What is a Generator Substation & how does it work?
Generating substations step up the voltage from the generator’s lower voltage to a higher voltage which is more economical for transmitting electric power over longer distances with less power losses caused by the impedance of transmission lines.
What does a substation do?
Substation transforms voltage from high to low or from low to high as necessary. Substation also dispatches electric power from generating stations to the consumption center. Electric power may flow through several substations between the generating plant and the consumer, and the voltage may be changed in several steps. Contents: 1.
What is a substation power transformer?
The substations contain power transformers that reduce the voltage from sub-transmission levels to distribution levels, usually in the range of 4.16Y/2.4 kV to 34.5Y/19.92 kV. The transformers are normally equipped to regulate the substation bus voltage.
What makes a good substation?
Ideal electrical substations have the following key features: separate breakers for each circuit and the ability to replace bus-bars or breakers during maintenance or faults. System security can be determined by allowing 100% dependence on substation integrity or allowing a percentage of downtime due to periodic faults or maintenance.
What are the different types of substations?
Substations can be generally divided into three major types (according to voltage levels): Transmission substations integrate transmission lines into a network with multiple parallel interconnections, so that power can flow freely over long distances from any generator to any consumer. This transmission grid is often called the bulk power system.
How much power should a substation have?
The capacity of any single substation at various voltage levels should not generally exceed. The size and number of interconnecting Transformers (ICTs) must be planned in such a way that the failure of any single unit does not overload the remaining ICTs or underlying system.
