Acrel-2000/3000 Supervisory Control and Data Acquisition

1 Real-time monitoring of distribution systems

The system has friendly man-machine interface,it can visually display running state of distribution line by form of primary wiring diagram and can constantly monitor voltage,current,power factor,electrical energy and other electrical parameters,and it can dynamically monitor switch status of circuit breakers,isolated switches,earth knife switches,and signals as related faults,alarm and so on.

2. Detailed electrical parameter query
In the power distribution map, when the mouse moves to the vicinity of each loop, the mouse pointer becomes a hand shape, and the mouse clicks to view the detailed electrical parameters of the loop, including three-phase current, three-phase voltage, three-phase total active power, and total Reactive power, total power factor, positive active energy, and can view 24-hour phase current trend curve and 24-hour voltage trend curve.

3.Running report
The system has the function of constant electrical parameters and historical electrical parameters storage and management,all real-time data collected, sequence event records, etc. can be saved to the database. In the query interface, the parameters that need to be queried, the specified time, or the logged data of the latest update can be customized, and displayed in a report manner. Users can customize the running daily and monthly reports according to their needs, support exporting Excel format files, and export PDF files according to user requirements.

4.Transformer operation monitoring
The system can provide real-time online monitoring for the running state of primary inlet,main voltage transformer,main load outlet.And it can display running tendency of current,voltage transformer running temperature,required active demand,active power,apparent power,voltage transformer load and other parameters.It can analyse load efficiency and consumption of voltage
transformer, thus it can enable the maintainers to know the running level and electricity demand and it can finally ensure the electrical safety and reliability.

5 Real-time alarm
The system has a real-time alarm function. The system can perform remote signal displacement, protection action, accident trip, and voltage, current, power, power factor violation and other events on the distribution circuit breaker, isolation switch, grounding knife, and combined action. Real-time monitoring and alerting based on event level. The real-time alarm window pops up automatically when the system alarms, and a sound or voice reminder is issued.

 6. Historical event query
The system can store and manage remote event displacement, protection action,accident trip, and event records such as voltage, current, power, and power factor violation. It is convenient for users to trace historical events, alarms, and accidents.

7. Remote control,manual open and close
The system supports remote open and close operation on circuit breakers,isolated switches,earth knife switches and so on. The system has functions of strict code protection and operation permission management,the system can automatically form the operation record for remote operation of every time which including operators,operation dates,operation types and so on.

8.Energy Statistics Report
The system supports the integrity of the system with a rich report body. The system has the function of timed meter reading summary statistics. The user can freely query the power consumption status of each power distribution node in any time period since the normal operation of the system, that is, the statistical analysis report of the power consumption of the incoming line of the node and the power consumption of each branch circuit. This function makes the electricity use visible and transparent, and can analyze and trace the electricity when the power error is too large, and maintain the correctness of the measurement system.

9. User authority Management
Stability of the system for the protection of system security, set up user rights management capabilities. Unauthorized operations (such as power distribution loop name modification, etc.) can be prevented by user rights management. You can define login names, passwords, and operation rights for users of different levels to provide reliable security for system operation, maintenance , and management.

10. Communication status diagram
he system supports real-time monitoring of the communication status of each device in the access system, and can completely display the entire system network structure; the device communication status can be diagnosed online, and the faulty device or component and its fault location can be automatically displayed on the interface when a network abnormality occurs. Therefore, it is convenient for the operation and maintenance personnel to grasp the communication status of each device in the field in real time, and timely maintain the abnormal equipment to ensure the stable operation of the system.

11.Login interface
The system can customize the personalized system login interface according to user requirements, such as the image and logo used in the login interface. The related content needs to be provided by the user

12.Network applications based on B/S

The system provides function of web page publishing,thus the user can check real-time data,monitoring picture,and historical data by IE browser based on windows system. The view effect is the same as system picture seen on client’s human-machine interface.

13. Open system extensions
The system supports data forwarding of multiple standard protocols such as Modbus-RTU and Modbus/TCP, and supports the development and access of non-standard protocol protocols, enabling all intelligent devices to seamlessly connect into the system; supporting industrial OPC, ODBC and other interfaces and other The system (such as the BA system) exchanges data to
facilitate data sharing with third-party systems.
