Optimal dispatch system solution for water conservancy pumping station

1. Program overview

Modern large-scale water conservancy pumping stations are responsible for various tasks such as irrigation, drainage, water supply for shipping, and urban water supply. The use of integrated automation systems can integrate control, operation and management, greatly improving the efficiency of the pumping station. Therefore, the use of a good comprehensive automation system is an inevitable choice for the construction of modern large-scale pumping stations.

In response to the current situation and needs of modern large-scale water conservancy pumping stations, Beijing Yakong Technology Development Co., Ltd., combined with years of actual project experience and advanced mathematical algorithms, has developed a mature water conservancy pumping station optimization scheduling system, and this system is already in China Successfully applied in several representative water conservancy pumping stations.

2. Project highlights

Practice has proved that this system has been applied in large-scale water conservancy pumping stations, showing the advantages of optimized dispatch, energy saving, consumption reduction, balanced utilization of equipment, and water supply tracking.

Optimized scheduling-According to the water consumption forecast, water delivery plan, combined with water regime and weather information, an optimized scheduling plan with fewer starts and stops, and the smallest flow rate fluctuations, is formulated, and the equipment is controlled through the secondary monitoring center.
Energy saving and consumption reduction-on the premise of meeting the water delivery volume, make economically operating equipment operation commands, including equipment settings to ensure the safe and stable operation of the entire water delivery system, minimize the entire system’s water abandonment and minimize energy consumption; In the actual case, for the full fixed speed pump station without the support of the variable frequency speed regulation system, a certain degree of energy saving effect was achieved by reasonably selecting the start and stop status of the unit. The calculated data showed that the energy saving rate can reach about 10%.
Equilibrium utilization of equipment—equal use of equipment and operation of equipment in the best curve state can not only improve equipment efficiency, but also extend equipment life.
Abundant audio-visual display methods-track and analyze the process and achievement of water supply through abundant audio-visual display methods.
Accident analysis and handling-set up a unified standard event classification model, and a linkage handling plan library formed based on scheduling experience. When the response time is particularly urgent, the centralized control center can directly operate the relevant equipment through the equipment operation authority.

Three, system architecture

The optimal dispatching system for water conservancy pumping stations consists of four levels:
