Энергетические режимы трехфазной трехпроводной цепи [PDF]

, 2013
Для трехфазной сети в точке подключения несимметричной нагрузки рассмотрены неуравновешенный и несбалансированный режимы потребления электроэнергии. Показано, что при синусоидальных процессах эти режимы определяют разные уравнения мощности.

Optimized Hierarchical Power Oscillations Control for Distributed Generation Under Unbalanced Conditions

, 2017
Control structures have critical influences on converter-interfaced distributed generations (DG) under unbalanced conditions. Most of previous works focus on suppressing active power oscillations and ripples of DC bus voltage.

A Smart Bio‐Battery Facilitates Diabetic Bone Defect Repair Via Inducing Macrophage Reprogramming and Synergistically Modulating Bone Remodeling Coupling

Advanced Functional Materials, EarlyView.
This research presents a novel implantable bio‐battery, GF‐OsG, tailored for diabetic bone repair. GF‐OsG generates microcurrents in high‐glucose conditions to enhance vascularization, shift macrophages to the M2 phenotype, and regulate immune responses.

Investigating and Simulating DGs to Improve Voltage Profile and Reducing Power Loss in Unbalanced Distribution Networks

Advances in Electrical and Electronic Engineering, 2014
Development of Distributed generations (DGs) has changed the nature of power networks from passive to active. In order to specify a proper model for DG units, function and connection style of DGs to the network (direct or indirect) must be clarified.
