Due to the increasing complexity of our electrical power systems, the need for highly selective protection is increasingly being fulfilled by the use of teleprotection schemes or line differential protection. To test such distributed protection systems properly, a distributed end-to-end test with synchronized injection is required. The first challenge for such a test is the correct calculation of...
Przedstawiono nowe możliwości testowania układów zabezpieczeń różnicowych linii i telezabezpieczeń w sieci WN z wykorzystaniem testerów sterowanych zdalnie.
The paper presents a brief overview of the standard IEC60255–121 and focusses on the challenges and advantages of using transient simulation for assessing protective relays. The importance of the use of statistical methods to investigate the behaviour of algorithms is discussed. Finally a new solution for performing these kinds of tests is introduced.
