Model verification for analysis of wind power impact to transient stability in isolated power system using combined relay protection and dynamics modelling approach

Usually, when performing network dynamic studies fault duration times and network configuration are selected based on predefined conditions. In this paper, the approach is to complement the conventional approach by considering actual relay protection operation. In addition, also possible failures of relay protection and circuit breaker operation are taken into account, i.e., additional fault clearing time causing different transient behaviour, is included. This paper gives an overview and discussion about the development of combined relay protection and dynamics modelling methodology and it is focused on the verification of relay protection and dynamic electromechanical transient model against actual field measurements during the wind power plant commissioning tests.
