产品简述 (Product Profile)
Crowbar电阻器－－低电压穿越技术
Crowbar电阻主要应用于风力发电逆变器的低电压穿越技术中。它用在风力发电机转子侧，用于旁路转子侧变流器。当电网发生低电压扰动时，防止直流母线电压过高和转子电流过大。主要工作在故障状态，阻尼定子磁链。Crowbar电阻能在瞬时把巨大能量耗散掉。
Low voltage ride through technology
A Crowbar Resistor is applied to rotor side of wind turbine, installed in converter system. It can reduce DC-link and low voltage of power network problem. It is working under fault conditions. It could dispathch thousands of joules of energy in
a very short time.
