Abstract

The invention provides a pumping station operation information visualization method for energy efficiency evaluation, including determining the reference flow value and reference head value of the pumping station, obtaining the flow value, head value and efficiency value of the pumping station during operation, and sorting out the pumping station A record table composed of flow normalized value, head normalized value and efficiency value during the operation process, determine several operating characteristic points and their corresponding frequency values ​​and average efficiency values, restore the flow value and head value of the operating characteristic points and Perform steps such as visual drawing of the combination information of each operating feature point. Based on the statistical analysis of data, the present invention expresses the complex historical operation data of the pumping station into a number of representative operating characteristic points, and each operating characteristic point corresponds to statistical information such as frequency value and average efficiency value, and draws different positions, The solid circles of radius and color are used to distinguish different operating feature points, so as to complete the visualization of pumping station operating information, which has the advantages of being scientific, reasonable, intuitive and concise.

Description

technical field [0001] The invention belongs to the technical field of pumping stations, in particular to a visualization method for pumping station operation information used for energy efficiency evaluation. Background technique [0002] The pump is a general-purpose equipment with a wide range of uses, mainly used in the transportation and pressurization of various fluid media. Usually in industrial and agricultural production and residential life occasions, several pumps are connected in series and parallel to form a pumping station to work. Pumping stations consume a lot of energy during operation. According to relevant statistics, the annual power consumption of pumping stations in my country accounts for about one-fifth of the total power generation. Therefore, the energy consumption of the pumping station has been widely concerned by people. [0003] In order to realize the purpose of energy saving of the pumping station, the prerequisite work is to conduct statist...

Problems solved by technology

However, the operation process of the pumping station is often very complicated: on the one hand, the pumping station itself may be composed of multiple pumps connected in series and in parallel, and several pumps will be replaced during operation; on the other hand, the end objects served by the pumping station may also be time changes

Therefore, during the operation of the pump station, the performance curve of the pump station and the resistance curve of the pipe network where it is located are likely to be in a state of dynamic change, which brings a lot of trouble to the statistical analysis and expression of the pump station operation data, resulting in subsequent The Inconvenience of Energy Efficiency Assessment Work

[0004] The current known technical solutions often divide the flow value of the pumping station into different intervals, and then count the average power value in each flow interval, but this method loses the head information and does not take into account the running time of different flow intervals. Accounting for the proportional factor of the total running time of the pumping station, this method has limited guiding significance for energy efficiency assessment work, and it is also impossible to accurately evaluate the energy-saving effect of various possible subsequent energy-saving renovation schemes based on the statistical analysis results of this data
