Electric vehicles (EVs) are revolutionizing transportation, offering a cleaner and more sustainable alternative to traditional gasoline-powered cars. By eliminating tailpipe emissions, EVs significantly reduce air pollution in cities and contribute to a cleaner environment. Additionally, when charged with renewable energy sources like solar or wind, their environmental impact is further minimized. Electricity can be cheaper than gasoline, potentially reducing long-term running costs for EV owners. Additionally, EVs generally require less maintenance compared to gasoline vehicles due to fewer moving parts. When energy generation exceeds EV charging demands, the surplus energy is strategically directed to power streetlights. This reduces dependence on …

Pid Controller Design Of An Avr System, Soumya Pan Jun 2024

Pid Controller Design Of An Avr System, Soumya Pan

Manipal Journal of Science and Technology

Voltage control and reactive power management are two facets that enable the reliability of the transmission network. More reactive power demand causes a voltage drop at the generator terminal. Such reactive power demand may arise from some industries connected to the transmission line. Usually, this reactive power is of an inductive nature which causes the voltage drop. In this regard, automatic voltage regulation (AVR) is an important aspect that is responsible for the continuous adjustment of field excitation to maintain the generator terminal voltage constant. This is done by comparing the terminal voltage with a reference voltage and by changing …
