Power Systems: Generation, Transmission, and Distribution
UNIT 1
Power Systems: Generation, Transmission, Distribution
Generation (1-30kV), Transmission (115-800kV), Distribution (2.4-69kV), Consumers (120/240V).
Generated power = Consumed power.
Base demand: Needed all the time (100%).
Intermediate demand: Constant for a long time.
Peak demand: Changing all the time.
Hydro Power (1)
P = 9.8 * q * h
- P (kW)
- q (flow rate)
- h (water head)
V = A * d
Time (t) = V / q
Hydro Power (2)
- Base power: 100MW
- Peak power: 60MW
Thermal Power (1)
η = (1 – T2 / T1)
- η = efficiency
- T1
Woodcut and Intaglio Printmaking Techniques
Woodcut
Fiber and very smooth, often used pieces of wood are holly and boxwood, especially from Turkey. This wood is harder than that used in the “straight” technique and thus is carved with a chisel (usually a metal tool). By using chisels, fine lines appear in the resulting picture as a white line drawing. This is opposite to the black line drawing of the woodcut in a row and thus, pictorial engravings can be achieved in the woodcut. Another advantage is that there is no size limit: in the “straight”

Difference Between Combinational and Sequential Systems
Combinational systems are characterized by their outputs, which depend only on the value of their inputs. In sequential systems, the values of the outputs at any given time depend not only on the inputs but also on the state in which they are.
Multiplexer
A multiplexer is a circuit that allows the selection of which of several input data lines should appear on a single output line. Its main application is to send data through a single output
