System frequency refers to the rate at which alternating current (AC) changes direction per second, measured in Hertz (Hz), and is crucial for the stability and synchronization of power systems. It ensures that all connected devices operate in harmony, preventing damage and ensuring efficient energy distribution.

System frequency

Alternating current (AC) is an electric current that periodically reverses direction, in contrast to direct current (DC) which flows only in one direction. AC is the form of electrical power that is delivered to homes and businesses, and it is the form of electrical energy that consumers typically use when they plug appliances into a wall socket.

Hertz (Hz) is the unit of frequency in the International System of Units (SI) that measures the number of cycles per second of a periodic phenomenon. It is widely used in physics, engineering, and technology to describe the frequency of waves and oscillations, such as sound waves, electromagnetic waves, and alternating current in electrical circuits.

Hertz

The stability of power systems refers to the ability of an electrical power system to return to a state of equilibrium after being subjected to a disturbance, ensuring continuous and reliable operation. It is crucial for preventing blackouts and maintaining the quality of power supply, involving complex interactions between system components and control mechanisms.
