Abstract
The lecture presents the solutions applied in the current version INTROL-22 of the automatic voltage regulator (AVR) of the synchronous generator of the Nikola Tesla Institute of Electrical Engineering. In addition to the standard solutions defined by the current state of the art, the improved solution also contains algorithms that enable the application of AVR in the conditions of power facilities in power systems with remote nodes, as well as with a transmission system sensitive to transient instabilities and disturbances such as short circuits and frequent outages of parts of the system. The developed ARN also includes improved software for identifying the dynamic characteristics of the regulation system, for setting the parameters of voltage regulators, limiters and stabilizers of the power system, as well as for monitoring the variable states of the ARN in real time via a high-speed RS485 serial connection, and with specialized industrial communication protocols based on ethernet.
Keywords: Automatic voltage regulator, synchronous generator, advanced regulation and protection solutions, power system stabilizer, ethernet-based industrial communication protocols
Biography of the presenter
Dr. Đorđe Stojić was born in Belgrade, where he completed primary and secondary school. He enroled at the Faculty of Electrical Engineering in Belgrade in 1989, where he graduated, and obtained master’s and doctorate degrees in 1994, 1996, and 2004, respectively. Since 1994, he has been employed at the Nikola Tesla Institute, in the Center for Automation and Regulation, where he was involved in research and development projects within the design of hardware and software solutions, as well as control and measurement algorithms in solutions applied in the regulation of drives, primary regulation circuits of the synchronous generator, as well as in regulated power converters connected to the network.
