ABSTRACT:

The aim of the project work is to protect the distribution transformer or any other power transformer, burning due to the overload, over temperature and input high voltage. Normally most of the transformers are burning because of these three reasons; hence by incorporating this type of monitoring and control circuits, life of the transformer can be increased. In addition to the monitoring and control, information about these three parameters can be transmitted to the nearest electrical office where the maintenance staff of the electrical department can monitor the transformer continuously without going nearer to the transformer.

INTRODUCTION:

Nowadays, with the advancement of technology, particularly in the field of computers as well as micro-controllers, all the activities in our day to day living have become a part of information and we find computers and micro-controllers at each and every application. Thus, the trend is directing towards computer based project works.

CIRCUIT ANALYSIS

The detailed circuit description of the project work APPLICATION OF “SCADA” FOR DISTIBUTION TRANSFORMER PROTECTION” is explained in section wise. For better understanding the total circuit diagram is divided into various sections and each section explanation along with circuit diagram is provided in this chapter.

Model of a communication system:

The overall purpose of the communication system is to transfer information from one point to in space and time, called the source to another point, the user destination. As a rule, the message produced by a source is not electrical. Hence an input transducer is required for converting the message to a time varying electrical quantity called a message signal. At the destination point another transducer converts the electrical waveform to the appropriate message.

DESCRIPTION 89C51 Micro controller IC

The AT89C51 is a low-power, high-performance CMOS 8-bit microcomputer with 4K bytes of Flash programmable and erasable read only memory (PEROM). The device is manufactured using Atmel’s high-density nonvolatile memory technology and is compatible with the industry-standard MCS-51 instruction set and pin out. The on-chip Flash allows the program memory to be reprogrammed in-system or by a conventional nonvolatile memory programmer.

ADVANTAGES AND APPLICATIONS

Advantages:

  • Can avoid cable intervention.
  • Can avoid manual intervention.
  • Can send the data from one place to other place by minor modifications.
  • Can monitor the system and the signal from remote places through some modifications.

    Applications:

  • In substations.
  • In corporate and government power generation plants.
  • In supervisory and control applications.
  • In industrial monitoring stations.
  • Inside power plant ,on power plant.
  • Industrial establishment.
  • Railways.

    CONCLUSION

    This project titled “SCADA IMPLEMENTED OVER POWER TRANSFORMER WITH REMOTE MONITORING SYSTEM” is a simulation model, by using Microcontroller ATMEL 89C51.
