Why must the generator room be clean and free of floating sand on the ground

Why must the generator room be clean and free of floating sand on the ground

If a diesel engine sucks in dirty air, its power will decrease; If the generator absorbs impurities such as sand particles, the insulation between the stator and rotor gaps will be damaged, even leading to burnout.

What are the conditions for parallel operation of two generator sets? What device is used to complete the parallel operation

What are the conditions for parallel operation of two generator sets? What device is used to complete the parallel operation

The condition for parallel operation is that the instantaneous voltage, frequency, and phase of the two machines are the same. Commonly known as "three simultaneities". Use a dedicated parallel device to complete the parallel operation. It is generally recommended to use fully automatic cabinet merging. Try not to manually merge the machines. Because the success or failure of manual parallel operation depends on human experience. Based on more than 20 years of experience in electric power work, the author boldly states that the reliable success rate of manual parallel operation of diesel generators is equal to 0. The concept that a large power supply system can be manually connected to a small power supply system cannot be applied because the protection levels of the two systems are completely different.
