Research on Tuning Protection with Distributed Power Distribution Grid

Advanced Materials Research, 2014
Along with the gradually lack of the fossil fuels, people pay more and more attention to the use of renewable energy. Distributed power supply of a large number of interconnection affects the distribution network power flow direction and size a lot. Thus, the protection setting values of the distribution network line are not accurate, which lead to the

Power systems protection in an oil field distribution system

Conference Record 2009 IEEE Industrial & Commercial Power Systems Technical Conference, 2009
Power-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.

High-Frequency Fault Analysis-Based Pilot Protection Scheme for a Distribution Network With High Photovoltaic Penetration

IEEE Transactions on Smart Grid, 2023
Due to the influence of inverter control, the short-circuit current provided by distributed photovoltaics (PVs) exhibits new characteristics, such as a controlled amplitude and phase angle, resulting in the malfunction of the current protection and ...

Formal Verification of Protection Functions for Power Distribution Networks

IECON 2018 - 44th Annual Conference of the IEEE Industrial Electronics Society, 2018
This paper presents initial results on formal verification of protection functions in a smart power distribution grid. Informal properties of the smart grid were formalized in the language of LTL and formal verification is performed using NuSMV model checker on the closed-loop plant-control model which consists of IEC 61499-based control logic and an ...

Impact of distributed generation on distribution protection and power quality

2009 IEEE Power & Energy Society General Meeting, 2009
The 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.

Reverse Power Flow (RPF) Detection and Impact on Protection Coordination of Distribution Systems

IEEE transactions on industry applications, 2020
Due to the inclusion of distributed generation (DG) in modern power systems, there are certain changes in the distribution and transmission stage, either by impedance reflected by the lines, the increase of short-circuit currents, or the X/R relation ...

Fault protection on shipboard A-C power-distribution systems

Electrical Engineering, 1944
THE 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 ...

Fast Power-Up Active Link Protection in Autonomous Distributed Transmitter Power Control

2008 International Wireless Communications and Mobile Computing Conference, 2008
In this work, we propose an enhancement to the DPC/ALP (distributed power control with active link protection) algorithm that allows fast power ramp-up without compromising the ALP guarantee. The original DPC algorithm was first augmented with ALP to provide absolute performance guarantees.

Lightning protection of overhead power distribution lines

IEEJ Transactions on Electrical and Electronic Engineering, 2007
AbstractThere are two major protective methods against lightning outages on overhead distribution lines. One is by use of surge arresters and the other is by an overhead ground wire. Surge arresters have rather constant effect regardless of the type of lightning outage causes.
