Abstract This paper proposes the use of a novel saturated amorphous alloy core-based fault current limiter (SAACFCL) to improve the LVRT capability of doubly-fed induction generator (DFIG) based wind energy systems, especially during voltage sag events. Compared to the traditional cores which are widely used in fault current limiter (FCL), amorphous alloy core possesses a very narrow B-H loop which indicates that the SAACFCL requires a smaller dc excitation current, and it will incur low core losses. Under normal conditions, this developed SAACFCL accomplishes low impedance and has a negligib...

Abstract The use of different control techniques has become very popular for controlling the performance of grid-connected photovoltaic (PV) systems. Although the proportional-integral (PI) control technique is very popular, there are some difficulties such as less stability, slow dynamic response, low reference tracking capability, and lower output power quality in solar PV applications. In this paper, a robust, fast, and dynamic proportional-integral resonance controller with a harmonic and lead compensator (PIR + HC + LC) is proposed to control the current of a 15-level neutral-pointclampe...

Power Quality’s SL series of uniterruptible power systems are designed to bridge the gap between high-priced UPSs and surge suppressors

The complete article can be found at AlabamaNewsCenter.com. By Savanah Kirchner Reid Buckner is a “detective” who locates problems for Alabama Power before they become critical and create power system failures and outages. He uses infrared thermography to locate equipment that is overheated. Buckner, a marketing technician in the Enhanced Power Quality group, also focuses on problem-solving and analysis, helping assure that power is within the proper specifications. “I was lucky enough to get the job in Power Quality and it’s turned out to be, I think, a good fit,” said Buckner, who...
