4 FAQs about Substation generator protection

What is generator protection system design?

The generator protection system design takes into account the types of faults and abnormal operating conditions that could be present at the generating plant and provide means for detecting and acting upon these conditions. The extent of the protection system design is dependent on the size and relative value of the generating unit.

How does a substation protection system work?

In a conventional substation protection and control scheme, protection is distributed or “de-centralized” among multiple Numerical Protection Relays. These devices typically operate independently, with minimal communication and coordination between them.

What equipment is used in a substation?

Within a substation, various equipment—such as switchgear, transformers, power system protection, communication devices, voltage regulators, and energy meters—work together to ensure the safe and efficient delivery of power. Substations vary in size and function.

What is an electrical substation?

An electrical substation is a critical component that transmits electric power from production to consumption. Within a substation, various equipment—such as switchgear, transformers, power system protection, communication devices, voltage regulators, and energy meters—work together to ensure the safe and efficient delivery of power.
