Title Proper : VOLTAGE COLLAPSE PREDICTION FOR INTERCONNECTED POWER SYSTEMS
Note : This document is digital این مدرک بصورت الکترونیکی می باشد
Abstract : A steady state analysis is applied to study the voltage collapse problem. The modal analysismethod is used to investigate the stability of the power system. Q-V curves are used to confirm theobtained results by modal analysis method and to predict the stability margin or distance to voltagecollapse based on reactive power load demand. The load characteristics are considered in thisresearch. Different voltage dependent loads are proposed in order to be used instead of theconstant load model. The effect of induction machine load is considered in this study. The load isconnected to several selected buses.The analysis is performed for three well-known system; Western System Coordinating Council(WSCC) 3-Machines 9-Bus system, IEEE 14 Bus system and IEEE 30 Bus system. The modalanalysis technique is performed for all systems using the constant load model, the voltagedependent load models and induction machine load model. Then, the most critical mode isidentified for each system. After that, the weakest buses, which contribute the most to the criticalmode, are identified using the participation factor. The Q-V curves are generated at specific busesin order to check the results obtained by the modal analysis technique and to estimate the stabilitymargin or distance to voltage collapse at those buses...,....-...,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
