Steel fiber is the most widely used type of fiber in concrete because of its advanced and
economical manufacturing facilities, reinforcing effect, and ability to cope with changing …

This paper proposes a short-term frequency-response scheme of a doubly-fed induction
generator (DFIG)-based wind turbine generator (WTG) for improving rotor speed recovery and …

Mask wearing is known as one of the most effective and convenient methods for preventing
the transmission of viruses. Accurately determining whether a person is wearing a mask …

The traditional traction power supply system has electric phase separation, which restricts the
train speed. At the same time, negative sequence, harmonic and reactive power problems …

To arrest the frequency nadir for a frequency event, the rapid release of kinetic energy stored
in a doubly fed induction generator (DFIG)–based wind farm during the initial stage of an …

A stepwise inertial control (SIC) scheme of a wind turbine generator (WTG) instantly increases
the power output to arrest the frequency drop when a disturbance occurs; however, the …

To address the issues of the mechanical stress of doubly-fed induction generator (DFIG) and
the service life of energy storage systems (ESSs) resulting from excessively and frequently …

The tree continuous co-phase power supply system of heavy-haul railways can minimize
the safety hazards caused by neutral sections in the line and improve the utilization rate of …

Nowadays, low water-to-cement (w/c) ratio has been put into widespread use in engineering
practice. However, low w/c ratio may give rise to high self-desiccation, which may lead to …

High strength concrete (HSC) containing silica fume (SF) is widely utilized in construction
practices, and its cracking resistance attracts considerable attentions. Previous studies mostly …
