer laboratories and practical laboratories. Course is taking advantage of e-learning (Moodle) system. Students have to write a single project/assignment during the course.

Assesment methods and criteria linked to learning outcomes

Students can gain up to 40 points from the total evaluation of the course for the project during the semester. Students have to obtain at least half of the maximum number of points.
The final exam consists of a written (max. 30 points) and oral (max. 30 points) parts. The written part of the examination tests students' ability to apply theoretical knowledge on the calculation of network fault conditions. The oral part is focused on their orientation in the topics defined by the course syllabus. Condition of the successful pass is to get at least half of the points in each of the final exam part.

Course curriculum

1. Different network concepts in neutral point treatment terms, its features and application.
2. Compensated network operation - construction and setting of Petersen coil.
3. Earth fault localization method, earth fault protections.
4. Voltage characteristics, cause of voltage drops and interruptions.
5. Voltage control in distribution network.
6. Distribution networks with distributed generation and their negative effects on energy quality.
7. Protection against overvoltage – types, application, parameters, protection distance of surge arrester.
8. Protection and automatic devices for distribution lines – overcurrent and distance protection, reclosing automatics.
9. Reliability indicators as a random quantity.
10. Continuity as a supply quality component. Evaluation of supply reliability.

Aims

The course should familiarize students with the design and operation of distribution and industrial networks. The aim is to introduce the fundamentals of network faults and how they are protected. The last part of the course is focused on the current standards used for evaluating the reliability of power supply.

Specification of controlled education, way of implementation and compensation for absences

Labs are compulsory; correctly excused absence can be replaced by arrangement with the teacher.
