An ordinary diesel generator set mainly consists of a diesel engine, a generator, and a control system. There are two connection methods for the diesel engine and the generator: one is a flexible connection, where the two parts are connected together using a coupling; the other is a rigid connection, where the generator’s steel connecting plate and the diesel engine’s flywheel disk are connected using high-strength bolts. Currently, rigid connections are more commonly used in the market for diesel generator sets. After the diesel engine and the generator are connected, they are installed on a common base frame, and then various protective sensors are equipped, such as the water temperature sensor. Through these sensors, the operational status of the diesel engine is visually displayed to the operator. With these sensors, an upper limit can be set. When this limit is reached or exceeded, the control system will give an early warning. If the operator does not take measures at this time, the control system will automatically shut down the unit. The diesel generator set takes this approach to protect itself.
Sensors play the role of receiving and transmitting various information. The actual display of these data and the execution of protection functions are carried out by the control system of the diesel generator set. The control panel is generally installed on the generator and is called a backpack control panel. Some are placed independently in an operating room and are called a split control panel. The control panel is connected to the generator and the sensors through cables, displaying electrical parameters and diesel engine operating parameters respectively.
Among these three components, both the diesel engine and the generator are produced by professional manufacturers, while the diesel generator set manufacturer actually produces the control system. Therefore, when the diesel engine and the generator are configured with the same manufacturer and the same model, the performance indicators of a unit can only be evaluated by its control system’s quality and the quality of the components selected, and the performance of the control system is often overlooked by users. Therefore, I would like to emphasize this point here.
