Experiments Related to Diesel Generator Set Governor

The engine electronic governor is one of the key components of the diesel generator set. When the actual diesel generator set and its load performance change and do not match the design parameters of the governor, the diesel generator set cannot work normally. speed control parameters.

The engine electronic governor is one of the key components of the diesel generator set. When the actual diesel generator set and its load performance change and do not match the design parameters of the governor, the diesel generator set cannot work normally. speed control parameters. In addition, the electronic governor needs to be tested for performance before leaving the factory and after maintenance, so as to set appropriate control parameters to meet its adjustment performance. It is neither safe nor economical to perform parameter setting, performance test and performance recovery of the electronic governor directly on the engine.

 

The semi-physical simulation is an indispensable link before the actual distribution test of the governor. The engineering idea is to establish a dynamic simulation model of the full working range of the diesel generator set, and connect it with the electronic governor through the input and output interface circuit to form a closed-loop control system. , so as to complete the relevant test of the performance test of the electronic governor.

Building a simulation model of a diesel generator set is Simulink's strength. Since the semi-physical simulation system needs to be connected to specific hardware devices, the simulation program needs to customize the human-machine interface to realize functions such as parameter setting. The realization of this part of the function is difficult for Simulink to complete, and this is precisely the strength of Visual C++ (VC). The VC visual C++ programming environment has powerful hardware control functions and flexible and rich man-machine interface design functions. But it is very difficult to directly use VC to establish the simulation model of diesel generator set.

Aiming at this problem, this paper provides a method for smooth transition from Simulink simulation model to VisualC++ integrated development environment. The specific implementation is to establish a simulation model of diesel generator set in Simulink, and then convert the Simulink simulation model into a portable embedded C++ code through the Matlab real-time workshop (RTW), and then integrate it with the VisualC++ project file to form a completely independent operation. Real-time semi-physical simulation system.
