Issue of Different Control Purposes of Different Units

In the modern condition, a mind-boggling issue is that of different control purposes of different units which are conveyed over an extensive territory. There are diverse control directs which require toward be physically worked in the event of any crisis or amid typical working hours and controlling different control focuses in the meantime may not be humanly possible. Each control unit must be controlled and changed manually and every one of them is vital. There can be human mistake while working them, bringing about genuine misfortune in mechanical assembling, though in industry each and every misfortune increases exponentially. In addition, there are few controls that must be checked routinely keeping in mind the end goal to take after changes in the framework and their effect on item. To screen each modification that is being conveyed at different spots over the unit is relatively inconceivable, and if a framework is required where you need to look at various units in the meantime, some ongoing slacks take after your way. Observing of different control frameworks causes issues in efficiency of a unit or even the entire business.

Switchgear system is one of these critical systems.. Switchgears help to monitor and control different distant units. These systems can be found locally or at separations from primary units. In this way, observing and controlling them physically turns into a troublesome assignment.

Checking and controlling issues are not constrained to industries only. They can be found in machines and gear we use in our labs for innovative work purposes.

To beat these issues, there are two conceivable routes out. Initially way, that is by all accounts a less demanding arrangement however not a more brilliant one, is expanding human work. By expanding human power working in a unit can tackle this issue to some degree. Hardly any slacks can be discarded and various units can be controlled and observed. Yet, in the more extended run, this arrangement will cause a few issues. In industries, expanding human power implies expanding load on economy, which implies less benefit by the end. Second solution is to design a system that can monitor and control distant units at the same time.

We have five switchgear systems in our lab which are being controlled and checked independently So, in our case if we develop a centralized control for switchgear systems, we can overcome the problem of managing and monitoring five units. Moreover Implemented SCADA of Switch Gear Systems on LabVIEW has its own significance.

LabVIEW (Laboratory Virtual Instrument Engineering Workbench) is a software to design systems using visual programming from National Instruments. By executing SCADA of Switch Gear System on LabVIEW we are essentially investigating another approach to work overwhelming machines in industry utilizing the most exceptional programming LabVIEW.

There are four basic aims of this project:

• Designing circuit for automatic control of modes of switchgear systems
• Controlling switchgear systems by PLC
• Monitoring and Controlling switchgear systems by HMI
• Monitoring and Controlling switchgear systems by LabVIEW

In our project SCADA based control and fault detection of Switchgear systems has been actualized. Switchgear systems are as often as possible and fundamentally utilized as a part of overwhelming modern process, their control is spine for drives of various machines. Fault in any part of Switchgear system can cause enormous misfortune. So it is important to detect it before any significant harm. In our project all the three modes of Switchgear System are controlled utilizing PLC and Lab VIEW. Switchgear systems in lab were being controlled manually. They have control buttons for ON and OFF and change over switches for selecting modes. On and off activities have another control; control through PLC yet modes must be changed manually.

We designed a circuit to replace manual control of modes with programmed control. In programmed mode, entire system is worked by PLC. Omron PLC is utilized to send signs to switchgear systems for different operations in various modes.

Programming is done by using ladder logic in CX-programmer. PLC is also interfaced with HMI. SCADA is created by utilizing cx-designer, in which status of all the switchgear systems are shown at HMI which covers the checking part. Moreover, control buttons are there on HMI too to control the system HMI sends signals to PLC according to the operation, and PLC operates switchgear sysyems. HMI is the fundamental controlling and observing unit and it can control and screen every one of the units at the same time.

After executing SCADA on HMI we moved SCADA of Switchgear Systems on Lab VIEW. All programming is done on Front Panel and SCADA can be visualized on Block diagram. LabVIEW will send signals to CX-Programmer according to which PLC will be operated ultimately driving Switchgear Systems.

Conclusion

To overcome the problem of controlling and monitoring of distributed systems the best way is to implement their SCADA. In industries Switchgear Systems are of great importance, by implementing their SCADA industry can be revolutionized. Implementation of SCADA of Switch Gear Systems on LabVIEW explores a new way to drive heavy machines on advanced software on which real time data can be visualized and controlled.
