Problems solved by technology

When the time constant in the differential equation is small relative to the wavelength of the fundamental frequency component, the details of the model describing many complex operations of the dynamic element cannot be directly implemented in PSS / E due to bandwidth limitations

There are many literatures in the field of wind power research, which describe the corresponding models for various types of wind turbines that have been put into operation, but most of them cannot be easily implemented in PSS / E, because the models contain The small time constants associated with the control of wind turbines cannot be taken into account by the fundamental frequency component simulation algorithm used by PSS / E
