Question

difference between central and captive power station

Answer 1

Answer:

There is a significant difference between a Captive Power Plant (CPP) and a Cogeneration plant. ... In a Cogeneration setup, only the excess heat in the steam generated is used and remaining heat is used for the process requirement. Therefore, steam is not specifically generated for power production.

Answer 2

A captive power plant is a plant constructed to provide an electricity user with a decentralized power source. Usually these are manufacturing facilities or large offices. The plants will work in parallel to the ability to export surplus power to the local grid. The idea of building a large energy plant that supplies a great number of people instead of a distributed generation is just central power station, where all have (say) their own solar power

Explanation:

• Captive Power Plants: An electricity generation system, which is used by an industrial or commercial energy consumer for its own energy consumption, is a captive power plant, which is also known as auto-producers or built-in production. Captive power plants can operate outside the grid or link to the grid to exchange surplus energy.
• In general, power-intensive industries use captive power plants, in order to maintain stability and supply efficiency, such as aluminum casting, stainless steel, chemical, etc. Radical declines in the costs of solar systems have allowed less energy intensive industries to experience economic grid defects by combining solar photovoltaics with generators or cogeneration units with battery systems.

• Centralised Power station: Centralized generation "refers to large-scale power generation in centralized plants. These systems are generally located outside end-users and connected to a high-voltage transmission network.
• Central power station is referred to as large-scale power generation in centrally located plants. Generally located outside end-users, these systems are connected to a high voltage transmission network.
