6 FAQs about [Wind power generation lightning rod overhead line]
What if lightning strikes a wind farm overhead line?
The overhead line in wind farm is vulnerable to lightning strikes at a high risk. The lightning surge would propagate along the line and damage the equipment in substation.
Do wind farm substations have a transient response under lightning strike?
The wind farm substation is divided into multi zones and the transient response at different nodes is obtained. It indicates that the characteristics and propagation for surge under lightning strike on overhead line are completely different from direct lightning strike on wind turbine receptor.
What are the characteristics of lightning transients for wind farm?
Characteristics of lightning transients for wind farm Consider a lightning strikes No. 3 transmission tower. The magnitude of lightning current is set to 100 kA; the front time and tail time are 2.6/50 μs, respectively. The transient responses are plotted in Fig. 14. Fig. 14. Transient response of wind farm under 100 kA 2.6/50 μs lightning strike.
What happens if lightning strikes a wind farm?
In addition to wind turbine, the lightning surge would also propagate into substation along the line and threaten the safety of power equipment. The transient response under lightning strike is plotted in Fig. 24, and the voltage rises at crucial nodes of wind farm are presented in Table 5.
Why do wind farm substations need a lightning converter?
The lightning surge also passes through the converter. As a kind of electronic device, it is sensitive and prone to damage under severe lightning condition. Furthermore, the arrangement of wind farm substation is also different from traditional substation. As a consequence, the transient response is changed.
How does wind turbine rotation affect Lightning?
The rotation has different effects on the lightning - attracting ability of wind turbine for short and long gaps. In the case of lightning strike on wind turbine, the heavy current would pass through the tower, the grounding system and finally dissipate into soil.
