The digital twin Xijiang Water Conservancy project, which Zhongcong technology participated in the construction, was successfully selected as the digital twin watershed construction pilot project of the Ministry of Water Resources. The project applied GCS-G5 series of high-reliability PLC products, comprehensive monitoring software SCADA and industrial control safety equipment independently developed by Zhongcong technology. Unified scheduling, remote control and intelligent perception of the equipment of the power station in the river basin are carried out to realize scientific scheduling of water conservancy projects and help build the intelligent water conservancy system of Xijiang River.

“Super project” heavy construction

Jiangxi Xiajiang Water Conservancy Project is located in the upper gorge of Baqiu Town, Xiajiang County, middle reaches of Ganjiang River. It is a large-scale water conservancy project which mainly uses flood control, power generation, shipping and irrigation. The project is one of the 172 major water conservancy projects in the country, and it is also the largest water conservancy project invested in Jiangxi Province so far.

Twelve power stations are distributed along the Ganjiang River basin. The stations in Xiajiang Reservoir area are remote, the distance between the stations is far, the automation degree of on-site equipment is low, and unified and accurate control cannot be achieved. The remote joint adjustment road is time-consuming and low efficiency, and the digital upgrading of water conservancy projects is imminent.

At the beginning of the construction of the project, in order to fully ensure the smooth landing of the project, the central control technology continues to tap the needs of users, repeatedly upgrade and improve the technical plan, after sufficient research and analysis, Jiangxi Province water injection river information finally determined the choice of central control technology, independent controllable, safe and reliable PLC products, comprehensive monitoring software SCADA and industrial control safety equipment.

“Hardcore products” come in turns

In this project, PLC products are mainly used in the control system of each power station, responsible for collecting equipment data in 12 power stations, designing redundant industrial Ethernet (A/B network) in the station, all industrial control systems are connected, communication between stations is realized through local telecommunication lines, and centralized connection to the Internet of Things platform. The site control system replaces the unified brand model and configuration template, reducing the skill requirements for maintenance personnel and saving maintenance costs.

On the basis of the automation of the control system, the integrated monitoring software SCADA is used to realize the configuration management at the center level to achieve the control at the center level, regional level and station level. At the same time, the system is configured with three-dimensional configuration screen, liquid level, pump operating temperature, voltage, current, power, energy consumption, gate opening feedback, equipment status and other data are presented in three-dimensional, clear and intuitive, which is convenient for unified and accurate scheduling.

PLC products and comprehensive monitoring software SCADA combine the operation and maintenance of hydraulic buildings, inspection and inspection, maintenance and other business management with the digital Xiajiang water conservancy hub, forming a complete automatic chemical operation and maintenance service capability, and realizing the real-time monitoring and intelligent operation and maintenance of pumping stations, gates, power stations and other working conditions. The visual simulation and real-time evaluation of various business key links, processes and parameters make the business system move from list-based to immersive, provide quantitative and visual decision support for business evaluation, and truly achieve the “unmanned duty” of the power station.

Nowadays, the automatic control system has been widely used in the construction of water conservancy projects. In the construction project of the digital Xiajiang control system of Xiajiang water conservancy project in Jiangxi Province, the central control technology has handed in a satisfactory answer sheet for the user. In the future, Zhongcontrol technology will continue to maintain the “spirit of ingenuity”, constantly upgrade products, “elaborate” programs, improve the service system, and press the acceleration key for the digitalization and automation development in the field of water conservancy engineering construction.
