This paper presents a study to estimate the composition of an electric load, i.e. to determine the amount of each load class by the direct measurements of the total electric current waveform from instrument reading. Kalman filter algorithm is applied to estimate the electric load composition on a consumer side of a distributed power system. The electric load supplied from the different voltage ...

Electric locomotive is a kind of high power rectifier load, and its load characteristics will have a significant impact to safe, stable and economic operation of power system. This paper mainly analyses load characteristics of harmonic and reactive power for electric locomotive. Simulation model of electric locomotive is set up based on time trigger; it is so better conform to the dynamic chara...

IMPORTANCE Myomectomy, the excision of uterine leiomyoma, is now commonly performed via minimally invasive surgery. Electric power morcellation, or fragmentation of the leiomyoma with a mechanical device, may be used to facilitate extraction of the leiomyoma. OBJECTIVE To analyze the prevalence of underlying cancer and precancerous changes in women who underwent myomectomy with and without el...

Majority of the million plus cities in India are facing serious problems of traffic congestion and pollution due to the unprecedented and rapid pace of urbanization in last decade. City planners are providing solution to these twin problems by developing Mass Rapid Transit System including Metro and BRT in many Indian Metropolitan cities. The availability of transit network and pedestrian acces...

This paper introduces the reader to electric and magnetic fields, particularly those fields produced by electric power systems and other sources using frequencies in the power-frequency range. Electric fields are produced by electric charges; a magnetic field also is produced if these charges are in motion. Electric fields exert forces on other charges; if in motion, these charges will experien...

Travel reliability is the most essential determinant for operating transit system and improving its service level. In this study, an optimization model electric route network design problem proposed, under precondition that locations of charging depots are predetermined. Objectives to pursue maximum travel meanwhile control total cost within a certain range. Constraints about bus operation also...
