Voltage stability/security assessment and on-line control
- Ontario Hydro, Toronto, ON (Canada)
Project RP3040-1 was initiated in 1989, and concluded with the release of the Voltage Stability analysis program, VSTAB, in 1992. VSTAB is a production grade program for voltage stability assessment of large complex power systems. During the course of the RP3040-1, much effort was spent in developing a clear understanding of voltage stability and in defining the special modeling and analytical techniques required to accurately capture the phenomenon through simulation. The result was the development of new steady state methods which can complement the dynamic simulation methods currently available with EPRI's Extended Transient/Midterm Stability Program (ETMSP). VSTAB uses an enhanced powerflow combined with a specially developed modal analysis algorithm to provide information regarding both the proximity to, and mechanism of, voltage instability. The program is fast, easy to use, and comprehensive in both modelling and analysis features. This Users Manual is intended to provide the users of VSTAB with clear instructions on how to use the program. This document includes details on data input formats and program control. For insight into how to apply the program, users are directed to the VSTAB Application Guide which provides background on the fundamentals of voltage stability as clarified during RP3040-1, and a description of VSTAB including details on modeling and analytical techniques.
