中文摘要： 目前，我国已制定了并网型风电机组相关标准，初步形成了大型风电机组标准体系，完成了大型风电机组认证规范编制，提高大型风电机组的测试、评价、认证能力，但是风电行业的整机测试评估技术等公共平台建设起步晚。美国FLUKE、日本日置等著名仪器公司生产的电能质量测量仪器广泛应用到风电行业，测量评估风力发电机组闪变及谐波分析。但存在问题：一是以上仪器的闪变评估采用瞬时电压进行计算评估的，无法准确真实评估风力发电机组本身产生的闪变；二是标准GB/T 20320中电网阻抗相角要求四个固定角度观察评估，而这个也是无法直接测试评估。 我们要针对以上问题，研究瞬时电流进行计算的闪变算法及谐波分析算法，研发具有自主知识产权的风力发电机组电能质量测试系统，能够实现标准GB/T 20320的电能质量测量和评估方法，对提高我国风电机组整机测试技术，具有一定的研究意义和示范作用。

英文摘要： At present, the related standard of grid-connected wind turbine already set, the standard system of large scale wind turbine have initial formation, the certification specification preparation of large scale wind turbine has already completion, enhance the capacity of measurement evaluation and certification for big scale wind turbine. But the start in whole measurement estimate is backward. The power quality measurement instrument by FLUKE in American and HIOKI in Japan company made has been widely used in wind turbine industry, it measurement evaluation the flicker and harmonic analysis for wind turbine. But there has problem: first one the above instrument is use the instantaneous voltage to calculation the flicker, this is cannot get the accurate the result of wind turbine; second in the standard GB/T 20320 need four fixed angle to observe the power grid impedance phase angle, however those cannot direct measurement and evaluation. To solve above problems, we want study on the algorithm base on calculation the instantaneous current and harmonic analysis, development the system of wind turbine power quality measurement with self-owned intellectual property right, it can be achieved the standard GB/T 20320 for the methods of power measurement and evaluation, there has some meaning to improve technology of whole machine measurement, there have some study significance and demonstration effect.
