Energy conservation by improved control of bulk power transfers on interconnected systems

摘要

This invention introduces the concept that on an interconnected electric power system, the area-caused components of memory parameters system time deviation and the total inadvertent interchange of each constitutent control area are separable and measurable. Methods and means are disclosed for separating each of the components and determining its magnitude, utilizing known or measurable parameters, thereby providing new long-desired area memory parameters which are precise measures of the control performance of each area. The portion of system time deviation and the portion, designated primary inadvertent, of total area inadvertent interchange caused by an area's own regulating deficiencies, and the portion, designated secondary inadvertent, of total area inadvertent interchange caused by regulating deficiencies of each remote area, are identified. Certain of the components are then utilized in their respective areas to provide unilateral simultaneous corrective control of said area's component of system time deviation, said area's primary component of area inadvertent interchange, and the secondary inadvertent components of area in advertent interchange of all remote areas caused by the regulating deficiencies of said area, doing so more effectively, more equitably and more economically than is possible with prevailing conventional control techniques.
