摘要
文中给出了数据融合算法,并提出把数据融合方法应用于火电机组的在线性能计算中,使计算结果能更完善、准确地反映机组的运行状况。这种数据融合方法计算简便,可以反映传感器在空间或时间上的冗余或互补的信息,获得比有限个传感器的算术平均值更准确的测量结果,具有较高的可靠性,实际应用结果证实了该算法的准确性,可推广到其它具有正态分布特性测量结果的数据融合。
This paper presents a new data fusion method for on-line performance calculation of turbogenerator and gives the data fusion algorithm. The algorithm can make the performance calculation result reflect the turbogenerator抯 real status well and truly. The algorithm is simple and reliable. Compared with arithmetic means of finite sensors, it can obtain more exacter measuring result. The algorithm can also reflect redundancy or complementary information of multisensor in space or time. The actual application result shows that the algorithm is effective, and can be used in other measuring data fusion, which the measuring data belongs to normal distribution.
