Speed Control of Jichai Diesel Generator Diesel Engine

Jun. 06, 2023

After parallel connection, the connection between the two Jichai diesel generator is mainly on the bus, which is the end point of the diesel generator of Jichai. Therefore, the analysis of the problem must start from the electrical aspect. Each diesel generator of JICHAI consists of diesel engine, regulator, generator, voltage regulator and other links, and both ends of two diesel generator of JICHAI are connected in parallel through bus. The rotor of each JICHAI diesel generator is connected to the crankshaft of the diesel engine through a coupling. Since the rotor of JICHAI diesel generator and the rotating part of the diesel engine are a whole, the discussion on the rotor of JICHAI diesel generator actually includes the rotating part of the diesel engine, and vice versa.

For JICHAI diesel generator running on a single engine, the voltage regulator of JICHAI diesel generator can always automatically maintain the required accuracy by changing the excitation current of JICHAI diesel generator, without being affected by the load size and its components, and adjust the speed of JICHAI diesel generator. By adjusting the fuel supply of JICHAI diesel generator, the speed of JICHAI diesel generator is automatically kept within the required accuracy range.


From the perspective of electricity, it ensures the stability of the frequency and voltage of electrical equipment, balances the energy consumed by the load and the fuel energy supplied to Jichai diesel generator. If the external load of each JICHAI diesel generator does not exceed the allowable value of generator and diesel engine, the operation of JICHAI diesel generator will not be abnormal. Assuming that after the entire step, two units are connected in parallel and the switch k is closed.


Obviously, the function of the voltage regulator and speed regulator to keep the voltage and speed unchanged has not changed, but different from the previous function, the load originally borne by each Jichai diesel generator is now borne by two Jichai diesel generator, so in addition to the total energy balance. The functions of voltage regulator and speed regulator have not changed, so as to find out the load distribution law between parallel connected diesel diesel generator. Most problems in parallel operation are related to how to distribute the common load of parallel diesel generator.
