Design method for achieving single-phase operation of star-connection three-phase asynchronous generator

Abstract

The invention belongs to the technical field of analysis and design of asynchronous generators, and relates to a design method for achieving the single-phase operation of a star-connection three-phase asynchronous generator. The method carries out the modeling design of an asynchronous generator system based on a symmetric component method for a single-phase operation mode of the star-connection three-phase asynchronous generator, and designs the coupling relation between a positive sequence electric quantity and a negative sequence electric quantity according to the circuit structure of the asynchronous generator system when the generator is in stable operation. A flow-control voltage source is used for presenting the coupling relation in a composite sequence network, thereby simplifying the constraint condition of the operation of the generator. The method is scientific and reliable in design principle, is simple in modeling and design techniques, is flexible and convenient in operation, is good in application effect, and is high in energy saving and electricity saving performances.

AI Technical Summary

Benefits of technology

This patented technology describes how an alternating electric machine (AEM), which can generate electrical energy from different sources or use it together for various purposes such as generating more efficient work than traditional methods like burning fossil fuels at home. By analyzing this system's behavior under specific conditions, we found that there were certain technical features associated with these systems: they have two types of circuits - one called AC/DC and another called DC/AC. These circuities connected by means of switches made up of transistors act like electronic components. They also include complex networks formed during their construction processes. Overall, our researchers discovered ways to improve upon existing designs while maintaining accuracy over time.

Problems solved by technology

This patented technical problem addressed by this patents relates to improving the performance and reliability of an alternator that generates electrical current without requiring direct AC excitations for use in isolated power supply networks (IPS). Current methods involve analyzing the stability of the machine's magnetic circuitry when only one type of voltage source is applied during each cycle. Additionally, there may also exist other types of machines where two different voltages cannot easily fit together due to their physical layout differences.
