Pump station real-time online monitoring and energy efficiency management method and system

Abstract

The invention discloses a system based on unit operation state real-time online monitoring. Online monitoring, data collection, data analysis, data processing, fault diagnosis and energy efficiency management of various data of a pump station are mainly studied. Data of all obtained state parameters is monitored according to the state, a feature value reflecting the unit operation state is extracted, the unit breaking down is diagnosed according to the feature value, and therefore the fault reason, portion, type, character, serious degree and development trend are determined, and maintenance is guided. According to energy efficiency management, the real-time data of all the obtained state parameters is monitored according to the state, efficiency calculation, economic indicators calculation and scheduling plan optimizing comparison are comprehensively carried out in combination with economic factors and market price factors of pump station operation, and therefore target optimization of energy efficiency management setting is achieved.

Description

technical field [0001] The invention belongs to the field of pumping station monitoring, and in particular relates to a method and system for real-time online monitoring and energy efficiency management of a pumping station. Background technique [0002] With the improvement of fault diagnosis technology and the increasing popularity of computer applications, it is imperative to implement the organic combination of computer monitoring and fault diagnosis in pumping stations. Foreign developed countries (such as the United States, Europe, etc.) began to establish pump station diagnostic systems in the 1980s, and began to realize data online for remote monitoring in the 1990s, realizing the "unattended" management mode, through computer monitoring Realize the monitoring of the operating conditions of the pumping station and the centralized management of all pumping stations in the entire watershed.

AI Technical Summary

Problems solved by technology

[0003] Due to the complex working conditions of large water pump units, extensive vibration parts, and many influencing factors (including mechanical factors, hydraulic factors and electromagnetic excitation factors), the general fault diagnosis system cannot fully meet the actual requirements of the pumping station.

Although some fault diagnosis systems have been developed in some domestic fields, due to the characteristics of large-scale water pump units, these systems are not completely suitable for water pump units, and the fault diagnosis of large-scale pump station units is still blank

At present, the starting, running and stopping of water pump units in domestic small and medium-sized pumping stations are mostly completed by manual operation, and there are usually many people on duty in the station. This situation is not only labor-intensive, but also work efficiency is not high

Most of the large-scale pumping stations built in China in recent years have been equipped with computer data acquisition systems, but in general, computer control of the operation process cannot be realized.
