Power system automatic devices refer to equipment and systems used to monitor, control and protect power systems. These devices can automatically perform a series of functions to ensure the safe, stable and efficient operation of the power system. They mainly include the following categories:
1. Monitoring devices: real-time monitoring of the operating status of the power system, collecting data such as current, voltage, frequency, etc.
2. Control devices: automatically adjust the operating status of power generation, transmission and distribution equipment according to monitoring data, and optimize power flow.
3. Protection devices: when a system failure occurs (such as short circuit, overload, etc.), quickly cut off the faulty part to prevent the fault from expanding and ensure system safety.
4. Dispatching system: used to dispatch power production and consumption to ensure the balance between power supply and demand.
5. Automation system: integrates advanced information technology and communication technology to realize the automated management of power systems.
These devices improve the reliability, stability and economy of power systems and are an indispensable part of modern power systems.
