To benefit from better wind conditions, wind turbines are often placed in exposed areas. However, they are more likely to be struck directly by lightning than traditional installations due to their exposed location and height. These events caused by lightning strikes can damage sensitive electrical equipment within the wind turbine system. Wind generators are equipment particularly exposed to the risks of lightning and transitory over-voltages: due to their height and to their location on high or/and isolated sites, the possibility of direct lightning strikes is much higher than for traditional installations. Wind turbines are generally located in areas exposed to the best wind conditions, offshore wind turbines are often located in prominent places such as mountainous and offshore areas located on the coast, through the effect of location and height of the system, wind turbines have the highest estimated annual number of lightning strikes according to the location of the lightning system.
All types of lightning flashes generate electrical impulses (LEMP) on the cables Industry Email List connecting the equipment, and the damage is mostly caused by insufficient discharge to withstand the voltage level of the equipment components. LEMP is the main threat that leads to malfunction and failure for electrical and electronic systems, now the most effective measures to reduce the loss towards LEMP are using integrated SPD protection in a set of SPDs choose well. Surge protectors are special features intended to direct the extra power produced by voltage spikes away from the main wind turbine system components. LSP has designed a complete range of AC and Telecom-Data surge protectors for Wind turbine applications that comply with IEC 61400 and IEC 62305 standards. The importance of surge protection Turbines are at high risk of lightning strikes. Wind turbines are often located in open areas with excellent wind sources. For example, offshore wind power generation is located in land outcrops such as mountains, while offshore wind power generation is often located in areas with high ground lightning density near the coasts.
At the same time, the blades of wind turbines can attract and pull the conductors up and get excited with the conductors down in the electrostatic fields of the thunderstorms, which increases the possibility of lightning striking the blades. For this reason, the estimated annual average number of lightning strikes on wind turbines is much higher here than in other areas. High maintenance costs. A lightning strike on a wind turbine can cause blade ablation, failure of electrical and control systems, and other phenomena. There are many types of events. The yield loss caused by wind turbine maintenance and downtime is considerable. For an offshore wind turbine, the maintenance costs are higher, and the maintenance time is longer. As a result, there is a huge indirect loss through delay. The threat caused by electric shock is great. Compared with direct lightning strikes, the indirect effect of lightning strikes, namely light electromagnetic lightning (LEMP), is more dangerous to the electrical and control system of the wind turbine. The main reasons are as follows: the probability of lightning strikes on the turbine blades is high.
