Abstract:

Shore power system is important for the environmental protection of power plants, especially the coal-launched power plants. Based on ensuring the safety and environmental protection and reliability, a suitable actual operation of the system structure for power plant dock was proposed. Compared with the traditional shore power, the concept of conversion and integration was put forward, compatible with both 400V/50Hz and 440V/60Hz ships docking at port. The main problems of cable system and grid-collected was analyzed. Finally, the cost and profit were analyzed, and it was pointed out that such a structure will greatly reduce the cost of the system. By taking advantage of the power plant's advantages in price, the low-voltage shore power system can be widely used in coal-launched power plant.

Key words: shore power, low voltage, grid connected, coal-launched power plant
