A method for system design technology, the technical parameters including the diagnosis system through the amounts and depends on the state variables to describe the characteristics: in the method, the equations describing the system, in which the state is the solution of equations; in the in the method, including the analysis of field measurement was first measured, in which the technology system in a predetermined accuracy measurement of the first to be measured, and the first to be measured depends on the amount of state; in the method, the accuracy in the system at a predetermined to measure depends on the state variables measured second. In the method, the sensitivity of second first sensitivity determining the first measured value and / or the second measured value; which in order to determine the first sensitivity value, measuring changes in the first measured the accuracy of determination of the effect of at least one of the selected parameters in the great degree on the second, and to determine the sensitivity value, measurement of the second measured the extent of at least one of the chosen parameters; in the method, dependent on the first and / or second such sensitivity values change the measuring field, so that one or more the first is the accuracy of the measurement is changed, and / or from the measurement field to remove one or more of the first to be measured, and / or one or more second measured added In the measurement field, the altered measuring field is used to design the technical system.

本专利技术涉及用于设计技术系统的方法和装置以及相应的计算机程序产品。在描述技术系统、例如发电站设备时,考虑诸如压力、质量流量等等各种参数。这些参数遵从一定的物理定律、例如质量或者能量守恒,这些定律可以通过方程组来表达。方程组的解是技术系统的状态量。从这些状态量中又可以为技术系统的运行计算相关的诊断量、例如发电站设备的效率。此外,技术系统的具体状态可以通过测量得出。所述测量的被测量可以直接再现状态量的值;但是也可以测量从状态量中导出的被测量。例如可以测量技术系统的温度,而该系统的状态量是焓和压力。为了从被测量中确定状态量,人们通常进行测量,并且寻找状态量,该状态量解出所述方程组,并且其导出的被测量尽可能地接近于通过测量确定的测量值。为此有标准化的方法(参见例如VDI规程2048)。可能出现下列问题,即由于方程组中极少量的方程或者极少量的测量点,单个状态量或者单个诊断量保持不确定。另外,由于测量误差,状态量或者诊断量具有大的不可靠性。因此必须决定,通过哪些测量可以提高某些状态量的准确度,或者才可以确定某些状态量。为此,通常动用有经验的工程师的建议,并且这些工程师的建议可以通过仿真程序进行检验。然而,为此需要费时的分析。因此本专利技术的任务在于,给出一种用于设计技术系统的方法,其中系统地测定,单个被测量的测量如何影响该技术系统的参数。该任务根据独立权利要求的特征来解决。本专利技术的改进方案在从属权利要求中阐明。本专利技术的方法用于设计技术系统,该技术系统通过包括状态量和取决于所述状态量的诊断量的参数来描述特征。在这种情况下,“设计”尤其被理解为分析和/或者 ...
