Embodiment Construction

[0044] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0045] In practice, due to the needs of pumping station management, flow sensors and pressure sensors are generally installed on the outflow main pipe of the pumping station, and water level sensors are installed in the suction well or in the clean water tank of the water plant. In addition, in the water pump, the water pump inverter , There are also relevant sensors on the control valve to record the operation switch status of the pump, the operation frequency of the pump motor, and the change of the opening of the control valve. These facilities record the operation status of the pump station, and form the daily operation history data of the pump station to be stored in the database. The present invention uses the daily operation historical state data of the pumping station to determine the characteristic curve of the water pump in the pumping...

Abstract

The invention discloses a method and a system for determining a characteristic curve of a water pump in a pump station, and belongs to the field of estimation and measurement of parameters of equipment of a water supply pipe network. The system comprises each pump station basic data database, a pump station historical operating state data database, a pump station water pump characteristic curve deterministic algorithm and a GUI interface, wherein each pump station basic data database and the pump station historical operating state data database are collocated in a pump station management information system and based on GIS or CAD; the pump station water pump characteristic curve deterministic algorithm comprises at least a GIS-based or CAD-based pump station hydraulic analysis model, a genetic algorithm-based optimal algorithm routine and a pump station water pump characteristic curve estimation algorithm; and the GUI interface is allocated at a client. In the method, the characteristic curve of each water pump in the pump station is determined according to the historical operating data of the pump station by using the pump station water pump characteristic curve deterministicalgorithm. Due to the adoption of the method and the system, the characteristic curve of the water pump can be determined by only collecting and using the historical daily operation data of the pump station and each pump in the pump station does not need to be specially tested, so the testing cost of the water pump is saved and the damage to the equipment of the pump station and the influence on the water consumers are reduced.

Description

technical field [0001] The invention belongs to the field of parameter estimation and measurement of water supply pipe network equipment, in particular to a method and system for determining characteristic curves of water pumps in pumping stations. Background technique [0002] In the water supply network modeling, it is necessary to accurately grasp the performance of the pumps in the pumping station. Practice has shown that the performance of the pumps in the actual pipe network system cannot be based on the theoretical characteristics of the pumps when they leave the factory. The main reasons are: 1. After the pumps leave the factory, there may be After cutting and transformation; 2. After the pump runs for a period of time, some hydraulic characteristics change. Therefore, the theoretical characteristic curve no longer has practical value in the pipe network model, and actual measurement is required. [0003] The traditional measurement technology of the characteristic ...
