Manual parallel operation: Manual parallel operation refers to the manual operation of switches, buttons, and other equipment on the parallel cabinet to achieve parallel operation of the generator set. Manual parallel operation requires operators to have certain professional knowledge and skills, and the operation process is relatively complex and prone to misoperation. Therefore, manual parallel operation is generally only suitable for small generator sets or temporary emergency situations.
Automatic parallel operation: Automatic parallel operation refers to the automatic parallel operation of the generator set through the automatic control system inside the parallel cabinet. The automatic parallel system can automatically start and stop the generator set according to changes in load, and achieve automatic power distribution and adjustment. It is easy to operate, convenient, and highly reliable. At present, automatic parallel operation has become the main method for power generation unit parallel operation.
Precautions for parallel operation of generator sets
Before parallel operation, strict inspection and testing should be carried out, including parameter inspection of the generator set, phase sequence inspection, speed regulation characteristics, and voltage regulation characteristics testing. Only when ensuring that each generator unit meets the conditions for parallel operation, can parallel operation be carried out.
During the process of parallel operation, close attention should be paid to the operating status of each generator unit, including changes in parameters such as output voltage, frequency, current, and power. If any abnormal situation is found, the parallel operation should be stopped immediately and checked and handled.
After merging, regular maintenance and upkeep should be carried out on the merging cabinet and generator set, including checking whether the electrical equipment and connection lines inside the merging cabinet are normal, cleaning the radiator, air filter and other components of the generator set, and replacing vulnerable parts such as oil and filters. Only by doing a good job in maintenance and upkeep can we ensure the long-term stable operation of the parallel system.
In summary, the parallel operation technology of generator sets is an important means to improve the reliability and flexibility of power supply. Through a reasonable parallel operation plan, synchronous adjustment, professional operation and maintenance, the stable operation and efficient output of the parallel system can be ensured, providing a solid barrier for modern power systems.
