Function
Configuration
　　XSJ-1800BZ pumping station automation system is suitable for large, medium and small irrigation, drainage pumping stations and industrial and town water supply pumping stations that are newly built, expanded or rebuilt. The system uses object-oriented visual configuration technology, combined with IEC61850 standard protocol and related technology based on the Internet of Things, to achieve data collection, centralized monitoring, automatic control, protection, information interaction, fault diagnosis and information management of the whole station equipment.
　　The pumping station automation system uses a layered distributed structure of the pumping station control layer and the local control layer. The control layer of the pumping station includes a computer monitoring system and a communication system. The local control layer mainly includes equipment such as a pump control unit, a gate control unit, a common control unit, and a substation control unit.
　　The system is designed in accordance with the requirements of the "unattended (less-attended)" pump station, which can meet the requirements of safety, reliability, efficiency, and ease of use of the pump station. Management.

　　lReal-time data acquisition
　　The system can collect real-time data such as inlet and outlet flow, water level, temperature, oil pressure, pump inlet and outlet water pressure, cooling water flow, blade angle and other data, as well as circuit breaker position, pump set operating conditions, blade position, travel switch position signal, speed Relay signals, etc.
 
　　lReal-time data processing
　　The system has functions of various types of data over-limit monitoring and alarm processing, remote signal monitoring and processing, operation data calculation and statistics.
　　① Relay protection
　　According to the "six unifications" of the State Grid and the design specifications of the China Southern Power Grid's relay protection, the protection of lines, main transformers, capacitors, motor units and other equipment and power systems in pumping stations is achieved.
　　② Operation and automation control
　　It mainly includes the opening and closing control of circuit breakers and knife gates, start-stop control of pump sets, emergency stop operation of pump sets, blade angle adjustment of pump sets, start-stop control of public equipment, start-stop control of gates, switching operations of capacitors, and transformer Functions such as tap adjustment, protection of remote settings, remote adjustment of settings, and release and release of pressure plates.
　　③ Incident alarm
　　Provide real-time alarm and historical query printing functions of events. The types of alarms include alarms, actions, operations, systems, telemetry out-of-limits, telesignal shifts, etc. Historical event query can be divided into query by time period, query by factory information, query by group information, query by type, or a combination of methods.
　　④ Report curve
　　It provides the function of querying and printing historical data in the form of reports and curves. There are daily reports, monthly reports, and annual reports. Each report is edited and edited by the report editor, which is flexible and convenient. The historical data of any telemetry point can be consulted in the form of curves.
　　⑤ Module Management
　　Mainly used for management protector, PLC and other intelligent communication modules. It has the following functions: view the type and name of each module; view, modify and print the settings of each module; view the telemetry and remote signal data of each module; issue commands such as time calibration and reset.
　　⑥ Data communication
　　The configuration of the communication module is related to the needs of the site. Generally, it includes the protector communication module, PLC communication module, dispatch communication module, reserved other system communication modules (such as water information monitoring system, fire alarm system, etc.) and other intelligent communication modules (such as temperature monitoring Detector, electricity meter, excitation, governor module, etc.). You can check the real-time communication status and data through the message viewing window.
　　⑦ System timing
　　The system has clock synchronization capability, which makes the system clock synchronized with the satellite clock.
　　⑧ Human-machine interface
　　It mainly includes the electrical main wiring diagram, stand-alone monitoring screen, measurement summary screen, system operation state diagram, geographic wiring diagram, motor control diagram, start-stop flowchart, pump unit, gate, auxiliary machine operating conditions and real-time status of semaphores, It provides manual setting and operation interface, and displays historical information and comparison information of tidal volume and water level gauge with curves, bar graphs and controls.
 
　　lauthority management
　　Provides editing and verification of operation passwords. All authority checks and verifications in this system are implemented through the authority management module.
 
　　lMain equipment online monitoring and fault diagnosis
　　Configurable equipment online monitoring and fault diagnosis system can realize the online monitoring and fault diagnosis function of the main equipment of the pump station, which can improve the equipment running integrity rate, reduce equipment downtime and reduce maintenance costs. Pump station online monitoring equipment includes switchgear, transformers, capacitors, motors and pumps, gate valves, etc.
