Study Notes
Energy Definition
- Energy is the ability to do work and comes in forms like heat, light, motion, electrical, chemical, and gravitational.
- Some energy resources are limited, others are unlimited.
- Limited resources should be used wisely.
- Problems associated with using large quantities of energy include:
- Depletion of reserves
- Pollution and environmental degradation
- High financial cost
- Security of supply
Electrical Energy
- Most preferred type of energy due to being clean and easily converted into other forms
- Electric energy generation converts other forms of energy into electrical energy.
- System efficiency is the ability to minimize energy loss during conversion.
World Energy Consumption
- Energy production by fuel is tracked from 1980-2035
Conservation of Energy
- Methods for using less energy include:
- Technical methods: Developing more efficient processes
- Adaptation of lifestyle and habits: Reducing consumption by changing lifestyles.
- Developing "Renewable" resources
Sources for Energy
- Energy sources can be grouped as:
- Renewable
- Geothermal
- Solar
- Direct
- Indirect
- Wind
- Wave
- Hydro
- Biomass
- Nuclear
- Fission
- Fusion
- Fossil Fuels
- Coal
- Oil
- Gas
- Peat
- Renewable
### Power Definition
- Power is defined as the rate of producing or consuming energy.
- Electrical energy is convenient because it's easily converted into other forms.
- It can be controlled, transmitted long distances quickly, and is relatively efficient.
- It's environmentally friendly.
- Electrical power must be transmitted from place to place.
- This process is called Electric Power Transmission.
- Power Distribution lets consumers use the energy as needed.
Power Systems Main Components and Function
- Modern power systems have three distinct components:
- Generation
- Transmission
- Distribution
- The function of a power system is to safely and reliably meet energy demand of residential, commercial, and industrial consumers.
The Structure of a Power System
- All power systems, regardless of size, consist of these parts:
- Generation plants
- Transmission system
- Substations to convert between different voltage levels
- Distribution system reaching all customers
Base Load, Intermediate Load, and Peak Load
- Base Load: Load demanded 100% of the time
- Peak Load: Load demanded for brief intervals during the day
- Intermediate Load: Area between peak load and base load
Power Station Types
- Four basic types of generating stations
1.3 Describe the layout of gas-turbine, hydropower, nuclear, solar and wind power generation plants
-
Common Electrical Power Generation Plants:
- Thermal generating stations
- Hydropower generating stations
- Nuclear Power plants
- Wind Power Stations
