Wind Power Doubly-Fed System

Pain Points in the Application Scenario

The grid contactor is the main control device for 75–80% of the power output control of wind turbine units, which requires high capacity and strong overload resistance. Conventional rear wiring takes up excessive space, resulting in low space efficiency.

Value of the Solution

The NDW3-40S circuit breaker is used together with the NDC1-2100 to achieve grid-side protection and grid-connection control. The NDW3-40HU circuit breaker is used together with the NDC1-2100HU to enhance voltage capability and reduce system costs. VPH750-25/3P and VPH888-12.5/3P+1P(T1+T2) SPD surge protectors realizes professional surge and lightning protection, effectively mitigating the impact of grid transients and lightning surges on core devices, and reinforcing the system's overall safety and reliable operation.
