A new power stabilization control system based on making use of mechanical inertia of a variable-speed wind-turbine for stand-alone wind-diesel applications

In this paper is described the development of a new wind-diesel generator system which is based on standard diesel generators connected to MADE AE-56 wind turbines. Such wind-turbines have variable-speed, variable-pitch operation and they are regulated under a special patented control algorithm, devoted to stabilization of grid frequency. One of the most important advantages deduced from the behaviour of the complete system is the continous improvement of the power quality, in terms of frequency and voltage stabilisation as it is shown from the exposed results. This is a required feature in islanding power systems, which is achieved with the presented stand-alone generation system. The control algorithm is being based in DSP operation and the complete system is being built with MADE´s technology.
