摘　　要：根据IEC推荐闪变评价标准,设计了模拟闪变仪,针对传统模拟闪变仪产生的问题,利用双线性变换法,提出并构建数字闪变仪,具有比模拟闪变仪仿真精度高、速度快、采样数据少,在闪变测试低频段误差率更低等优点。仿真结果表明,数字闪变仪更能满足低频段风电闪变测试需要,有效改善风电闪变的测试。The analog flicker apparatus was designed, according to IEC recommended flicker evaluation stand- ard and flicker apparatus design program. Using the bilinear transformation method, the digital flicker meter was put forward. The simulation result shows the digital flicker meter, compared with analog flicker apparatus, has advantages of fast speed, high precision, less error rate at flicker test low frequency band. It can satisfy the low frequency band wind power flicker test needs, effectively improve the wind flicker testing.
