<p>PURPOSE:To estimate power demand of a traffic system accurately by determining power demand of each load based on data fed from an operating condition input section, with reference to the content stored in a load estimate data storing section, and summing thus determined power demand for an objective section. CONSTITUTION:An operating condition input section 1 receives operating condition data of each train and other train data as attributes. A load estimating data storing section 3 stores a table showing the correspondence between power demand and train position or estimating time for every type of train. An estimated train power calculating section 4 executes calculation of power demand for each train based on operating condition calculating conditions derived from input information fed from the operating condition input section 1 with reference to data stored in the load estimation data storing section 3. An estimated power integrating section 7 then determines the sum of estimated power demand for all objective train.</p> |
