摘要
以艾默生公司OVATION系统的分散控制系统流量补偿计算组态应用为实例,组态时首先要获取流量测量装置的流量计算书,依据实际流体特性,选择正确且经过论证的流量补偿公式进行组态,进而使用标准流量单位进行计算,然后对流量测量小信号进行合理的切除处理,以获取准确的流量计算数据,为机组安全稳定运行创造有利条件。
The application of DCS flow compensation calculation configuration of Emerson OVATION system was taken as practical example. The first step is to obtain the flow calculation sheet of the flow measuring devices. Then,according to practical fluid characteristics,the next step is to select the correct and verified flow compensation formula to form calculation configuration and to calculate using standard flow unit. Afterwards,the small flow measurement signals can be removed rationally for obtaining accurate flow calculation data. The application of the flow compensation calculation configuration can create favorable conditions for safe and stable operation of the unit.
