I. Main Functions of the Parallel Cabinet
The automatic paralleling system provides a fully electronic protection system for faults such as short circuits, overloads, overvoltages, and reverse power in the generator sets. This ensures the safe and reliable operation of the generators.
When multiple generating units are connected in parallel, they can automatically allocate the active power load proportion, with the deviation not exceeding 10%.
Automatic frequency tracking and synchronous paralleling.
II. Advantages and Disadvantages of the Parallel Cabinet
1. Main Advantages
· After multiple generator sets are paralleled, according to the load size on the network, the appropriate number of generator sets can be put into operation to ensure the generator sets are operating in the best condition. This can save fuel and oil consumption (the fuel consumption rate is low under the rated load of 75% for the generator set), thereby achieving the goal of saving diesel and reducing power generation costs, bringing significant economic benefits to the enterprise.
· After the generator sets are paralleled, the power supply quality improves, the voltage and frequency of the power supply for electrical equipment are stable, and they can withstand the impact of large loads on the generator, reducing generator failures.
· After the generator sets are paralleled, they form a unified power grid. With centralized control, the power dispatching of the entire plant is flexible and convenient.
· The safety advantage of automatic paralleling and automatic active power allocation without manual operation.
2. Disadvantages
· A high-tech parallel cabinet system usually has an extremely low failure rate. Once a fault occurs, it requires professional maintenance companies with certain technical talents to repair it.
· The initial investment is relatively large.
