变桨距系统试验台测试技术与应用

Testing Technology and Application of Variable Pitch Control System Testing Platform

变桨系统测试平台建立的目的是模拟风场的运行环境,测试变桨系统的功能和性能,验证变桨系统的可靠性、快速性、准确性,同时为变桨系统的技术改进提供实验依据。为迎接全国范围内迅速展开的风电各系统多种形式的并网试验测试,文章给出了电动变桨系统平台测试方法。其中包含有故障穿越能力测试,能够有效应用于风力发电机组低电压穿越能力一致性评估工作。这对于确定详细的风机并网测试低穿认证具有重要的指导意义和实用价值,也有益于风电产业领域的提质增效。

With the purpose of simulating wind farm＇s environment, testing variable pitch system＇s function and performance, the electric variable pich control system testing platform is set. In order to meet all kinds of national grid connected tests, the platform testing method is also given. It contains the LVRT capability test, which can be use for the wind turbine LVRT capability conformity assessment.
