When the system employ the PC based stand alone controller then the positioning of the table results possible with the soft CNC, motion control program, and PLC for I/O control of the system. The controller in this application is Programmable Multi Axis Controller (PMAC).

It is a controller with high performance servo motion which is capable of commanding up to 8 axes of motion with a high level of sophistication. Motorola’s DSP 56001 is the CPU for PMAC to handle all the calculations for 8 axes.

There are four hardware versions of PMAC. They are the PMAC-PC, the PMAC-Lite, the PMAC-VME, and the PMAC-STD. It  is  to  note  that  PMAC  is  a full  computer  and capable  of  standalone  operation  with  its  own  right and stored  programs.

The abbreviation of CNC is Computer(ized) Numerical(ly) Control(led) which implies computer control of machine tools for the purpose of (repeatedly).

Numerical control or numerically controlled (NC) machine tools are machines automatically operated by commands which are received by their processing units.

Advantages include Smaller outside dimensions and large torque, Good operating efficiency, Good controllability, and Cheap.

Conclusion:

This project is aimed to demonstrate the feasibility of integrating the DC servomotor to the clamping mechanism and controlling its position through Programmable Multi Axis Controller called PMAC with Dc servo drive.

Powerline Voice And Data Communication For Device Operation offers an alternative means of communication. This project report provides an efficient means of communication over the existing electrical wiring as a communications medium. Power of communication, communicate using existing power lines. The main advantage of this type of communication is the existing infrastructure, which simplifies implementation General introduction to the power line communication, the understanding of some basic measurements of the properties to the behavior of the power line as a communication channel.

Every household would be connected at any time and services being provided at real-time. Using the power-line as a communication medium could also be a cost-effective way compared to other systems because it uses an existing infrastructure, wires exists to every household connected to the power-line network.

This system can be used in Nuclear Power Stations or Power Grid Stations, which are very hazardous for human beings to work in and needs heavy data transmission between the points. The present data signal transmission system can be further modified to send mixed signals such as graphics, video & audio signals over the power line. PLC technology is used to provide broad band internet over ordinary power lines. The system can be further modified to get the current status & execution of command of the load by audible beep. The above mentioned developments can be used in many public sector offices such as Railway enquiries, Bus Reservation Counter or in Electricity or Power Line Carrier Communication enquiry centers. Replacing the micro-controller with computer, one can make the system fully automatic and smarter one. The system can be more secured and comfortable with computer based control unit.

Fully Automated Burner Management System Using Plc The purpose of the protective relays and protective relaying systems is to operate the correct circuit breakers so as to disconnect only the faulty equipment from the system as quickly as possible thus minimizing the trouble and damage caused by faults when they do occur. Relays have revolutionized protection control metering and communication in power systems. Relay co-ordination will help to isolate the faulty region in the power system so that the fault at a particular region will not affect the other region in the system. Relay co-ordination can be done by selecting proper PSM and tsm of the relay and co-ordination can be checked graphically. Relay coordination in a power system will help to prevent the great loss and hazards caused due to the faulty conditions. Relays are also used to protect the transformer and motors also. Calibration of such relays are also done and also checked whether the relays are co-ordinate in each plant in FACT.

In a power system consisting of generators, transformers and distribution circuits, it is inevitable that sooner or later some failure will occur somewhere in the system. When a failure occurs on any part of the system, it must be quickly detected and disconnected from the system. There are two principle reasons for it. Firstly, if the fault is not cleared quickly, it may cause unnecessary interruption of service to the customers. Secondly, rapid disconnection of faulted apparatus limits the amount of damage to it and prevents the effects of fault from spreading into the system.

Conclusion:

The detection of a fault and disconnection of a faulty section or apparatus can be achieved by using fuses or relays in conjunction with circuit breakers. A fuse performs both detection and interruption functions automatically but its use is limited for the protection of low-voltage circuits only. For high voltages (say above 3.3kv), relays and circuit breakers are employed to serve the desired function of automatic protective gear. The relays detect the fault and supply information to the circuit breaker which performs the function of circuit interruption.

Project Report On Uninterruptable Power Supply (UPS) have become an indispensable element of many data processing installations (EDP), from desktop PC’s to mainframe computer systems. UPS systems provide a measure of insurance and security for the user who is concerned about data loss and hardware failures caused by power disturbances. The measure of insurance needed is proportional to the financial impact of the downtime caused by such an incident.

More recently, the introduction of computer based control systems in manufacturing and process control applications has prompted the need for UPS system in industrial facilities as well. Typical applications range from distributed PLC based controls to complete Distributed Control Systems (DCS) with power requirements ranging from 3 to 50 KVA. In addition to new plant construction, many older plants are upgrading both pneumatic and single loop control systems to distributed control, primarily to improve operating efficiency. Fundamental philosophical differences in system architecture indicate that industrial computer applications require different design parameters than their data processing counterparts and while UPS’s in commercial applications have largely become commodity items, industrial UPS systems remain an engineered product.

Project Report On Uninterruptable Power Supply (UPS) Conclusion:

In conclusion, there are many things to consider when specifying a UPS for industrial applications, only a few of which have been covered here. We’ve learned that industrial UPS systems generally have a high initial cost than their computer room counterparts. They are also more reliable and will be serviceable for the life of the plant. A cost justification based on the 15 to 20 year plant design life will show the cost of ownership for the industrial unit to be considerably lower. If you factor in the possibility of one incident traceable to the UPS that causes plant down time it becomes a foregone conclusion that spending a little more on the front end can save a substantial amount of money in the long run.
