Kagde Prof. Deshmukh B. T. (M.E. Student) (Assistant Professor) E & TC Department E & TC Department JNEC, Aurangabad, India JNEC, Aurangabad, India 1 2 sush_sanju@rediffmail.com BAPU_DESH@rediffmail.comABSTRACT World’s 90-95% industry works on power. Power is the heart of today’s industrial andcommercial revolution. It is generated conventionally as well as some natural resources areused in order to fulfil today’s power wants. The hydro power stations are the main resourcesof the electricity and power. Wind power station and solar power generation are some ofanother source. Bio gas power station may also be there. Still as for as the usage increases,the generation cannot be increased in that proportion. Hence there is always shortage ofelectricity. Hence we have to manage the usage of electricity in order to minimize theshortages. Hence the voltage, current and power factor are to be monitored. This will help tominimize the power loss due to poor power factor.Keywords- GSM, Power Factor, Microcontroller, ADC, ALPI. INTRODUCTION In day to day life how much electricity is important is very well known to all. Energyutilization gets increased but generation has some limits. In such conditions it is must to savethe energy in any way. Today the use of electricity is increased in a great extent butgeneration of energy is not in that proportion. So whatever the energy is there we have tosave it which was the primary need. Generally saving of energy depends on the “powerfactor”. So by improving power factor we can save energy. But how it can be done? So it isaccomplished using a circuit which is used to control and improve the power factor. Mainly Power factor describes the relationship between real and apparent power ofalternating current (AC) power systems. In an AC power system, current may flow into andback out of a load without delivering any energy. This reactive current gives rise to 324

Power factor is expressedas the ratio of the actual power to the apparent power. A power factor of 1.0, or “unity” isdesirable because it means that all the power delivered to the load is “real power” and there isno reactive current component to the load. As the reactive current and apparent powerincrease, power factor is expressed as a smaller decimal. Also the various parameters of thethree phase motoring and controlling is also important. But it is not possible to monitor theparameters continuously by human being. So full fill both the requirements the “The threephase data logging and fault detection using wireless technology” is developed.II. DEVELOPMENT OF SYSTEM Mainly the system consists of the two parts one is the master station part and other isthe slave station part. And the data transfer is done by using the master slave communicationprotocol. For the fast and efficient data transferring the serial data communication is used.This accomplished by using RS 485 and RS 232 serial interference IC’s. The data analysisand processing is done with the help of assembly language programming. For displaying the measured values of the three phase parameters the 7 segmentdisplay is used at the both stations. The type of the display is 16*2 character display which isable to show the values of the voltage, current, power factor energy units distributed at masterstation and consumed energy units at slave stations. According to the difference in the unitsof master and slave station the message was send to the authorised person.Figure 2.1: Block Diagram of 3- phase parameter Data Logging using wireless Technology- Master Station Above figure shows the system developed for the measurement of the parameters ofthe three phases that is voltage, current and power factor at master station .The system consistof the major functioning blocks which are used to perform the specific functions. Followingare the major blocks 325

The sensed voltage and current are then given to the signalconditioning block at which the main three operations takes place- filtering, amplifying andprovides the isolation between the previous and next stage of the system. The output of thesignal conditioning is in the analog form for further processing it is necessary to convert theanalog signal into digital one. To perform the same function analog to digital converter isused. The digital output is then processed by the microcontroller. At the microcontroller withthe help of the assembly language programming the data send to the specific authenticateperson on his/her mobile. So at the far distance also we can be able to monitor the parametersof the three phases. It also possible to detect the electricity theft using the same system. The slave station system is also same as per the master station so the same workingwill be taken place at the master station also. Following figure shows the slave station blockdiagram. For the data transferring from slave to master RS 485 ModBus Communication isused while at the Master station for the communication RS 232 is used.

It controls the flow ofdata from the transducer level to the wireless communication module. The complete BaseUnit Flow chart at master and slave station is as follows: 326
