Role and Function of Governor in Cummins Diesel Generator

The rated speed of our Cummins diesel generator is 1500 rpm. For the generator set to maintain a stable speed, a governor is required. The governor can automatically adjust the fuel supply according to the load changes of the diesel generator set. It can be said to be an essential factor for the stability of the Yuchai diesel generator.

Now, let's specifically talk about the two main uses of the governor:

1. When the speed of the Cummins diesel generator deviates from the set value, the governor can promptly make corresponding reaction actions. It also has the function of a restoring force to return the governor to its initial state. You should know that the spring in the centrifugal governor of our diesel engine parts is the part that generates the restoring force. Such a governor is also called a statically stable governor. However, a statically stable governor may also experience dynamic instability during the adjustment process. When the adjustment action is excessive and reverse adjustment occurs, in fact, the adjustment action will form an oscillation process. A governor that can quickly reduce the oscillation is called a dynamically stable governor. Otherwise, it is a dynamically unstable governor, and the latter cannot fully guarantee the normal operation of the diesel generator set.

2. Adding damping to the diesel generator set's adjustment system is also a commonly used method to improve dynamic stability. The damping in the adjustment system, such as the friction in the kinematic pair, makes the governor have a certain degree of insensitivity. In other words, when the speed of the controlled shaft slightly deviates from the set value, the governor will not produce a corresponding action. The insensitivity of a mechanical governor is generally about 1% of its set value. On the contrary, a governor with excessively high sensitivity will also produce unnecessary adjustment actions due to the periodic speed fluctuations during the normal operation of the diesel generator.
