Generator Protection Functions

The generator was invented by Faraday on September 23, 1831. It is a machine that converts mechanical energy into electrical energy. Electrical energy is one of the most important energy sources in modern society. Generators have the advantages of simple operation, high safety, intelligence, and good economic efficiency, and have been widely used in agricultural production, national defense, science and technology, and daily life. Then where does the generator show simple and intelligent operation? Let's take a look at the protection functions of the following major units to better understand.

Basic Four Protection Functions of Generator

1.High water temperature protection: When the water tank temperature of the mobile generator set reaches above 98 degrees, the generator's control module will detect the high water temperature warning and then shut down for protection.

2.Low oil pressure protection: When the oil in the generator is insufficient or reaches the warning level, the generator set will also issue a low oil pressure alarm and shut down.

3.Overcurrent protection: When the user's load exceeds the rated current of the gasoline generator set, the generator set will also shut down and alarm.

4.Overload protection: When the user's load exceeds the rated power of the generator, the generator will also alarm and shut down.

Main Protection and Backup Protection of 650kW Diesel Generator Set

1.Generator main protection: generator-transformer set differential protection (big differential), generator differential protection (small differential), generator transverse differential protection.

A. Longitudinal differential protection.

B. Turn-to-turn short circuit protection mainly includes: stator winding single-phase grounding protection; rotor winding grounding protection; generator loss of excitation protection.

2.Generator backup protection: failure startup, that is, the protection for tripping the upper-level switch.

When the generator protection acts, if the generator protection refuses to act or the switch refuses to act, it cannot trip and shut down. Then start the protection of the adjacent components of the generator and trip the switch of the adjacent components.

Backup protection also includes: stator winding overcurrent protection caused by external short circuit; stator winding overload protection; rotor winding; rotor surface overload protection; stator winding overvoltage protection; reverse power protection; loss of synchronization protection; overexcitation protection; low frequency protection, etc.
