Abstract	:	Stability is one of the most important problems in power system operation andcontrol. Voltage instability is one type of power system instability that occurs when thesystem operates close to its limits. Progressive voltage instability, which is also referredto as Voltage Collapse, results in loss of voltage at certain nodes (buses) in the system.Voltage collapse, a slowly occurring phenomena leading to loss of voltage at specificparts of an electric utility, has been observed in the USA, Europe, Japan. Canada, andother places in the world during the past decade. Voltage collapse typically occurs onpower systems which are heavily loaded, faulted and/or have reactive power shortages.There are several power system's parameter changes known to contribute to voltagecollapse. The most important contributors to voltage instability are: increasing load,generators or SVC reaching reactive power limits, action of tap-changing transformers,line tripping, and generator outages. The differences between voltage collapse and lack.....-....,....-...,..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..
