چکیده
Abstract When lightning intrudes into the over-voltage in 500 kV substation, wave will be introduced substation along line, which seriously affect insulation level of equipment. In this paper, firstly, working principle, characteristics, and current simulation ZnO arrester are described. Then, electromagnetic transient program (EMTP-ATP) used a GIS carried out research to over-voltage, specifically studied protection effect metal oxide arrester, compared under different locations operation mode, calculated 500kV Substation single 500kV. The influence positions arresters on magnitude equipment is also

Study on Lightning Intruding Overvoltage in Yantan Extension Substation
500kV substation is especially important to the grid of our country, once it encounters lightning damage, the safety and reliability of the whole power system will be directly affected. As lightning intruding waves will cause overvoltage on electric equipments by intruding from the transmission line or straightly stroking the substation, which seriously influences the insulation level of equipm...
متن کاملLightning Protection of Ehv Substations in Iran
Extra high voltage (EHV) substations are extremely vulnerable to the hazard of lightning strokes therefore, the shielding of these substations with a highly reliable protective scheme (shield wires) is an essential undertaking. In this paper an attempt is made to clarify the design procedure for shielding EHV substations against lightning with special reference to Iran.
متن کاملStudies on an Electromagnetic Transient Model of Offshore Wind Turbines and Lightning Transient Overvoltage Considering Lightning Channel Wave Impedance
In recent years, with the rapid development of offshore wind turbines (WTs), the problem of lightning strikes has become more and more prominent. In order to reduce the failure rate caused by the transient overvoltage of lightning struck offshore WTs, the influencing factors and the response rules of transient overvoltage are analyzed. In this paper, a new integrated electromagnetic transient m...

This paper describes methodology for the computation of the electromagnetic transients in the high voltage substations, taking into account transients on the substation grounding system. Simulation technology is based on the system decomposition. Interconnections between different subsystems are done in each time step using Thevenin equivalents. Frequency dependent impedance of grounding conduc...
متن کاملMitigation of Transient Overvoltages Generated Due to Switching Operations and Lightning in Gas-insulated Substation (GIS) Without Extra Limiter
Gas-insulated substations (GIS) have different specifications in proportion to air-insulated substations. Transformer failures related to lightning and switching are often reported in the gas insulated substation (GIS). This problem is the voltage magnifications due to reflections of switching and lightning surges at various junctions within the GIS. thereby overvoltages in GIS are more importa...
