The main advantage of the variable speed power generation systems with slip-ring induction generator related to cage or synchronous generator is low power and low costs of the power electronics. As the speed range is limited the power converter can be designed on few percent of the generator power, that provide lower losses and costs and higher efficiency. The Direct Voltage Control method of slip ring induction generator is presented in this paper. This method bases on stator voltage vector feedback, that permits the generator can operate as a stand-alone set e.g. in island power systems. Moreover an autonomous operation mode provide the grid connected generator is useful even after the mains outage and can supply isolated part of a grid load. The Direct Voltage Control method uses a space vector theory. A stator voltage vector represented in the reference frame rotating with synchronous speed has fixed magnitude and position when the stator voltage amplitude, frequency and phase are fixed. To obtain the fixed values of the voltage vector amplitude and position, two voltage regulators are applied. One of them based on reference and actual stator voltage amplitude is responsible for rotor current amplitude. The second regulator based on reference and actual stator voltage angle referred to synchronous frame is responsible for rotor current frequency. Applied stator voltage control method do not use any information about the rotor speed or position, therefore it can be called sensorless. Moreover an instantaneous value of the generated stator voltage is controlled that provide not only fixed voltage frequency and amplitude but also controlled voltage phase. This is an important advantage in grid and generated voltage synchronization process.
