摘　　要：介绍了利用串联制动电阻(SDBR)在故障过程中吸收恒速风电机组的过剩有功功率,并提升机端电压以提高恒速风电机组故障穿越能力的措施,针对典型风电场分别做了准静态分析和暂态仿真。结果表明,串联制动电阻能有效地提高恒速风电机组的故障穿越能力,且具有经济、可靠、易于维护等优点。A novel alternative technology that inserts series resistance into the generation circuit is proposed.The series dynamic braking resistor（SDBR） dissipates active power and boosts generator voltage when faults occur.A representative wind farm model was used to study the beneficial effect of SDBR through quasi-steady-state characterization and transient fault ride-through（FRT） stability simulations.Theoretical analysis and simulations show that SDBR can substantially improve the FRT performance of the FSWT and has the advantages of being economic,reliable,and easy to maintain.
