HVDC Transmission DefinitionHVDC transmission is the method of transmitting electricity in DC form over long distances using either submarine cables or overhead lines.Conversion and ComponentsThe hvdc transmission system uses rectifiers and inverters for converting AC to DC and vice versa, with components like smoothing reactors and harmonic filters to ensure stability and reduce interference.HVDC Transmission SystemWe know that AC power is generated in the generating station. This should first

What is a Load Curve?Load Curve A load curve is defined as a graph that shows how energy demand varies over time from a power source.If the curve covers 24 hours, it is called a daily load curve. For a week, month, or year, it is called the weekly, monthly, or yearly load curve.The load duration curve reflects the activity of a population quite accurately with respect to electrical power consumption over a given period of time. To understand the concept better its important that we take the real

What is Electrical Grid System ?Electrical Grid System DefinitionAn electrical grid system is defined as a network connecting multiple power-generating stations at a specific transmission voltage level. Increased ReliabilityAn interconnected grid boosts the reliability of the power system by sharing loads in case of generating station failures.Load SharingThe grid system can exchange peak loads, reducing the need for partial load shedding or increasing the generating station’s capacity.Use of In

Auto Reclosing DefinitionAn auto reclosing scheme is defined as a system that automatically attempts to close circuit breakers after a fault, restoring power without human intervention. Fault Types Transient Fault Semi Permanent Fault Permanent Fault Auto Recloser Working PrincipleThe extra high voltage transmission lines transmit huge amount of electric power. Hence, it is always desirable that the continuation of power flow through the lines should not be interrupted for a long time. There may

What are Thermoelectric Power Generators?Thermoelectric Generator DefinitionA thermoelectric generator (TEG) is a device that converts heat energy into electrical energy using the Seebeck effect. The Seebeck effect is a phenomenon that occurs when a temperature difference exists between two different conductors or a circuit of conductors, creating an electric potential difference. TEGs are solid-state devices that have no moving parts and can operate silently and reliably for long periods of tim

Electrical Supply System DefinitionAn electrical supply system is defined as the network delivering electricity from generating stations to consumers, including transmission and distribution.In the past, the demand for electrical energy was low, and a single small generating unit could meet the local needs. Now, with modern lifestyles, the demand has skyrocketed. To meet this growing demand, we need many large power plants.However, building power plants near load centers, where many consumers ar

Definition of Economics of Power GenerationIn modern engineering projects, cost is very important. Engineers must achieve the desired results at the lowest cost. In power generation, we often choose between high-cost, high-efficiency equipment and low-cost, lower-efficiency equipment. High-cost equipment has higher interest and depreciation charges but lower energy bills.Electrical engineers must balance costs to minimize total plant expenditure. Studying the economics of power generation is cru

What is Nuclear Power PlantA nuclear power plant generates electricity by using nuclear reactions, mainly through nuclear fission.Nuclear FissionNuclear fission splits heavy atoms like uranium into smaller parts, releasing a large amount of energy.Main ComponentsIn the fission process, the nuclei of heavy radioactive atoms are broken into two nearly equal parts. During this breaking of nuclei, a huge quantity of energy is released. This release of energy is due to a mass defect. That means the t

What is a Hydro Power Plant?Hydroelectric Power Plant DefinitionA hydroelectric power plant is defined as a facility that generates electricity by using the kinetic energy of falling water to rotate a turbine.In hydroelectric power station the kinetic energy developed due to gravity in a falling water from higher to lower head is utilised to rotate a turbine to produce electricity. The potential energy stored in the water at upper water level will release as kinetic energy when it falls to the l

What are Power Transmission Systems?Power Transmission Systems DefinitionPower transmission systems transmit electrical power from generating stations to load centers where it is consumed.Electric power transmission systems are the means of transmitting power from a generating source to various load centers (i.e. where the power is being used). Generating stations generate electrical power. These generating stations are not necessarily situated where the majority of the power is being consumed (
