Course Content

Due to the enormous importance of the safe supply of electrical energy, the electrical systems for the transport and distribution of energy and power must be resilient to faults. In the event of any type of fault (loss of insulation, controller faults, external influences, ...) and for any possible fault location (line, transformer, generator, ...), suitable protection systems detect this fault as quickly as possible and selectively eliminate it.

Starting from the choice of the necessary and suitable technical procedures, their function-relevant parameters must be determined, the corresponding protection devices defined, parameterised and finally activated in order to ensure the integrity of the system.

The main content of this course is the introduction to the basic protection methods, the different protection tasks (short-circuit protection, earth fault protection, system protection, ...) and the different protection implementations (overcurrent protection, distance protection, differential protection, ...) including their settings and functionality limits. For this purpose, basic knowledge and methods as well as their handling are taught in order to gain knowledge about the typical concepts of electrical network and system protection and their implementation.

Course Goals

The participants have an overview of tasks, strategies and the usual procedures of protection in electrical power systems. They are able to design the appropriate procedures for a given type of fault and determine the functional parameters.

Concrete objectives are:

• I know the functioning of overcurrent, differential, distance, earth fault and system protection procedures.
• I can specify the function parameters and their limits and determine setting values.
• I can assess the functionality of a specific solution in a given fault scenario.

Previous Knowledge

Fundamentals of power systems, basic knowledge of the operating equipment of power systems, fundamentals of fault calculation in electrical systems.
