CE 3.1 Project InformationName of the project: Hybrid State Estimation Using Synchrophasor TechnologyLocation of the project: Charotar University of Science and Technology(CHARUSAT), Gujarat, IndiaProject Duration: Please FillOrganization: Charotar University of Science and TechnologyRole and Designation during the time: Student of Electrical EngineeringCE 3.2 Project BackgroundCE 3.2.1 Characteristics of the projectPower System State Estimation is the process of estimation of the state of voltageangle as well as magnitude of each and every bus in any particular power system based on themeasurement that had been carried out at fewer buses. In the previous days, the measurementdevices could only provide the quantity measurement magnitude. However, in today’s worldan extremely effective and efficient device of measurement known as the Phasormeasurement unit or PMU has been introduced. This unit can solely measure the voltagephasor of both angle and magnitude of any specific bus where it has been placed and also thecurrent phasors of all the connected lines are being utilized. CE 3.2.2 Objectives developed for the projectThere are various objectives in this project. They are as follows:To utilize the phasor measurement unitTo estimate the state of power system
CE 3.2.3 My area of workMy major area of work was to estimate the state of power system. In the beginning, Iwas not sure about my work area and had various doubts. However, my project manager andother team members helped me to understand the entire scope of the project and also tomanage my responsibilities and duties. My second area of work was to document the entireproject report. This was again one of the major works that was given to me. Moreover, I alsoassisted my project manager.

My first major responsibility wasto study the research of the project work. I read about the entire concept of synchrophasor forsuccessfully applying my electrical engineering skills and knowledge. Moreover, I evenestimated the state of power system for the project and was responsible for making the
project successful. My next responsibility was to assist my project manager. I even tookproper follow ups in the project and attended various workshops and trainings. During myassistance to my project manager, I learned and explored various new things and understoodthe entire scope of the project. CE 3.3 Distinctive ActivityCE 3.3.1 Comprehending the Theory of the projectSynchrophasors are time constrained and synchronized numbers, which solelyrepresent both phase angle and magnitude of sine waves. These sine waves are normallypresent in electricity and are synchronized for accuracy. These sine waves are alwaysmeasured by the higher speed monitors, known as Phasor Measurement Units or PMU inshort. These phasor measurement units are much faster than the Supervisory Control andData Acquisition or SCADA. The phasor measurements units are the devices that solelymeasure each and every electrical wave on any particular electricity grid by simply utilizingany common source of time for the purpose of synchronization. This synchronization of timeenables the synchronized real time measurements of several measurement points present onthe electricity grid. The outcome of this measurement is known as synchrophasor. This is themost significant and important device for measurement in the near future of a power system.The phasor measurement unit is any particular dedicated device and can be easilyincorporated within any protective relay or similar devices. The accuracy of the synchronization is much better than one micro second and theentire set of measurements do give a real-time snapshot of power system. As the positivesequence voltages in all the network buses comprise the state vector of any particular powersystem, it has become extremely easier that the problem of state estimation. This problem can
