Know the Structural Components of the Power System

-

How electricity reaches from power station to your residence? Have you ever pondered over the fact? One answer to all your concern is the power system. It is the network that consists of power generation, distribution, and transmission of energy. Several devices, like synchronous generator, motor, transformer, circuit breaker, conductor, etc., are an integral part of this network. It is a complex structure subdivided into the following sub-systems. For more details on it, read the following blog or view Power System Analysis and Design 6th Edition Solutions Manual.

Structure of the Power System

Generating Substation

Generating station coverts natural fuels like coal, water (for hydroelectricity), nuclear and others into the electrical energy. The power generated under this station ranges between 11kV to 25kV, used for long-distance transmission. Its power plant is classified into three major types, i.e. thermal, hydropower, and nuclear power plant. The main components of generating substations are the generator and the transformer.

Transmission Substation

Transmission substation carries the generated power through overhead lines from generation center to distribution substations. It supplies the bulk of energy power substations or huge consumers. The transmission lines transport the electrical energy from generating stations to several receiving ends. Also, it interconnects two or more generating stations, including the neighboring substations.



Sub transmission Substation

A sub-transmission system is a component of a transmission system that connects high voltage substations to distribution substations via step-down transformers. The sub-transmission system directly serves some large industries. The capacitor and reactor are located in the substation to handle the transmission line voltage.

Distribution substation

The distribution system is the electrical power system that connects all the consumers in an area with substantial power sources. Bulk power stations are connected to substations generated by transmission lines. They usually eat at certain substations located at the vantage points near the load stations. Substations distribute electricity to domestic, commercial, and relatively small consumers. Consumers require large amounts of power that are usually supplied in sub-transmission or transmission systems.

Final words

The network of the power system is complex, and you need a proper understanding of the subject. For beginners, this post can be an easy guide for basic knowledge of the power system. Electricity is not so easy to understand, that’s why there is a professional course in high education ‘Electrical Engineering’. If you want to gain expertise in the power system module, enroll in this course.

Applications of Multirate and Wavelet Digital Signal Processing

 Radio transmission, CD, DVDs, and other gadgets work on the principles of digital signal processing. It is not limited to only one type, but there are many signal processing types like audio signal processing, digital image processing, and much more. Two important ones which are used primarily by us are multirate and wavelet. In this blog, we delve into some facts and applications. Wavelets are functions that you can use for signal decomposition. Like the Fourier transform decomposes a signal into a complex sinusoid family, the wavelet transformation converts a signal into a wavelet family. ·          The wavelet transition simplifies multiplexing analysis because the waveform transition is applied back to the signal to achieve any level of accuracy. In short, the wavelet transition allows multiple observations of the signal, from a rigorous observation of the signal to a detailed, accurate view of the signal. ·          Noise removal is the most commonly cited application of wa
