Abstract

The system integrity and reliability is a major task of transmission system operators (TSOs). Different tools are available to drive a secure power system. But most of them missed the assessment of the influences of protection systems on the system security. Therefore we introduced the Dynamic Protection Security Assessment (DPSA). Protection systems like distance protection relays were included in transient stability analyses. The impact of these were analysed based on different indices which assessed the number of unwanted operation, number of pickups and the amount of undesired lost load. By taking several contingencies into account, the DPSA gave a ranking of critical relays which were susceptible to unwanted operation during transient stability simulations. Two case studies showed that power swing blocking is a suitable measure to prevent the system from blackouts, but it was not always useful. Especially during loss of synchronism of one generator or a coherent group, a dedicated system split prevented the grid from total blackout.
