Generator Digital Regulators Distributed Generation Plants

摘要

The article provides results of power supply systems modes' computer-based research conducted with distributed generation (DG) plants equipped with digital automatic voltage regulator (AVR) and automatic speed governor (ASG). Look-ahead algorithms were used to enhance control quality. Analysis of digital regulators effect on transient processes indices for disturbances of power supply system operating mode. The results of computer-based modeling performed in MATLAB system indicated that the use of look-ahead algorithm al-lowed to significantly improve controllers damper properties and reduce the object's persistence during DG plants transition to island operation, and when powerful asynchronous motors are started.
