    Abstract

    The paper discusses the dynamic characteristics of a three level ±4mvar solid state var compensator which is built and will be used for dynamic reactive power compensation in a wind farm. An investigation has been carried out of the influence of the compensator reactor, the DC intermediate voltage capacitor and the losses of the compensator for its speed of control, specially its response to fast phase shift in the grid. Furthermore the need for DC midpoint control will be compared with the inherent stabilisation. The harmonics made by the midpoint control will be compared with the harmonics without midpoint control. The simulations were made by an EMTDC model build as part of my Ph.D. proj-ect, the compensator is being made by SIEMENS and the control in the model was built together with UMIST.
