What are the three common startup methods for diesel generator sets in parallel automatic mode? In the automatic mode of diesel generator set parallel operation, there are three common starting methods: starting according to demand, starting all, and balancing the engine running time. Below, we will elaborate on them. Firstly, it is necessary to start the machine according to the demand. In the automatic mode of diesel generator set parallel operation, when the switch input port remotely starts and the load is effective, the module with the highest priority will start the machine first. When the load is greater than the maximum percentage set by the module for starting, the module with the second priority will start the machine, synchronize the parallel operation, and evenly distribute the load.
When the load is less than the minimum percentage of shutdown set by the module, the sub priority module will shut down for heat dissipation after the shutdown delay is completed. When the loaded diesel generator set alarms and shuts down, the second priority module starts up. When all modules are turned on, the transformer manufacturer reminds that in the automatic mode of diesel generator set parallel operation, when the remote start of the switch input port with load is effective, all modules will be turned on, and the modules with load conditions will be closed first. After other modules meet the load conditions, they will be synchronized for parallel operation. Then the module detects the load, and when the load is less than the minimum percentage of shutdown set by the module, the module with lower priority will shut down for heat dissipation after the shutdown delay is completed. When the load exceeds the maximum percentage set by the module for startup, all remaining generators that have not been started will automatically start up.
When the loaded generator unit alarms and shuts down, all remaining units that have not started will automatically start up. When starting the diesel generator set with a balanced engine running time, in the automatic mode of parallel operation of the diesel generator set, the diesel generator set with a small engine running time is first started when the remote start of the switch input port is effective with load. When the running time of the loaded diesel generator set is greater than the equilibrium engine running time set by other diesel generator sets, the other sets are scheduled to start up, and the other diesel generator sets are synchronized and connected. Self opening, unloading and shutdown, all diesel generator sets will automatically start and stop according to the size of the balanced engine operating time in turns.
