IMPROVING VOLTAGE SAG RIDE-THROUGH IN
HYBRID FUEL CELL / BATTERY DISTRIBUTED
GENERATION SYSTEMS
ABSTRACT
In this paper controller design for voltage sag ride-through in hybrid fuel
cell/energy storage distributed power generation system has been presented. As the
amount of fuel cell power generation and other Distributed Generation (DG) with
power electronic in the grid grows, it becomes unacceptable to disconnect generat-
ing units every time a disturbance occurs, as was common practice in he past.
Keep ....etc

voltage, usually caused by a fault in A voltage sag is a momentary decrease in the rms the utility transmission line or distribution system within customer facility.

It is a temporary voltage drop below 90% of the nominal voltage level. Voltage sags and momentary power interruptions are probably the most important power quality problems affecting industrial and large commercial customers.

This paper describes the causes of voltage sags, their impacts on equipment operations and possible solutions. This paper focuses on system faults ....etc

EFFECTS OF VOLTAGE SAGS, SWELL AND OTHER DISTURBANCES ON
ELECTRICAL EQUIPMENT AND THEIR ECONOMIC IMPLICATIONS



ABSTRACT

Poor power quality has come to stay in most parts of the
world. In most part of Africa, especially in Nigeria, it is
almost normal not to have good clean power free from
disturbances. If power equipment and loads could talk or
express feelings, I am sure they would have made a big
protest against the great injustices imposed on them. A
survey was carried out amongst 15 multi-nation ....etc

This article describes the Voltage swell and overvoltage compensation problems in a diode-bridge rectifier supported transformerless-coupled
dynamic voltage restorer (DVR). applying conventional in-phase or phase-invariant boosting method in case of condition of swell or overvoltage, may cause a a rapid rise in dc-link voltage which may ultimately lead to the damage of the storage capacitors and switching devices, and increase the switching loss. The minimum energy injection scheme is unable to solve these problems. Here, a novel unidirectio ....etc
