Electrical Supply Network
Electrical Supply or Electricity is generated at power plants and passes through a complex system, sometimes called a grid, electrical substations, transformers, and power lines that connect producers and consumers of electricity. Most local area networks are interconnected to provide reliability and business objectives, forming larger and more reliable systems that improve coordination and power planning. All power sources have an input power connection, which receives electric current from the source, and one or more output power connections that supply current to the load.
The energy source may come from an electrical network, such as an electrical outlet or Electrical circuit. Energy storage devices such as batteries or fuel cells, alternators or alternators, solar energy converters, or other power sources. The input and output typically wired connections, although some power supplies use wireless power to power their loads without wired connections. Some power supplies also have other inputs and outputs for functions such as external monitoring and control.
Therefore, we must create electrical grid systems to deliver the generated electrical energy from the power plant to end-users. Consumers enrich electricity generated by power plants through systems that we can divide into two main parts, called transmission and distribution.
We call the network through which consumers receive electricity from the source, as a power supply system. The power supply system consists of three main components: generating stations, power lines, and distribution systems. Power plants generate electricity at a relatively lower voltage level. Generating electricity at a lower voltage level is economical in many ways.
Classification of Electrical Supply Distribution
Alternating current electric power supply distribution systems can be classified by the following properties:
Frequency: 50 Hz and 60 Hz
Single phases And Three-phase
The numbers of wires electrical power supply distribution systems
2, wires system 1 Phase and 1 Neutral Supply system
3, wires system, Phase Supply system Supply system
4, wires system,3 Phase, and 1 Neutral Supply system
Star connected systems have a neutral and Delta connected systems typically do not have a neutral
Electrical Power Supplies
Power is the foundation of any electronic system, and the power source is what powers the system. Choosing the right power source can be a critical difference between a device operating at an optimal level and a device that can produce conflicting results. While a power source is an electrical device that supplies electricity to an electrical load.
Although The main function of the power source is to convert the electric current from the source to the correct voltage, current, and frequency to power the load. As a result, power supplies are sometimes referred to as power converters. Some power supplies are separate, individual pieces of equipment, while others are built into the load devices that they drive.
Examples of the latter include power supplies that can be found on desktop computers and consumer electronics devices. Other functions that power supplies can perform include limiting the current consumed by the load to safe levels. Turning off the current in the event of an electrical failure, conditioning the power supply to prevent electronic noise or power surges at the input of the load, factor correction, and energy storage so that it can continue to power the load in the event of a temporary interruption in the power source (UPS).
