摘要:
针对基于旁路电阻Crowbar装置的双馈风电系统故障穿越技术的一系列问题:Crowbar装置短接转子,无功功率消耗过多;Crowbar电阻产生高压威胁直流母线电容的安全;母线电容的过储能难以释放并威胁变频器的安全运行,而采用一种新型故障穿越技术。该技术采用双PWM变频器线路暂态优化控制,实现逆变器并联无环流运行。暂态优化控制包含双PWM变频器线路重构、Crowbar装置、无功电流给定和无功电流优先原则4个部分。通过与基于Crowbar装置的故障穿越技术对比仿真,验证新型故障穿越技术能够提高系统无功补偿能力、支持公共连接点电压、及时释放母线电容过储能以及保护变频器安全运行。新型故障穿越技术的设计参考德国E.ON公司电网标准,对我国今后制定并完善风力发电并网标准有着现实意义。
Abstract:
A bypass resistor-set known as crowbar utilized for fault ride-through(FRT) technology for wind power doubly-fed induction generator(DFIG) has a series of disadvantages: Rotor circuit shorted by crowbar consumes a large amount of reactive power;DC link capacitor may be exposed to an over-voltage by crowbar resistance;excessive energy stored in DC link capacitor is difficult to relieve and may threaten the safe operation of converter.To solve above disadvantages conventional crowbar technology caused,a novel...
