Gaoya dianqi, 2016 提出一种模块化多电平结构应用于动态电压补偿器的新技术。模块化多电平结构易扩展,便于实现,且具有公共直流母线,能够实现四象限运行。文中对模块化多电平动态电压补偿器的拓扑结构和工作特性进行介绍和理论分析。通过对几种补偿策略、子模块电容电压控制策略和MMC逆变单元调制策略的对比介绍,提出了适用于模块化多电平动态电压补偿器的同相补偿、子模块电容电压分层控制和载波移相PWM调制的控制策略。利用PSCAD软件搭建仿真模型,通过仿真分析,验证了模块化多电平动态电压补偿器控制策略的有效性和可行性。

Gaoya dianqi, 2015 在特高压输电工程（UHVDC）紧急停运（ESOF）或者闭锁（BLOCK）的过程中,换流站需根据不同的控制策略,投入旁通对以及闭合旁路开关。这对快速隔离故障或者保障其他阀组正常运行起着重要的作用。而错误地投入旁通对将对直流系统的紧急停运或闭锁产生不良影响。笔者就极闭锁时是否投入旁通对进行了对比,对不同策略下的实际波形进行了分析,说明在极闭锁时不投入旁通对更有利于直流系统的稳定运行。

A Systematic Scoping Review of Self‐Regulated Learning With AI in Language Education
International Journal of Applied Linguistics, EarlyView.ABSTRACT The rapid development of artificial intelligence (AI) technology has brought new opportunities for second/foreign language (L2) education while also raising concerns about the use of AI tools. This systematic scoping review provides a snapshot of the current state of research situated at the intersection of self‐regulated learning (SRL) and AI

Learner‐Focused Strategy Instruction From the Teachers’ and the Learners’ Perspective
International Journal of Applied Linguistics, EarlyView.ABSTRACT Numerous large‐scale quantitative studies have been conducted to yield a macro‐level picture of the effectiveness of strategy instruction. However, little is understood about learners' actual processing of strategy instruction and interaction with the teachers delivering it.

International Journal of Applied Linguistics, EarlyView.ABSTRACT This computational linguistic study analyzes 8743 Rednote posts to examine how sentiment, emotion, and content domain collectively shape social comparison dynamics on social media. We identify four key findings: (1) an emotional gradient, where upward comparison content exhibits the highest sentiment scores and downward comparison the lowest; (
