摘要
利用正弦拟合理论可以较精确地计算呈正弦分布数据的真实偏差值和偏差方位。对该理论的处理技术及计算机运用程序进行了简要介绍。结合金安桥机组安装实际,将该理论运用到金安桥水电站机组安装调整中,有效地提高了机组安装调整质量。
The true deviation and deviation direction of sinusoidal-distributed engineering data can be accurately calculated by the sine fitting theory. The theoretical extension and relating computer program were introduced herein. In the installation of generating unit of Jin＇anqiao hydropower Station, this theory was applied to calculate the installation deviation which be regarded as the adjustment basis. The practice shows that the installation quality is effectively improved.
