ABSTRACT: The voltage stability is substantially a dynamic
stability, but the primary method which is more mature and engineering practical
to analyze the stability of voltage is still static analysis. The time-domain
simulation is an important measure in research of complex power grid. With the
development of full dynamic simulation technology, the research of dynamic
voltage stability by using full dynamic simulation program which is based on
time-domain simulation can be carried out. This paper uses full dynamic
simulation program in dynamic voltage stability research, lays special stress
on research in how generator over-excitation limiter functioned and influence
in dynamic voltage stability research, and raise 2 methods and steps to figure
out dynamic stable voltage in both over-excitation counted and not counted. The
simulation results of examples indicate the correctness and effectiveness of
these methods, and also fully verify the function and influence of generator
over-excitation limiter in full dynamic voltage stability research.
