With the continuous improvement of the ship informatization and intelligence, the traditional ship power distribution monitoring system cannot meet the requirements of the power distribution control and management of modern ships as it has backward management, insufficient remote control and low intelligence level. An intelligent power distribution monitoring system is then designed aiming at the above problems. It presents the composition of the system, the system communication network and the software and hardware of the system. This system adopts the hierarchical distributed layout and delivery data through Ethernet or CAN bus. It has the functions of the real-time monitoring of the power distribution network of the whole ship, centralized data management, remote control of the load power supply and the intelligent power distribution control.

The frequent operation of the high-power pulse load equipment will affect the voltage and frequency of the power grid for the ships equipped with the high-power pulse load equipment. Based on the power station configuration of the power system of the full-scale ship, it analyzes the power supply programme according to the operation conditions of the high-power pulse load equipment, and proposes the corresponding load characteristic programme for the high-power pulse load. It also summarizes the relevant technical data of the generator sets, high-power pulse load equipment and electric propulsion equipment. The theoretical analysis and simulation of the key indicators, such as voltage, frequency and harmonic content of the power grid with the application of high-power pulse load, are carried out according to the actual operation conditions. Corresponding solutions are then proposed to ensure the normal operation of all the electrical equipment in the power grid.
