Transient stability enhancement and voltage regulation of power system using I/O feedback linearization technique
Bevrani, Hassan (1997) Transient stability enhancement and voltage regulation of power system using I/O feedback linearization technique. In 12th International Power System Conference-PSC, Tehran, Iran.
To maintain a high degree of reliability, the impact of major disturbances, such as a large sudden fault, should be considered during power system stabilizer design. The problem of designing controllers to prevent an electric power system losing synchronism after a large sudden fault is of great importance in power system design.
The conventional stabilizer designs based on approximate linearization models are not adequate for large disturbances. When a large fault occurs, the behavior of the system changes a lot, and in many cases a linear controller cannot maintain adequate stability.
In this paper, by using the input-output feedback linearization technique and asymptotic output tracking theorem, a novel excitation control system is resented. Improvement of transient stability and voltage regulation of a single machine infinite bus power system in the presence of a symmetrical three phases short-circuit fault is considered as a test example.
The simulation results show that the power system can keep transiently stable and achieve good post fault voltage regulation with the proposed nonlinear controller.
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
