Adaptive transient overvoltage control strategy for wind farm based on data‐driven method

IET Electric Power Applications
To achieve the transient overvoltage suppression of doubly fed induction generator (DFIG) terminals and the point of common coupling (PCC) in the wind farm (WF), an adaptive overvoltage control strategy based on data‐driven approach is proposed. Firstly,

Overvoltage Simulation Analysis and Suppression of Breaking in a 35 kV Shunt Reactor

Energies
When a 35 kV distribution network has the problem of insufficient reactive power, the input of a shunt reactor is a common compensation method. Vacuum circuit breakers are widely used in 35 kV distribution networks because of their superior arc ...

Langmuir probe measurements of double-layers in a pulsed discharge [PDF]

Langmuir probe measurements were carried out which confirm the occurrence of double-layers in an argon positive column. Pulsing the discharge current permitted probe measurements to be performed in the presence of the double-layer. Supplementary evidence,

Transient AC Overvoltage Suppression Orientated Reactive Power Control of the Wind Turbine in the LCC-HVDC Sending Grid

CES Transactions on Electrical Machines and Systems
High-voltage direct current (HVDC) transmission is a crucial way to solve the reverse distribution of clean energy and loads. The line commutated converter-based HVDC (LCC-HVDC) has become a vital structure for HVDC due to its high technological maturity

Reactive power sensitivity-based novel overvoltage suppression strategy for parallel VSC-and-LCC-HVDC transmission system

International Journal of Electrical Power & Energy Systems
The rapid deployment of both line-commutated converter-based high-voltage direct current (LCC-HVDC) and voltage source converter-based high-voltage direct current (VSC-HVDC) does not only prolificate AC/DC grid coupling but also form new DC transmission ...

Research and application of UHV power transmission in China

High Voltage, 2018
The power demand increases rapidly in China; however, the areas of huge power demands are of long distance from most areas of abundant energy resource in the country. Therefore, China put in great effort to develop

Properties of HxTaS2 [PDF]

, 1975
The preparation of Hx TaS2 (0 \u3c x \u3c 0.87) is described. The compounds are only marginally stable at room temperature, slowly evolving H2S and H2 (and possibly Hp in air). Magnetic susceptibility data show that a low temperature transformation in 2H
