Crowbar電阻器－－低電壓穿越技術(shù)
Crowbar電阻主要應(yīng)用于風(fēng)力發(fā)電逆變器的低電壓穿越技術(shù)中。它用在風(fēng)力發(fā)電機(jī)轉(zhuǎn)子側(cè)，用于旁路轉(zhuǎn)子側(cè)變流器。當(dāng)電網(wǎng)發(fā)生低電壓擾動(dòng)時(shí)，防止直流母線電壓過高和轉(zhuǎn)子電流過大。主要工作在故障狀態(tài)，阻尼定子磁鏈。Crowbar電阻能在瞬時(shí)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.
