Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
The terms "comprises" and "comprising," and any variations thereof, in the present description and claims and drawings are intended to cover a non-exclusive inclusion, such as a list of steps or elements.
The technical solution of the present invention is further described in detail with reference to the accompanying drawings and embodiments.
As shown in figure 1, all processes of a hydraulic power plant are combed, relatively important start-up and shut-down processes are selected, and all nodes of the processes are combed.
And selecting a proper node in the process, wherein the selection of the node can be selected by a hydropower plant operator according to the actual situation and is given to a selected interface.
After the process node is selected, the process variable to be monitored at the node is selected, and the basis of the selected variable can be determined by an operator according to the field condition.
After the variable is selected, the value of the variable at a certain node needs to be determined, that is, a white list is established, the value needs to be determined by an operator, and the values are not necessarily the same at different nodes of the same variable, as shown in fig. 2.
