Wind Power
Wind power, at present, is one of the most mature and feasible renewable clean energy. It brings a great opportunity to human and nature harmonic development. Due to outdoor operational environment, lightning stroke and harmful surge becomes one of the most austere challenges to its operation. For wind power system, due to its special operating geography location, height, highly integrated by a large quantity of sensitive electronic, electrical components/ expensive cost, surge protection is strongly required. PTG provides comprehensive and effective solutions for it.
In accordance to IEC 62305 and IEC 61400-24, below should be considered when categorizing surge protection zones and selecting/installing the SPD:
1. Lightning protection zone (LPZ 0…3);
2. Relative SPD test waveshapes (8/20 μs or 10/350 μs);
3. Voltage protection level
4. Voltage and standard of power supply (230/400 V; 400/690 V; TT/TN system);
5. Harmonic wave interference
