What are electrical substations?
Electrical substations are critical components of the electrical grid, ensuring that electricity generated at power plants is efficiently transmitted, distributed, and delivered to consumers. Substations play a vital role in managing the flow of electricity, allowing for reliable and safe power distribution across long distances.
How does a substation work?
Substations contain the specialist equipment that allows the voltage of electricity to be transformed (or ‘switched’). The voltage is stepped up or down through pieces of equipment called transformers, which sit within a substation’s site. Transformers are electrical devices that transfer electrical energy by means of a changing magnetic field.
Why do substations need advanced control systems and energy storage technologies?
Substations equipped with advanced control systems and energy storage technologies can store excess renewable energy during periods of high generation and release it when generation is low. This capability is crucial in ensuring that renewable energy can be reliably integrated into the grid.
Do substations produce energy?
Substations don’t produce energy but instead regulate it, allowing the efficient transportation of large volumes of electricity over the transmission network, and the conversion required for this electricity to be used in homes and businesses. Transforming the grid
What are the components of a substation?
The primary components of a substation include: Transformers: These devices change the voltage levels of electricity to make it suitable for either long-distance transmission (high voltage) or local distribution (low voltage). They consist of a core and windings that convert electrical energy through electromagnetic induction.
Why do we need electricity substations?
Electricity substations are an essential element for the operation of the electricity grid as well as for ensuring a stable and secure supply of electricity.
