This project report is coming under the category of MATLAB based projects. Many of the electrical project ideas which are purely electrical come around harmonics, disturbances, voltage sag etc. This electrical project involves a concept of dynamic voltage restoration by means of a standby device called Dynamic Voltage Restorer (DVR) in normal conditions..
EEE MATLAB project abstract:
An operational load of various amperes undergoes voltage sag or produces a spike voltage during its operation. Only the power quality determines the failure or success of operation in an equipment whereas power quality is the only parameter that states the condition of electrical tolerance of a load. The Dynamic Voltage Restorer(DVR) operates in standby mode in normal conditions whereas in case of disturbances variation in the output voltage occurs.
To maintain the supply voltage to the operational load within prescribed limits, the dynamic voltage restorer injects the differential voltage.For better understanding we provide certain circuit diagrams of boost transformer, DVR, dc charger etc with some derivations techniques.
The dynamic voltage restorer is a sensitive device which is used in power distribution networks and its smaller in size, lower in cost and faster in response towards many disturbances. As control technique is used, control system components such as PI controller and discrete pulse generator for screening Pulse Width Modulation(PWM) signals. Voltage sag occurs only when rms (root mean square) value of the voltage ranges between 10 and 90 percentage of nominal voltage for one half cycle to a minute.
The voltage sag occurs only during starting an electric motor/short circuit/overload conditions. Power systems and power electronics are the two branches of electrical engineering science used in these models of EEE projects. A MATLAB is a simulation software used to model and simulate the appropriate output waveforms of voltage in dynamic voltage restoration process.
