The booming electronics itself carries an impact on power quality. Superconducting Magnetic Energy Storage (SMES) is proposed to enhance power quality in three-phase systems under various loads. This paper aimed to compensate the voltage sags under various faults in the grid systems. The SMES is selected as an energy storage unit to improve the capability of voltage sag compensation. Optimized ...

Currently bacterial lipases are of great demand because of potential industrial applications (Sirisha et al., 2010). Lipases find their applications in various industrial sectors like processing of fats and oils, detergents and degreasing formulations, food processing, chemical and pharmaceuticals, paper mills, etc (Rubin and Dennis, 1997a,b; Kazlauskas and Bornscheuer, 1998; Masse et al., 2001...

One of the most concerning disturbances affecting power quality are voltage sags. Their major source are short-circuits on the utility lines. Faults many kilometres from the disturbed process will generate a momentary voltage sag in the electrical environment to the end user. A reduction of the short-circuit current magnitude may lead to a substantial power quality improvement because the major...

The “Power Quality” term is widely used in recent years in power system field. Voltage sags is one of the power quality issue, which is also known as dips, are important to industrial reliability. This paper presents a power world simulation approach to find the voltage sag magnitudes in power system network. In this paper, investigations have been conducted on a sample distribution system mode...

this paper presents a control strategy for fuel cell/energy storage power generation system during voltage sag conditions. the hybrid dc power sources are connected to grid using power electronic converters include dc-dc converter and grid connected voltage source inverter. the power from hybrid power sources is controlled during voltage sag by designing of control strategy for dc-dc converter....

The harsh and hostile internal environment of semi-autogenous (SAG) mills renders real-time monitoring some critical variables practically unmeasured. Typically, feed size fractions are known to cause mill fluctuations impede the consistent processing behaviour ores. There is, therefore, need for continuous parameters optimal operation. In this paper, an acoustic-based sensing method is employe...

Voltage sags caused by the short-circuit faults in transmission and distribution lines have become one of the most important power quality problems facing industrial customers and utilities. Voltage sags are normally described by characteristics of both magnitude and duration, but phaseangle jump should be taken into account in identifying sag phenomena and finding their solutions. In this pape...
