Three 175KW gensets are in the network, the load percentage is less than 30%, and the No.3 genset with low splitting priority is in the network
Recently, the power station of "Guangxiao 05" catamaran fire-fighting boat built by JiangLong Ship Building on the coast of the South China Sea has successfully passed the CCS acceptance. The successful acceptance of the automatic power station marks that the ship is one step closer to the mooring navigation test. The on-site commissioning personnel of Zhongzhi technology company will witness this exciting momentstogether with the project management personnel of JiangLong Ship Building, the manufacturer of main switchboard and the manufacturer of main genset.
Guangxiao 05 in Berthing State
The power management system is built by three multi master power management controllers HMC6 and its auxiliary expansion modules on the main distribution board. The system is set in manual and automatic modes, and the startup sequence can be adjusted arbitrarily. In automatic mode, three main gensets can be automatically synchronized and combined according to the priority, and can be automatically adjusted in frequency and load during parallel operation to quickly complete the balanced distribution of active power. When the genset is running with heavy load, the online genset will be increased, and when the load is light, the online genset will be reduced. When the online genset fails, the standby genset will start automatically and automatically start, and the failed genset will automatically exit. When a single genset fails and loses power, the standby main genset can start on its own and close within 30 seconds for power supply. The system can also automatically close and disconnect the disconnector between the busbar A and busbar B. The high-power side thruster has the function of heavy load inquiry, and the system has the function of automatically unloading the non-important load when the parallel operation of the main genset is overloaded.

With the help of HMC6 power management controller's built-in power management strategy and rich adjustable parameters, users can quickly realize the balanced distribution of active power and load distribution precision under the harsh conditions of any combination of three units, such as extremely fast synchronous parallel operation, different load percentage, sudden load increase and sudden discharge, etc. by modifying a small number of core parameters in a short time within 3%.
Introduction of the Core Functions of Multi Master Power Management Controller HMC6
Power Management Solution of HMC6 with HMC9000 Diesel Engine Control Box
The system builds a real multi master station system through MSC communication network (CAN bus), and its power management function is realized by the calculation of all generator control units. In the system, a control unit is selected as the "instruction unit", which is responsible for the calculation of the starting priority and other related power management functions of the genset. It can realize automatic synchronization and load distribution of up to 16 gensets. If one control unit fails, the power management calculation will be automatically transferred to the next available control unit.
