摘要
针对发电厂过程测量数据中的过失误差对数据校正准确性的影响,根据鲁棒估计原理提出了一种具有较强鲁棒性的数据校正方法,使数据校正在避免过程测量数据过失误差影响的同时得到准确的校正结果。实际应用结果表明,该方法可得到数据的准确校正值,并能够侦破过失误差的位置,对数据校正具有较好的鲁棒性和有效性。
Directing against the influence of man - made errors of measured data in the process of power plant upon the accuracy of data correction, a data correction method boasting stronger robustness has been put forward on the basis of robustness- evaluating principle,making the data correction to avoid the influence of man- made errors, at the same time, to obtain accurate correction results. The result of application in one power plant shows that the said method boasts better robustness and effectiveness in data correction,it can detect the location of man- made error,obtaining the accurate correction value.
