Abstract: An electromagnetic transient modeling method and system for a high-efficiency synchronous machine, and, a device. The method comprises: predicting, of a synchronous machine, a first rotor angular velocity, a first rotor angle, and a first current q component of and a first current d component of an armature current, establishing a first Norton circuit for simulating the synchronous machine, and solving at the same time a second Norton circuit after equivalent transformation and a network conductance matrix so as to obtain a three-phase voltage of a synchronous machine port; according to the three-phase voltage, obtaining a second current q component, a second current d component, a second rotor angular velocity and a second rotor angle; and by means of error-controlled iterative solving, determining an electromagnetic transient simulation calculation result of the synchronous machine.

Abstract: A saturation effect-based synchronous machine electromagnetic transient modeling method, system and device. In the method, by predicting a first rotor angular velocity, a first rotor angle, a first current q component, a first current d component, a first flux linkage turning point d component, a first flux linkage turning point q component and flux linkage turning data of a synchronous machine, analysis processing is performed to obtain a corresponding second current q component, second current d component, second rotor angular velocity, second rotor angle, stator flux linkage d component and stator flux linkage q component.

Abstract: A storage and organizing apparatus for microscopy specimens is disclosed that includes a base with a top surface upon which are a plurality of slidable attachment tongues. A plurality of storage trays, each having a slidable attachment groove on a bottom surface thereof, is adapted to slidably engage one of the slidable attachment tongues of the base. Each tray further includes a plurality of specimen receiving means so that a plurality of specimens may be retained thereby. The specimen receiving means are adapted for receiving either a block specimen of tissue embedded in a resin block, a semi-thin section specimen of tissue mounted to a glass slide, a grid-mounted thin section, or any combination of these one, two, or three types of specimens. A cover may be included to slidably engage and capture each tray, whereby specimens held within the tray are prevented from falling out of the tray if the tray is inverted or jarred.
