Diesel generator set power supply

When powering the diesel generator set, the voltage and current of the diesel engine company and the oil pressure of the perkins generator  must also be detected. In normal operation, when the detected voltage and frequency exceed the set upper and lower limits (load), the load is cut off, and the perkins generator is in no-load operation; in no-load, if the detected voltage and frequency exceed the When the upper and lower limits are set (no load), the diesel generator is considered to be faulty and an error will be reported when it stops. No matter it is under no load or under load, as long as it is detected that the oil pressure of the diesel generator is low, the diesel generator is considered to be working abnormally and an error will be reported when it is stopped. The system also has an excitation regulating device, which can realize low-frequency protection of diesel generator sets. When the frequency of the system power supply is low, it can play a protective role. At the same time, through the vector synthesis of voltage and current and ND adjustment, it can keep diesel power generation. The output voltage of the unit can make the output voltage change less than 1% even when the load has a large change, so as to ensure the normal operation of the load (equipment).

Taking into account that the power grid sometimes has short-term power supply, in order to avoid frequent switching of equipment power supply, in this state, if the power grid returns to normal, it will be switched to the grid running state after a few seconds delay, and then a few minutes later. Stop the diesel generator operation. In this way, it can be ensured that only after the grid has indeed returned to normal, the power supply will be switched to the grid, and at the same time, the frequent starting of the diesel generator can be avoided.
