Abstract

The use of asynchronized generators (ASG) in distributed generation plants allows obtaining the following positive results: increasing stability limits; expanding the ranges of reactive power regulation; simplifying synchronization processes with the network due to the ability to control the frequency and phase of the EMF; and ensuring the operation of the unit in the synchronous mode in case of one of the field windings damage.



The article describes the developed computer models of high-voltage and low-voltage ASG equipped with automatic excitation control systems on IGBT transistors allowing you to change the amplitude and frequency of the voltage. The studies were conducted in the MATLAB system using the Simulink and Sim Power Systems packages. The ASG autonomous operation modes were studied during load connection and load shedding. The results of comparing the operation of the electric network with a distributed generation unit operating on the basis of synchronous generators and ASG are presented, and the processes of synchronizing the ASG with the network are described. The simulation results of a stand-alone asynchronized generator showed that the use of a frequency deviation signal can reduce the deviations of the adjustable parameters in the load connection and disconnection modes, as well as when the ASG is turned on in the network by the self-synchronization method. When the ASG operates in parallel with the network, asynchronous generators operate stably with sufficiently large disturbances; in similar conditions, the dynamic stability of a system with synchronous machines is not provided. The developed system of automatic control of the excitation, as well as the proportional-integral-differential (PID) speed controller of the rotor of the asynchronized generator, smoothly adjust the set parameters, significantly reducing voltage and frequency fluctuations.


Keywords: distributed generation plants, asynchronized generator, automatic excitation and frequency controllers, power supply systems, operating modes, synchronization, modeling
