This paper presents a comprehensive computational representation of a variable speed Wind Energy Conversion Systems (WECS) and its connection to typical AC grid systems. The arrangement chosen for modelling purposes consists of a multipole synchronous generators units. This type of arrangement appears as a modern tendency to WECS composition. The paper content comprises basic information about the overall scheme structure, time domain modelling and computational implementation in the well known ATP platform. Using this approach studies involving transients, dynamic and steady state analysis can be then performed. Although these facilities are available, the case studies here considered are focused on the investigation of the relationship between specific wind and PCC voltage conditions and the final voltage and current forms produced at the AC busbar wind energy with distinct ramp and gust conditions are utilized so as to highlight the control action in limiting and optimizing the energy transference to the generators. In addition to this, the occurrence of non-ideal conditions to the PCC voltage and the overall interaction with WECS and AC system can be fully taken into account for power quality studies.
