Power system state estimation is a process to find the bus voltage magnitudes and phase angles at every bus based on a given measurement set. The state estimation convergency is related to the sufficiency of the measurement set. Observability analysis actually tests this kind of problem and guarantees the state estimation accuracy. A new and useful algorithm is proposed and applied in this pape...

The paper presents a laboratory development for measurement, analysis, design, and simulation of typical electric and electronic circuits using modern computer hardware and software. It shows computer measurement and data acquisition system using National Instruments (NI) LabView and NI-ELVIS, and gives methodologies for theoretical analysis and design of electric and electronic circuits using ...

Rydberg atoms based quantum microwave measurement technology has significant advantages such as self-calibration, traceability, high sensitivity and stable uniformity of measurement. In this work, from the dimension traditional electromagnetic theory, an electric field local enhancement technique for measurements is developed to improve receiver. The theoretical basis method comes different mec...

Due to limitations of 0.618 pole method, the triangle method and the champ ground resistance tester method on grounding resistance measurement of transmission lines and towers under conditions of complex landscape in a mountainous area, it adopts a generalized three-electrode grounding resistance measurement method which arranges electrode flexibly in the grounding resistance measurement of tra...
