Title: Automatic Integration of a Dynamic Security Assessment System into a Power Grid
Language (ISO): en
Abstract: Today’s power grids must utilize more energy than they were originally planned for. Hence, they are slowly reaching their stability limits and that causes an increased risk of blackouts in electrical networks. To avoid such critical situations in the control room the system dynamic state must be assessed as quickly as possible and its personnel have to react to it early enough. This kind of evaluation could be done by the so-called Dynamic Security Assessment system which is able to assess the dynamic state of the electrical network online. This paper presents completely automatic methods of the dynamic security assessment system integration into a power grid, functionality testing of the Over Excitation Limiter (OXL) - which is implemented in the Automatic Voltage Regulator (AVR), and the electrical grid plausibility check.
