EMTP-RV Analysis of Lightning Surges on Wind Turbines
This paper is concerned with lightning surge propagation on wind turbines. As wind power generation undergoes rapid growth, lightning incidents involving wind turbines have come to be regarded as a serious problem. Nevertheless, no known studies exist yet in Portugal regarding lightning protection of wind turbines. Hence, we present a case study, based on a wind turbine with an interconnecting ...
متن کاملModeling, Control and Simulation of a Chain Link STATCOM in EMTP-RV
-This paper describes an alternative STATic synchronous COMpensator (STATCOM), by connecting a number of Gate Turn Off (GTO) thyristor converters in series on the ac side of the system. Each GTO converter forms one ‘link’ of a 1-phase, full-bridge Voltage-Source-Converter (VSC) and is referred to as a ‘Chain Link Converter’ (CLC). Each GTO of a CLS, is switched ‘ON/OFF’ only once per cycle of t...
متن کاملMathematical Model of Electric Arc Respecting Mayr Theory in Emtp-atp
The mathematical interpretation of an electric arc is practically very difficult by virtue of its extremely accidental character. But on the other side, the mathematical formulation course of the electric arc is possible with transfer to the area of the mathematical modeling for specific conditions. Limits of influences of the electric arc are possible to determine with using results from mathe...
متن کاملRealization of Distance Relay Algorithm using EMTP MODELS
Digital technology has advanced very significantly over the years both in terms of software tools and hardware available. It is now applied extensively in many area of electrical engineering including protective relaying in power systems. Digital relays have many advantages over the traditional analog relays. The digital relay is able to do what is difficult or impossible in the analog relays. ...
متن کاملModelling of Electrode-arc Coupling in Electric Arc Welding
Modelling of the arc in electric arc welding is significant to achieve a better process understanding, thus gain better weld quality and a more efficient production process. It requires knowing the conditions at the surfaces of the anode and cathode. These conditions are very difficult to set from measurements and should be calculated. This requires modelling the complex physics of the electrod...
