[0002] A diesel generator is a small power generation device, which refers to a power machine that uses diesel as fuel and a diesel engine as the prime mover to drive the generator to generate electricity. The whole set is generally composed of a diesel engine, a generator, a control box, a fuel tank, a storage battery for starting and control, a protective device, an emergency cabinet and other components. Diesel generators are widely used and can be used for daily power generation and emergency power generation in various homes, offices, large, medium and small enterprises.
[0003] When a diesel generator is used as a backup power source, it is usually connected to the load through a wire. When the mains power or power supply equipment fails, the diesel generator can be started to supply power to the load. Current diesel generators are usually installed with a self-starting system when in use. The self-starting system can automatically detect abnormal conditions and start the diesel generator when the mains power is off or the voltage is unstable, thereby ensuring the continuity and stability of the power supply. In addition, the self-starting system can also reduce manual intervention and operation, and improve the efficiency and reliability of the generator. However, when the self-starting control system is used, the self-starting and stopping module or the power supply line may fail. In this case, the staff cannot understand the cause of the failure in time, which will affect the timeliness of the backup power supply. Therefore, a self-starting control system for diesel generator sets is needed to solve the above problems. Utility Model Content
