Impact of distributed generation on distribution protection and power quality
2009 IEEE Power & Energy Society General Meeting, 2009The impact of distributed generation (DG) on voltage sags in a distribution network depends on the design of the protection system and the coordination between the different protective devices. DG changes the radial nature of distribution systems and affects the performance of the protection system.

Power systems protection in an oil field distribution system
Conference Record 2009 IEEE Industrial & Commercial Power Systems Technical Conference, 2009Power-system protection for oil-field distribution systems consists of protection for electrical submersible pump (ESP) installations and their upstream electrical circuits. In this paper, a comprehensive protective-device coordination and an arc-flash hazard analysis are conducted for a large oil-field distribution system.

Protection schemes for distribution lines in DC power grid
2015 IEEE Innovative Smart Grid Technologies - Asia (ISGT ASIA), 2015DC distribution network will be widely used in the future with more integration of distributed generation. However, development of DC distribution is hindered by lack of appropriate circuit protection technologies. Certain protection schemes are studied in this paper, and used to detect and isolate the fault on the distribution lines and bus-tie line ...

Fault protection on shipboard A-C power-distribution systems
Electrical Engineering, 1944THE growth in the use of electrically driven auxiliaries on shipboard has produced very large increases in the installed generating capacity. This fact together with the necessity for maintaining a high degree of reliability and continuity of service in shipboard powerdistribution systems has emphasized the importance of providing adequate fault ...

Distributed Generation: impact on Protections and Power Quality
IEEE Latin America Transactions, 2013The present energy crisis drives to carry to an extreme the use of all the available energy sources, which need to be connected in their closest point. Traditional electric systems are changing their characteristics. Power quality is one of the aspects modified by the presence of distributed generation (DG), specially respect to harmonics, flicker ...

Influence of harmonics on power distribution system protection
IEEE Transactions on Power Delivery, 1988The effects of nonsinusoidal voltages and currents on the performance of static underfrequency and overcurrent relays are experimentally studied. The tests were conducted in such a way that the frequency, amplitude and phase shift of individual harmonics could be adjusted in a controlled manner by using a waveform generator with a phase-locking circuit.

Impact of distributed generation on protection of power system
2017 International Conference on Innovative Mechanisms for Industry Applications (ICIMIA), 2017Day by day demand of Electricity is increasing so, in order to fulfill this demand we need to increase generation of power. Because of this increasing demand, non-renewable energy sources are on the verge of extinction so the solution is to use renewable energy sources. One such solution is to connect DG having renewable energy sources in power system.

Power distribution system equipment overvoltage protection
IEEE Transactions on Industry Applications, 1994Application of surge overvoltage protection devices in general is based upon rule of thumb without the benefit of understanding basic parameters, system components and configuration, and energy content of the surge. This may result in the selection of an inadequate device.

Power Management and Protection of Distribution Systems with Distributed Generations
2017Future electric distribution systems will deploy an increasing number of distributed generations (DG), with a large portion being renewable generations and some being fossil-fueled generations. There will be a rising number of microgrids that can operate in both grid-connected and off-grid mode.
