Diesel Generator Set Parallel Cabinet Project in the Philippines

In modern industrial and commercial facilities, the stability and reliability of the power supply is critical. For environments with high power demand and extreme sensitivity to power interruptions (e.g., data centers, hospitals, large industrial facilities, etc.), it is often difficult for a single genset to meet the load demand or respond to emergencies. Therefore, the design and implementation of diesel generator parallel cabinet system to realize the parallel operation of multiple generator sets has become an effective solution.

Diesel generator sets and cabinets, also known as generator automatic control cabinet, is when two or more diesel generator sets jointly to the load power supply or power supply to the grid, for the realization of the joint power supply requirements of multiple units of equipment.

Through a highly automated control system, the parallel cabinet can ensure the stability and reliability of power supply when the demand changes or some units fail. The basic functions of the parallel cabinet include automatic monitoring, manual/self-start selection, emergency stop control, and automatic parallel closing. Specifically, when the utility power fails, the parallel cabinet can automatically start the standby diesel generator set and turn on another set automatically when the load reaches the set value. At the same time, the system will automatically distribute the active load evenly, and has automatic frequency tracking, inverse power and over-power detection and protection functions.

The advantages of parallel cabinets are significant, mainly in improving the reliability and continuity of the power supply system. As multiple units are connected into a power grid in parallel, they can withstand the impact of large load changes, thus ensuring the stability of power supply voltage and frequency. At the same time, it is also more convenient in maintenance and repair, because the parallel use of multiple units can realize centralized scheduling and load distribution, making maintenance and repair more timely and convenient.

Moreover, the use of parallel cabinets also has a high degree of economy. According to the size of the online load, the appropriate number of small-power units can be put into the system, reducing the waste of fuel and oil when the high-power units are running at small loads. In addition, the parallel cabinet also provides greater flexibility for future expansion, only need to install the required power generation and paralleling equipment, and then increase the generator set when the need to expand the grid capacity.
