| 摘要: |
| 风电机组并网运行前，需要进行低电压穿越能力的测试，专门的电压跌落模拟装置必不可少。基于此，研究了一种风力发电用变压器型电压跌落装置，可以模拟不同类型的故障，实现不同深度的电压跌落，电压跌落持续时间可调。为保证电压跌落测试系统能安全可靠工作，设计了完备的故障保护系统。通过建模仿真与现场测试实验，该装置可以满足实际工程需求，为风电机组低电压穿越测试中电压跌落装置实现方案提供选择与参考。 |

| Abstract: |
| Low voltage ride-though test of wind power generation system is carried out before connected with grid, it is necessary to use special voltage sag simulated generator for this test. A transformer typed voltage sag generator special for wind power system is researched, different type faults and voltage sag deep can be simulated, voltage sag last time is also adjusted. In order to ensure safe and stable operation of voltage sag test system, complete breakdown protection schemes are designed. Simulation and spot test shows this voltage sag generator is satisfied with practical engineering application, which provides implementation scheme and reference of voltage sag generator for wind power generation system low voltage ride through test. |
