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 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 Application Guide is intended to provide the users of VSTAB with insight into how to use the program for actual system studies. This document includes background on fundamentals of voltage stability as clarified during RP3040-1, and a description of VSTAB including details on modeling and analytical techniques. Much emphasis is placed on modeling requirements and methods, as a thorough understanding of these is essential before VSTAB can be successfully applied. This Guide also contains a number of worked examples to assist users in applying the program.
